1. Intro to AutoCAD Masterclass Training Series: hi and welcome to our auto cad masterclass training course on this course I'm joined by, my colleague wrote, Who is an exceptional cab designer and instructor. World will take you from knowing nothing about AutoCAD to a level where you can tackle pretty much any cat project. There is no doubt that auto Cat is the best and the most popular technical drawings off their out there today, And on this course you'll learn how to navigate the ultra cat interface, draw basic and complex shapes and plans some off the most useful commands. Work with layers at dimensions, print and publish your project. This course will also prepare you for the official certification exam for also can, which will give you the competitive edge when you apply for AutoCAD jobs. Even if you are an existing AutoCAD user, this course will give you the extra skills to speed up and optimize your workflow alongside the training videos. You will also have access to the training files used during the course so you can follow along at your own pace. So if you're ready to learn AutoCAD, let's get started 2. Welcome: Hi. Welcome to our AutoCAD training videos. I'm really pleased you've decided to join us on the journey into or card, which is the leading CAD software anywhere in the world. Order. Cat has millions of users across the globe. Wherever you go, cad jobs ask for AutoCAD experience. Architects, engineers and designers all recognized the importance of water Cat on the ability to exchange data easily and freely. That makes economic sense on business. Loves it. If you have all declared on your CV, you're halfway there. 3. Why AutoCAD: you may ask, why auto cad? That is why I oughta cad in particular. Well, that's an easy question to answer. AutoCAD has been going for close on 40 years. The software has millions of users worldwide. The program is refined regularly and updated every year. It's easy to use and it's reliable, and I'm gonna show you how to get really good at using the world's favorite CAD package. 4. Download Files: So we've produced a series of videos to help you journal to cut on. We've also made drawings for you to follow at your own speed. So if you have a copy of or cat, have it open and you can work along with me, download the drawings and have them ready. Practice is a great thing, and we'll help you build up your kinetic muscle memory and improve your speed of operation and get you really good at order. Cad. So when you're ready, let's get going. 5. Version 2019: So I'm using AutoCAD 2019. Yeah, and, Ah, that's certainly the current version available right now. But you could also have a work alongside me using version 2015 or 16 or later on. There would be little appreciable difference. There might be some minor changes to the interface on graphics on the buttons, but that's about it. So let's press on. 6. Tips About the Interface and Keyboard Shortcuts: So I want to tell you how we're going to use and learn order, Kid. During these training videos, we're going to mainly rely on the command line than that's down here. This is the command line here. Now, some of you may have an interface where the command lines being moved and you can move the command line around and you can accidentally close it down. So don't don't do that about mainly, the command line appears at the bottom here. We're gonna be relying on typing in air commands at the keyboard on Whenever you type in a command, you have to finish with the enter key. So if the command was copy, you do copy, Enter. Now, of course, What we could do is we could use all of these buttons up top here. Okay, But really, all days do is to issue the command that weaken issue at the keyboard on The reason for that is the AutoCAD was designed before Windows was even available. So Windows came in around about 1990. Auto cad came in about 1980. So you can imagine Alter cat was around and designed before windows, so these buttons at the top here are just a convenient way of issuing the commands. Now, yes, there are a little bit more to the buttons than just the commands that we can issue. But in the main, the fastest way of using AutoCAD is through the keyboard. Now on the top Here, we've got a whole bunch of menus on. If I click through here, you can see that the ribbon changes as I go through. Of course, what that would mean is that you have to remember every single instance of every single but and every single menu. Now, of course, you could do that and you could go through and you could have a look at all of these extra pull down items. But really, once you know what the commands are, you can go for the commands on the keyboards very easily and very quickly, So that's the quick way of using AutoCAD. So I'm going to teach you what the commands are so you can hear the commands. The commands are in English so that they make sense so you can understand the logic. Most commands have a short cut so that you don't have to worry about typing errors. Okay, so, for instance, move is m okay. And it raise is E. So they're really easy. They're not really difficult shortcuts. And what we need to do is we need to take those short cuts on board, because typing in em for move avoids typing errors. Okay? And it also reduces time. And if you know what the command is and you get straight to it, it speeds up your drafting inside order card. Okay. So you could be quick and fast and accurate if you learn the keyboard. 7. BC Getting Around the Interface: so looking at the interface inside AutoCAD right the way across the top. Here, this is the button bar. As we said before and over here on the top left hand corner. We've got two tabs on these tabs. Allow us to go to the start menu and this is the start drawing menu. These are previously Lee used drawings and this is your online presence on any of the other drawings that you've got open Appear in a tab across the top here. And over here on the right is the properties dialog box. Now, you probably started order card without this. Actually, um, where this properties dialog box wasn't open. Probably like this on DA The Properties dialog box is a fantastic dialog box to have open. And it's just easy to get hold of the properties dialog box You've got Ah, right click menu here. So you can select Properties dialog box here, Onda, we're gonna be talking about that later. How you access it, how you use it and why it's important. And down here on the right hand side, there's a whole bunch of buttons here. You can see them. Some of them are turned on some of the grey graze turned off. Okay, Now I'm going to suggest that you don't fiddle with these buttons at all because these buttons alter the way in which order cared operates on Until you know what these buttons do , you could be turning on or off something absolutely fundamental. So I'm going to suggest that you don't change these buttons, Atal, until we've discussed them on duh, you know exactly what's going on. So there's a whole bunch of things that you could do Great. There's all sorts of little menus that you can access. Uh, but when you know what those menus are on, why you're going for them? Brilliant. But until that, avoid those buttons down in the bottom, right hand corner completely. And over here on the bottom left hand corner, we've got some buttons and tabs that allow you into paper space. So here we've got the A four layout and you've got a a one lout. So I'm just gonna open up each of those just by clicking on the tabs. Those tabs are a little bit like the tabs that you might find in Excel, for instance, if you know, excel on that just allows you to separate pages. Okay. And then this is paper space on. Then we can go back to model space. Okay, Now, paper space is used for printing and saving. Okay, So you could save out to pdf, for instance, or you could print out to your printer, and we're gonna cover all of that in a later video. But, um, if we come back to model space, okay, Right at the bottom. Here. We have something we mentioned earlier. The command line. Okay. Now, this is probably the most important area off water card. And this is how you talk to order card and how autocad talks to you. You type in at the keyboard and press enter, and that's your way of talking toe order cared, and it appears in the command line. And then AutoCAD responds. So what you want to do? Great eso, for instance, if you typed in a raise, great. Enter that. We are. There's theories command in the command line. And then auto card says Okay. Would you want to do please select some objects game so we'll do that was select some objects. And then when you finished selecting you just press enter okay on the objects of being erased. So that's a pretty straightforward way of operating. Okay, now, you can also get all of that stuff back, right? Don't worry about the fact that you've just done something. If you've made a mistake you can undo on, there's a lot of different ways that you can undo. For instance, you enter. So that's the you on the keyboard. The letter u ah percent and that's under You've got control said that which is a standard Windows command. That's undue. And up here in the top left hand corner, can you see this button that's pointing over to the left? That's also undo Brilliant. So you've got a lot of control over what's going on, okay? And auto cad has got around about 20 undoes that it could remember. I think you can alter in preferences, I think, alter how many undoes it could go back through eso. There we go. That's the interface on that. That's how we're going to be using water kids. So quick. Summary. Okay, Although these buttons air useful, we're not going to be using very many off them the properties dialog box is absolutely essential. Once you get used to it, it's brilliant. So we're gonna have that open on the right hand side. Don't touch these buttons down here until we've discussed how to use them. And right in the middle of the command line, we're gonna be typing our commands in at the keyboard. We're gonna be using short cuts on DA When we find out what those shortcuts, I'll tell you as we go, then learning the short cuts will make you more efficient. Okay? And avoid things like spelling mistakes. Okay, great. So that's the way we're going to be using AutoCAD in these tutorials. 8. Zooming and Panning: Hi. This is video number five, and it's all about zooming and panning. So if you've downloaded the drawings we've made to accompany this video, then open up drawing number five zoom and pan, and you can work alongside me. So this is all about zooming and panning around the drawing so that you can get the most out of your drawing experience. So if you're ready, let's have a look at your mouse. First at the center wheel in the middle of your mouse button is zoom, so if you want to scroll the center wheel, you can zoom in and zoom out of your drawing very easily. Okay, have a god that, and then when you're ready, the same button is also ah, hold down button so you can click with this button and hold it down so the middle button becomes pan, and you can see that by the little hand that appears on the screen when you hold down the middle button, and that means that you can then pan you're drawing side to side and up and down. Now you can do both of those operations together if you practice so you can scroll and hold down the button at the same time, which is pretty cool. Trick on. That means that you can get around your drawing really easily now, depending on where you are. Okay? Just get yourself into a nice place, okay? And depending on where you point with your mouse, that will affect where you zoom in. Can you see on pointing towards the word sheet and then I'm moving away, and then I can choose somewhere else. I'm point of these machine heads and zoom in and then assume away. So where your pointing controls, where you zoom in to on where you zoom away from. Okay, Have a practice with that. Okay, We're going to practice the pan command a bit. Mawr. Okay, so hold down your middle button and put it over to one side on. Then we're going to scroll away, hold down the middle button and pull it to the other side so you can see that all of these operations are very fluid. And when you need to get around your drawing, you need to be really fluid with your mouse. So being out of click straight into pan is brilliant. Now, if you've got the same interface as me. This is version 19. You'll see. We've got a little button bar at the side here as well, so you can see that we've got pan as a command here so you can left click that command on that, then becomes pan also, so that's a different way of getting into your pan command. And if you have a look at the same little floating button bar here, you've also got zoom extents. Okay, so if you click on that button, that's the same as typing into zoom extents, so zoom and pan on the mouse can be considered to be invisible commands. In other words, you can actually be doing something else in AutoCAD like copy or move, for instance, and you can use your mouse to usual zoom on pan. So, for instance, you might be selecting something over here to copy it over to here, and therefore you need tohave zoom and pan operating in the middle off your copy or move command on. That's fantastic, because whilst it's invisible, that means you're using it without interrupting your copy. All your move command, and this will just become instinctive after a little while. So just practice a bit more so that you feel that zooming and panning it is no big deal. Now, let's just zoom away from your drawing so just a little bit so that your, um, drawing is around about the size of a postage stamp. Now, this time, we're going to use the mouse to zoom extents with a double click on the middle button. Okay, so let's try that. So that's a double click on the middle button. And that is the same as the zoom extents option that we looked at over here. So Simic senses, let me see the whole drawing on. That's something that we do all of the time when you're working away and you're doing some details and you finish during the details and you think yourself. Okay, Now I want to see what I've done and what I've still got left to do. You can double click your middle button, okay? And that's zoom extents. Now, we can also use thes Zim command at the command line. So the command line down here, if you remember, and what we need to do is to type the commanding at the keyboard. Zed double o m. Okay, so if you just type in, said Debelo, I m like that and press enter. Then you'll see that whilst you're speaking toe order card, the command line speaks back to you. Have a look down here to see what it says and the command line says, Yeah, you can zoom. These are your options, All center dynamic extent. You can read them yourself across there all the way across to really time so you can see that you've got a number of options. So we're gonna type in P for previous on impress enter and we go to the previous zoom Whatever that WAAS and you can also type in, Zoom said. W m enter and e for extents. Enter on that soon. Extents. Now we can short cut all of those commands so we can do zoom previous just simply by typing in said into a p enter. So let's do that Zed inter p enter so that soon previous and we can short can't zoom extents as well by typing in said in tow E enter so you can see that the keyboard is extremely efficient in giving you those zoom commands now We've also got a further command that we want to look at, and that's called zoom Window. Now, zoom window allows you to choose or select on area of the drawing that you want to zoom into. It is very simple and very useful. So we're gonna short cut it again so that zed enter W and, uh, that soon window said enter W enter on Auto head is now expecting you to define a rectangle with two clicks. So here we go one corner and then the other corner. Okay, so two clicks to give you the two opposite corners of your window. Let's try that again, said into W enter on. I'm gonna zoom in here. Click, click. I'm a guy. So zoom window is a fantastic way of selecting the area that you want to zoom into. Okay, So have a practice with all of these commands on get used to him. I'm familiar with um, particularly at the keyboard. Let's go through a couple zoom extents said in tow. Ente zoom. Previous zed and P enter and assume window zed enter w enter and therefore define the rectangle that zooms you into the area that you want to look at, okay? And then I'm gonna do my zoom extents again to come out said in tow E enter so I can see the whole thing. Now the reason I've come all the way out is because I want to show you what really? Time zoom looks like, Uh, you probably saw on the command. I'm do that again, said Enter on the command line. The Zoom command says, Yeah, you can do all of this stuff. And at the end, it says, there's this thing called real time. Now when it's in those little triangular brackets, that means you can have that option just by pressing. Enter want s'more That puts you into real time zoom. And that means that left mouse click puts you into this lovely, smooth zoom, which is actually much more accurate. It's not like using the center wheel on your mouse button, and this is a lot cleaner and easier Teoh to use. Okay, so have a little play with zoom real time now, when you're finished with zoom real time, you need to right click and choose exit to come out. OK, so have a little girl that eso the short cut for zoom. Real time is zed enter. Enter. That puts you straight into real time zoom. And that means you can then practice your real time, Sam. Okay, Have a little play with that Now. You can access the pan command also while stool, uh, in your drawing, we just see him away a little bit so you can use your, ah, patent command. Okay. At the keyboard, which then produces a left mouse button pan. So if we type in p a n enter, that puts you into the pan command, which allows you to move your drawing around in exactly the same way as using the middle button of your mouse. But it's now a left mouse button operation on this particular command is not invisible. Because if you're issuing a command, then a command, the command line, uh, will override anything else that you're doing. Okay, so here we are. We've got Pan now with the left mouse button feature on toe exit that you need to right click and choose exit from this little menu here. Okay, so we've got a lot of things that we can do, haven't may. So we've got zooming in a zooming out on the mouse. We've got panning on the mouse. We've got the panning here at the side, and we've got zoom extents at the side that you can practice. We've also got the keyboard commands. PRESUME, which is zed. Enter E enter for extents. Zed enter p enter for previous. That's do said Enter P and tough a previous okay and zoom window, which is said into W. Enter so I can choose an area to zoom into. And then we've got a real time zoom, which is said into enter on left mouse click to give yourself this lovely, smooth, real time. Zoom. Okay, toe exit, right click and choose exit from the menu. Now, if at any time any of your commands get stuck or there seems to be something going wrong, press escape twice on the keyboard. Okay, have a look for your escape, but normally on the left hand top corner of your keyboard and escape is like a get out of jail free card so you can use escape to get out of any command that might have gone wrong on highways. Press it twice costs. Sometimes commands have to levels eso I get into the habit of just pressing the escape button twice. Okay, So whilst you're here in this drawing, have a little play with the zoom commands. Get used to typing in. Get used to those short cuts on DA. Then you'll be really ready to go, and, uh, we can then move on to the next video, which is all about selecting and erasing. So once you've practiced, you're zooming and you're panning Join me in the next video for selecting Andy raising. 9. Selecting and Erasing: so welcome to video number six, which is all about selecting and erasing. If you've downloaded the drawings that we prepared, then if you'd like toe open up drawing number six, select any raise on that's going to mean that you can work along with me. Okay? And if you're ready, we're gonna try and select something on screen. So just take yourself into fresh air somewhere on click. Okay, Just click once with the mouse and drag out and click again, and you'll see that we end up selecting some stuff on screen on they get these little blue grips. Now that is a particular way of selecting. That's a pre select, and we're not going to do that quite yet. But I want you to know it exists on I want you to know how to get out of it. So if you end up pre selecting anything and getting these little blue grips or want you to press escape twice, Okay, Escape is your get out of jail free card. Andi. So escape is something that you need to be able to be doing, you know, any time anything goes wrong, but something messes up. Put the command line or you You're not sure what's happening or you get into a bit of a tangle, escape twice and start that bid over again. So blue grips are very useful, and we will be covering those blue grips. But pre selecting is not the way to start off. We want to issue the command first on, then we want to select objects. Okay, so this is the way we're going to do it. We're going toe issue. The rays command on the shortcut for that is e enter. Okay, that's pretty quick. Isn't e enter for a raise and then the command line says, Yeah, you could do that, but please go and select some objects. Now, this way we're selecting after issuing the command. Okay, so we're gonna do exactly the same as we did before. We're gonna find some fresh air. Click once, bring a mouse across and click. OK, Now those two clicks means that we've issued a special type of selection window are crossing window. That means that anything that green window crosses over it will select. And you can see that now there's no blue grips, but we have ah highlighted or grade out version of our drawing so that we know what we've selected. And in fact, you can continue using your selection method to build up a selection set. That's what Autocad calls it when you've selected a number of objects ready to do something with in this case, a raise. Okay, now there's lots of different ways of selecting eso. For instance, you can just click onto objects, onder so you can actually build up your selection set just by clicking. And there is a blue window. We've just seen what the green window looks like. And now we're gonna test out the blue window. I'm gonna go over to the left hand side of my drawing click and pull over towards the right on this time I get a blue window. Okay, so ah, blue window is different to a green window. Let me just show you the green window again. Okay. This green window means that it will select anything that it touches. But when I do a blue window, it will only select something that is entirely inside the blue window. Okay, so the blue window is called on in closing window and the green window is called a crossing window. So we got crossing window there but the blue window. If something doesn't completely fill up that blue window, then it's not going to select it. I would have to go down a little bit further. There we go. There's another item that's jumped in to our blue window because now it's completely inside the blue window, as opposed to partially inside. So that's brilliant. And when we've selected these various things and we're ready to press enter, okay, it raise will take away everything that you've selected. Now, don't worry, because we're going to use the undue command to get everything back. Okay, here's the undue command. Click on that once. That's the button up in the top left hand corner with the arrow going over to the left. And, of course, you know that we've got other undo commands as well. So the windows undo commanders, control said, and the keyboard command is you enter so U for undo, enter. Now we're just gonna go a little bit further with the selection. Okay, there are different ways of holding down your mouse button, so let's start with the arrays. Command again. E enter on this time, instead of clicking for our green window, that's the green window. Then you click. OK, we're going to drag now. That's a bit different, isn't it? So left buttonholed down drag and you get this last sue. Okay, so this time you can put a last sue around the objects that you want to pick up. So if you've got an awkward shape that you need to pick up, L. ASU's brilliant. You can get a last Sue in green and blue. And so if I go to the left hand side and pull to the right, you can see I can get alas, ooh, over here on the left hand side as well. So if I want a blue window, I pull over from left to right. If I want a green window, I pull over from right to left. Okay, good to see that. That needs a bit of practice to get your head round. So there's two types of window the square window that's click and click and the last suit, which is drag and drop. And, of course, depending on whether you go from right to left it, see the green or it's blue Okay, Have a little practice on that. And when you're ready, press enter. Okay? And that will activate the rays command. There you go. And again to come back. Okay. We're gonna do and undo this time. I'm gonna do a keyboard. Undo, which is you. Enter. So that's the auto cad you enter for Undo the rays. Okay. Now, one of the things that we often find is that we get into selecting stuff and then realize that we've accidentally selected something we really didn't mean to select. Okay, so I'm gonna issue the rays command, enter. I'm gonna put a big green crossing window over here I go are no rubbish. That's picked up all this stuff in the middle. I really didn't mean to select that. So we can issue a remove command. So whilst we're still in a raise weaken type in our enter, which puts us in to remove mode, and then I'm going to use a blue window just to go over the stuff in the middle of those circles, and I've removed them out of my erasing selection set. If I then wants Okay, Good. I've saved that. Now I'm gonna add some more stuff back into my selection set to erase. I can just type in a for ad. That's a enter and I can continue adding stuff to be erased. Okay? And so I could just work around the drawing, adding stuff, and it doesn't matter if I want to use a blue window or a green window toe ad. They just behave in that different way so you can see me in selecting all of that. Okay. And then when we're ready, we've got everything exactly as we want it enter and you re raise the staff around the center. Good, good. And then just do one under here, just come back so you can practice. Um, And once you've got the hang of how those windows work, that's going to help you enormously when you're drawing stuff inside. AutoCAD being able to tease out one or two little things with the blue window is fantastic . And ah, so I'm gonna do e enter and tease out some of that stuff. Okay? So if I'm really, really careful, what I can do is I can put a blue window around here, okay? And you'll notice that I'm overlapping some stuff with the green window, and it's selecting it. I don't want that. I want to be overlapping with the blue window. Look at that. You see, Andi, Although I'm going over the big circles, they're not going to get selected. I'm only selecting the stuff in the middle. Okay, Enter toe. Activate the rays command. So I suggest a few minutes just practicing that and getting used to it so that you're completely comfortable with the way in which selection works and when you're comfortable. Okay, Then we can move on to the next video. Okay, So join me in number seven when you're completely happy with selecting and erasing. 10. Setting Units: Hi there. Welcome to video number seven on this is all about units and setting up the units within the drawing so that you know exactly how the drawing is gonna get put together. So we're gonna type in the units command at keyboard, you in I T s units, and then press enter. I am. We get this dialog box now, this dialog box is going to tell us a lot about auto cad. We're going to first check the insertion scale here, right in the middle on make sure it's set to millimeters. But before we move away from that, I'm gonna open up this list so you can see what the choices are. And you can see that I'm highlighting inches at the moment. And then we got all of these options from millimeters centimeters meters on all the way down, and you can read all the way down to the amazing light years and things like that. So it's just incredible what you can draw in AutoCAD and the units that you can apply to your drawing. However, I'd like you toe have a look at what's immediately above inches and you'll notice that you can select unit Lis on this is going to tell us a lot about Water Cat. You see, AutoCAD is a database, and in order for AutoCAD to know how to draw the items on the screen, it's got to know how to interpret the numbers that you type in. So if you have to type in 500 or 200 or 600 it's got to know that you mean millimeters. Otherwise, it would have to assume that it was a unit list roaring. You could still draw it at 600 millimeters, but it wouldn't associate it with anything. It could be MILLIMETERS. Or it could be light years or anything in between. So we've got to make sure that we get that correct. Now, the other thing it tells us is that this particular selection that you're making here is only mentioned once in the whole database right at the beginning of the database. Okay, so if you've selected millimeters, it's basically saying all off the information that comes after this is in millimeters, okay? So that when the size of an object is selected and then recorded in the database, it doesn't say 450 millimeters. It says 450 because it's already made that statement. First of all, of the top, all of the following is millimeters. Okay, so that saves a lot of space in the database, so it doesn't have to continually repeat the the unit format that you're using. Um, so not only does it save ah space, but it also makes the whole experience faster because the size of the database is directly proportional to the speed the AutoCAD reads the database. So when you suddenly get a really big drawing, if you've just got it mentioned once at the top, you can fly through the dimensions. But if it was included with the dimensions away through centimeter to centimeter, centimeters, whatever or light years all the way through, of course, that's filling up the database and taking space up in your date in your database, which is unnecessary. So once we've selected our insertion scale, do not change it halfway through, because auto cad doesn't re scale your drawing. If you've drawn in millimeters and then you suddenly change this two centimeters, it just assumes that the whole drawing is in centimeters, so you might have drawn one millimeter, and then suddenly you change over and then that one becomes one centimeter. So that's obviously wrong. So don't do it, so you choose it and you stick to it on. My advice is that once you've chosen millimeters, for instance, field Waring's, then stick with millimeters for all of your drawings so that you can easily use some of the drawings that you will make us symbols and therefore the size of those drawings that you're going to be inserting into AutoCAD will still be a predictable size. Okay, the other thing that we need to do here is we need to look at the decimal precision. Okay, so in the top left hand corner here, it does say that we're using decimals. That's true. So we're using MILLIMETERS on the precision here. The default precision is set 24 decimal places. Now you might say, OK, you know, I'm an engineer. I will probably want four decimal places, or or maybe a few more for my precision. But if you're on a building site and your builder has got JCB on a shovel, you might think that four decimal places for a millimeter is just a little bit too much, and I would agree with that. But what I'm going to suggest is this. What you need to do is you need to decide on the precision that you want on, then add two decimal places to it on, then choose that. So, for instance, on a building site, I might say, 0/2 a millimeter is plenty enough. Okay, So if I said my piece of wood was 12.5 millimeters thick, Okay, that's a far as I need to go with my timber sizes, and I can say that I've got one dismal place. But for a building site here, I would argue that you need to change this to three decimal places Now. The reason for that is error checking. So let's just say you were drawing your piece of timber and you wanted it to be 12.5 millimeters, 12.5 OK, but during the drawing process, it accidentally ended up as being 12.36 Now, if you had it rounded up to precisely one decimal place, it would actually round that up to 12.4 and Ugo, that's 12.4. I need toe. Maybe tweet that a little bit. Okay? But if you've got it set to three decimal places, you will see precisely that it says 12.360 and therefore, your girl all I actually is nowhere near what I really meant. I'm gonna have to redraw. So you've got this way of having self era checking. And in fact, if you don't have any decimal places at all, if it rounds it up to the nearest millimetre, you can have all sorts of errors hiding underneath. Um, and you need to know about those while still drawing. So three decimal places is my favorite. And also for angles as well. Three decimal places because it's really get easy to get to 11.25 because that's half of 22.5. And, um, so my own preference is for three decimal places on both when I'm doing architectural or interior work just to help me see if there's any errors creeping in. Okay, so once you've got all of that set up, you can then say OK, so down here, we're gonna click, OK? And that's our units set up. Okay. Brilliant. So if you've got your drawing correctly set up, then that's great. Otherwise, just revisit that Units command on when you're ready. Joined me in video number eight where we're gonna learn how to draw some straight lines. 11. Drawing Lines: Okay, so welcome to video number 84 drawing lines. And this is obviously a key issue as far as what cats concerned. So if you'd like to open up your drawing number eight feet below eight draw line so you can draw along with me and let's let's do this together. So what we need to do is issue the line command. It's very easy. Type the command in press enter. So l i n e and, uh, and the command line at the bottom response That's his water card saying Okay, what's next? So, lion, specify first point. So here we are. We're gonna go and specify some new points along here. Just come clicking along here to draw some lines. Okay? It's very easy. It's not difficult to or you just click and click. So you couldn't do that. But look, what happens as you draw a line, Okay? Go horizontally and you see you get this green line that comes out here. This is polar tracking. This is polar tracking, saying, Oh, I can see what you're doing. We're going horizontal. Okay? And then if we come south, you get another green line at 270 degrees south on if you come across here to the west. Yeah, water cad can see what you're doing and tries to anticipate. Now, of course, it doesn't matter if you go diagonally. You just need the dent, the length and the direction. Oh, angle. And, um but if we come back here horizontally, immediately order. Cad sees that polar tracking. Now, if you're not getting this green polar tracking popping up, let's have a look in the bottom right hand corner of these buttons down here. Okay? There's a whole series of buttons. Don't click on them randomly, but we're gonna have a look at this button here. This button is polar tracking. Okay, It looks like a clock set to 10 past three Onda. It should be blue, and it's on. If you click on it in its grey, that's off. But we wanted to be on. And when it's on, it sends out this green line which dictates, um, whether we're horizontal or vertical on the course. That's a great thing to make sure that we've got this digital set square working on our behalf. Okay, Now press enter, and that finishes the line command off. But of course, we want to be in more control than that. So we're going to do a quick undo, so that's controlled said. And we're gonna come back and we're gonna draw another set of lines. We're gonna try and draw this rectangle on the side here, So Okay, this 800 by 600 rectangle, and we're gonna do that by issuing the line command and starting over here for the bottom left hand corner. And we're gonna go horizontally, first of all. Okay, we're snapped on two Polar tracking at zero degrees. We're gonna just type in the lengths that we need Here is 800. Enter and then we're gonna come north, and we're going to do that again. But 600 this time, so make sure you got the green line sticking out and type in 600 Enter. Okay, We're on the third side now, so come back west again. Look for the green line. Okay? If you can see the green line, that's polar tracking. Giving you a digital set square. So 800 and toe, and then we're gonna come back. We're going to finish this off now. There's three ways of finishing this off. The first way is just to do 600 with polar tracking. The second way is to snap using endpoint. But the third way is just a type in close. So the autocad closes the loop. So C is your short cart. See? Enter closes the rectangle off for you. Okay, so now that we've done that, let's have another go at this diamond. If you need to practice that rectangle a bit more, just pause the video and repeat the little exercise. And then we're gonna have a girl this diamond so you can see this diamond is drawn at 45 degrees on the sides of the diamond measure 600 millimeters. So we're gonna follow that lead. Here we go. Line command. The short cart for line is l. L enter gets you straight in on the line command and we're going to click on drag roughly in the direction that we want to go for the first side. We're gonna type in 600 tab 45 enter, so that tab moves across to the number of degrees. Let's go for side too side to here we are. And bring your mouse over. So you've got a rough indication for AutoCAD to know what you're intending, and we're gonna type in 600 tab 135 Enter. I'm so the said aside because we're below the horizontal, we come type in exactly the same thing. So 600 tap 135 on. Then we're gonna come back. We've got the same three choices. We can either type in 600 tab 45 or we can use the endpoint to close or weaken. Do see. Enter on that closes the diamond off forests. Okay. And then we're gonna have a go at this other diamond. This second diamond is slightly different. The sides are still 600 but the angle is 60 degrees. So this is just going to get your brain's working a little bit harder in order to work out the angles involved. Okay, so we'll start the line command l enter. We're gonna click down here for the first point and move our mouse in the right direction. 600 tab 60. Enter. Bring your mouse up for side, too. And we're gonna type in 600 tab form 20 and then down with exactly the same command because we're underneath the horizontal 600 tab 1 20 and then again weaken clothes off in any of our three chosen methods. So I'm just going to use endpoint snap here and in time. So that's our introduction to the line command. And of course, you'll find out later that there's obviously more things that you can do with the line command. But that's the basic essence off it. Okay, you've got to make sure that you know the direction that you're going in and you issue the length. And if you need to add an angle, you tab across to the angle command. Okay, So have another go at practicing that because once you practiced enough, it becomes part of your kinetic memory on that helps you. Overall, with your learning of auto cad, the more you can do it without having to think the quicker and the better you're gonna be OK. Remember the last thing the short cut key for line is l. That's all you need to type in at the keyboard 12. Snapping: Well, here we are in video number. Line on this is all about snap settings. So in order, cad, you're allowed to snap onto elements within your drawing. And they were going to investigate that. We're gonna go beyond just the defaults, and, uh, we're gonna open up drawing number nine. So if you have a look for your drawing number VW nine, snap settings, VW nine snap settings. Get that open and it should look like this, and we're gonna have a little go at testing out. Let's snap settings So the default settings are pretty basic. We're gonna have a girl finding those down here on the right hand side. You'll see that we've got a number of buttons on highlighting the snap settings. Here. It's a square box with a little dot in the corner. You can turn them on and off by clicking on them. Blue is on, and you can right click. This little list shows you what's already currently available and turned on. And at the bottom objects snap settings gives you a dialog box that allows you to have a little look at the details. Okay, so let's have a look of these details. We've got two columns of settings, some of which detect and some of which are not. Now your first instinct might be, well, let's have them all ticked. But I can tell you now that's not a good idea. That would be too messy. What we need to do, really is we need to have the ones that we need most of the time ticked on those ones that are too powerful. We have UnTech. So let me give you an example on the left hand side, Let's go down what's available endpoint. And that's the end point off any line or the end point of an arc or a poly line. Okay, so you can find endpoints and all sorts of things. Mid points, same sort of thing. You can find a midpoint in a line or an ark or a region and a spine, all sorts of things. Okay, you can find a midpoint online, and then we've got center now centers, not the same as midpoint, because the center is the center of the circle or the center of the ark, and below that we have geometric center. So we've got a geometric center that you can apply to things like rectangles that don't have a proper center. A radi ist center. A node is a point in space on this is a point the water cad makes toe hold a position on X Y said position in space. We've got a node up here now. Quadrant is quite an interesting one, because that will allow you to select Ah, position on a circle or on arc on. That would be 12 o'clock three o'clock, six o'clock or nine oclock and then below that we have an intersection, a position where any one object into sex with the mother. So we've got some intersections here and here and here. Okay. And where two arcs cross over each other, it could be in our Coraline or align anarchist matter. Any two objects crossing over each other will give you an intersection. And then on the right hand side, we have a special snapped. This is quite an interesting one. Will practice that later. This called extension. It's a bit like a delayed or an offset position. So we're gonna have a look at that together. Insertion point. This is for text or blocks or attributes. They all have insertion points, then we've got perpendicular to. So if you want to draw a line which is perpendicular to another, you can use the perpendicular. You know, that's probably you probably realize that's 90 degrees to the object. Tangent is for linking a straight line onto a curve or a curve onto a curve to make it 10 gentle. Nearest is the most powerful of all on. It's too powerful, almost because it's any point near to your cursor any point on object near to your cursor, so it tends to override any of the other settings. The apparent intersection. So that is a perceived in section in three D. So it's not for two dimensional work is for the reader three dimensional work. And from the point of view of the screen at the time that you're doing the apparent intersection, it's where two lines cross over each other on the last one is quite easy. It's parallel. Okay, so parallel. Obviously, it's like railway lines. Okay, now we've got to choose what we're gonna turn on on what we lay. What we leave turned off on what I want you to do is have a look. It down the left hand side first fall. And as we look down the left hand side weaken, Turn on most of these on DA. We're gonna turn all but node. You don't have to have no turned on because no doesn't use that often. Andi note is found at the end of things like dimension lines on. Unless you're specifically putting nodes in, you're not gonna need a node. Now you'll notice I've no ticked any of thes on the right hand side except for extension on . The reason for that is that they can actually get in the way wall stored roaring. So, for instance, nearest is so powerful that you will get nearest before you get anything else. So it's sort of tends to override endpoint in mid point because the nearest point OK is gonna be the point nearest to the object you're pointing out. And, ah, the other items like, for instance, tension and perpendicular can also jump up when you're expecting to find things like endpoints and midpoint. So it's a little bit difficult toe. Have those turned on as well as everything else. So it's a great idea toe only call up the ones on the right hand side when you need them and you can call those up with their 1st 3 letters. For instance, P er gives you perpendicular tiene gives you 10. Jim, Any a gives you nearest onda. That's actually brilliant, because when you call up those particular shortcuts, what you're gonna find is you only get the one that you've called up. You don't get any of the others. So if you look at your drawing, you think I must get that whatever it might be that say it's a node and you want to call it up and O. D the only thing you get is a node. And even if you've got something ticks like center of circle, you can choose to type in CE n toe force auto cad toe only. Look for a center of a circle and in a busy drawing, of course, that makes the whole thing a lot easier. So let's just check out tick boxes, make sure there as we have here on, then we can say, OK, when we can start using, uh, our snaps by drawing some lines. Okay, We're gonna have a girl, a line command with all of these snaps turned on. So if we start the line tool L I N e at the keyboard percenter and we hover over one of these circles as you hover over this a conference, you'll see that we get a little cross in the middle that shows us where the center of that circle is, and then we can hop over to the next circle and you'll see another little cross that shows you where the center of that circle is. So we do center to center. But now we're gonna go for some endpoints. Okay, here we are. We've got endpoints here. That's a little green square that you can see when you find the endpoint using Just wonder from endpoints endpoint Connecting together. Now here, you'll see that didn't quite work. So we'll just do you enter, make sure we're gonna haul the right over the end point. I mean, click. So now we're gonna go for into section now. In fact, if we go over here, you'll find that not only do we have an intersection, but we also have a midpoint at the same place. So, in fact, midpoint shows up first here. So we can click on that. We can come across and we're gonna find another intersection is to ox the insect. So we're gonna click on that. You'll see that the intersection is a green cross up here. We've got both an end point and a quadrant. Now the endpoint shows up before the quadrant. OK, but over here, we've only got a quadrant. Can you see? It's a green diamond So we're gonna click on the green diamond But you can come back in section and then we can come back over here toe into section Now we've also got the geometric center off a rectangle that you can see here We've got a rectangle And we got a star in the center for geometric Center where you can click on that Then let's see if we can get a tangent to this circle Okay, Now we want a force A tangent with ta en in tow tiene enter. There we go. We found the tangent critical mass that you can see. The tangent is not quite at the same place as a quadrant. Okay, on the circle, that's just a little bit out from there. So this shows us that our snaps are working. Well, we can go for a midpoint here on this line on a midpoint here. Okay, so let's have a little think as you're going around, let's see if we can get ourselves a perpendicular to Okay. Now, if we start to go perpendicular to this line, we only get intersection. But if we try perpendicular to that one, we're gonna need to force perpendicular, which is P e. R. In tow. And then, as we go for particularly in, see that little green right angle triangle. Then we go and click onto that. So have a little one around, See if you can find any other little snaps you want to snap onto. So here we are. We got a node in o D enter and it will pick up the node. Let's pick this one up over here as well. So you can see and a d enter we go is your node, and you've got plenty of opportunity to pick up all sorts of different snaps on this busy drawing. So I give it a little play and then see what you can do. Okay. Now, while still drawing most of the time the snaps will be a good thing. Onda. We can start drawing and pick up, let's say, a quadrant. But there are times when, for instance, you're trying to draw Ah, horizontal line. You're relying on polar snapping off polar tracking that you don't want any accidental overrides from any snapping. So whilst you're doing that, you compress F three F three temporarily terms off your snap mode. You can see we're not snapping on toe anything now when we can just draw our ordinary straight line. And then if we want to come back to snapping with press F three again on that terms, they're snapping back on. You can see now that we're getting snapping, okay, popping up there so F three is an invisible command. In other words, you can do it whilst you're in the middle of something else. So f three and you'll see on the command line. It says Snap off and then f three. It's a snap on, so that's enormous little toggle that you could do in the middle of drawing lines or circles or squares or what have you want to do? Okay, give that a go. Have a bit of fun 13. Drawing Rectangles: So you may have guessed from the name off this section rectangle that that's the auto cad Command, which we're going to be using to create a rectangle So we'll do some practice. Freehand rectangles, first of all. Okay, we're gonna type in the short cut R E C on the you'll see on screen. We've got our e c brackets rectangle so you can see the shortcut on Did you can see the whole command press? Enter Andi literally by clicking in the bottom left hand corner on, then the top, right and corner opposite corners. You can draw a free hand rectangle. If you press enter, you can repeat the command. And that's true for any command. So enter will repeat the last command you did. So we can then do opposite corner tow opposite corner in tow, opposite corner tow opposite corner. Okay, so it's pretty easy drawing freehand rectangles on. You can practice that as much as you like, and then we're gonna do some undoes. So I'm using controls. Ed controls their control, said, and now we're going to draw some rectangles with a bit of control. We're gonna draw the 1st 1 okay. On the left hand side. So, Ari, see, Enter is your speed key. We're gonna go for here to draw the rectangle, and we're gonna type in the two dimensions the 601st coma and then the 1200. So 600 comma 1200 enter. Whenever you finish typing, you must press enter because otherwise, autocrat doesn't know that you finish typing. Andi, if you're doing horizontal dimensions, okay, you do the horizontal first, followed by the vertical because it's the X axis first, which is left to right, followed by the Y axis, which is up and down. Okay, so that's a pretty straightforward, easy rectangle to draw. So we're gonna try the 2nd 1 Okay. Different dimensions bar. You follow the same rule you always do. The horizontal dimension first, followed by the vertical dimension, so exacts its first, followed by y axis. So let's try that again, Ari. See, enter. Click for the bottom left hand corner. Moved the mouse so you can see roughly what you're gonna get 1000 comma. 600. Enter now. I made a typing mistake there, so I didn't get the full 600 did I? So s o. I didn't get the full 1000. I'm gonna do a control, said Ari. See, I'm gonna try again. Click May've 1000 comma 600. So that's a common mistake, really, That I've just made there. When you're typing in a number of zeros, just check the number of zeros that you've used because you get a little bit but of bounce on the keyboard and you think you've typed in three and you might only have two or you might have four. Now, course, if you are making errors, you want to self era check. So I'm gonna show you how to check the size of your rectangle after you've drawn it. If you just click onto the rectangle and you hover over the top left hand corner, you'll see the AutoCAD reports back to you the size of the rectangle you've drawn on. There we go. That's fantastic. To get rid of those blue grips, move your mouse away, press escape twice and we're back into drawing. Okay, lets try the thin the long thing rectangle at the bottom. Gay that 1600 by 66. And remember, the same rules apply. The 1600 comes first and the 66 comes after a coma, So we'll type in the short cut Ari, see enter, click for the left hand, bottom corner and pull away. We're gonna type in 1600 comma 66 enter. And there we are. We've got the rectangle that we wanted. Okay, Last little exercise. Here we go. This is a portrait arrangement as opposed to a landscape, but the same rules apply. Ari. Si. Click pull away. 401st coma. 1400 inte. Okay, It's pretty straightforward is now. Now, you can also draw rectangles that go down as opposed toe up. But when you have the dimension in the Y axis going down, it must be a minus different dimension. So we're gonna hook the next rectangle onto the top right hand corner of the rectangle that we've just drawn using endpoint snap. So here we go, Ari. See? Enter. Find your end point. Snap and click on it. Pull down in the direction. You're expecting this to go on. We're gonna have a rectangle which is 600 by minus 600. Okay, so 601st coma minus 600. Enter. Okay. So you can see this square because it's 600 by 600 goes down from the point that you clicked as opposed to up from the point that you clicked on. So it's a minus y Okay, so of course, you could also do minus X and minus y if you wanted to. So let's try that. We're gonna do 600 by 600 again. So, Ari, see? Enter and we're gonna come over into this corner, click and pull down in direction. You're expecting minus 600 comma minus 600. Enter. And you could see the direction now of the rectangle relative to the point that you clicked . Okay, that's great. So we've got a nisi way of drawing rectangles. We've got a protocol which means X axis first, followed by the Y axis. We can decide whether the rectangle is going up or down by which of the two dimensions we decide are gonna be minus, and they can both be minus. The other thing we can do is self error checking so we can select the rectangle hover on the corner, and AutoCAD declares the size. So that's good on the last thing that you need to know is that once you've golden rectangle , you can hover onto the corner of a rectangle and order. Cad will tell you what it is, and this one is made with a poly line. All rectangles are made with poly lines. And if you hover, you can see that might well, hovering right on the edge. And this means that the whole rectangle is one object. So that makes it very sensible. Easy to use, easy to copy, easy to move. And, uh so we're to expect the all rectangles as they're constructed our poly lines. Now, we haven't done much with poly lines, but we're going to in some of the future videos so we can cover that detail. Have a little girl drawing some more rectangles. If you like. On once you've got the hang of it, we can move on to the next stage. That training 14. Drawing Circles: So here we are in video number 11 and this is all about circles. So you might want toe open your drawing V 11 circle. Okay, let's get that open, and you can follow me. Good. So what you'll notice is we've got some examples at the bottom, and we've got some squares at the top of some rectangles atop toe. Help us with drawing circles every time we add. Ah, detail into our drawing were making it relative to other things in the drawing. So we're using some rectangles to help us make the circles relative. Okay. And, ah, we're going to be drawing a simple circle first. Okay, on the left hand side, we're going to use the command, which you can guess from the title off. This video is circle, so type in C i r c l e enter. And we're going to use the center of the cross here on the left hand side. So find there's a endpoint in the middle, click and then pull out for your radius. Now, you could make this circle any size you like. Really? But if you have a look at the example underneath, we've got 475 is our radius, and all you've got to do is type that number in 475 Enter. And there we are. We've got a circle That's the same radius is the example below. Okay, circles pretty easy on me. But there's a number of different types of circle that you can draw. Okay, They're all circles, but you can construct them in different ways. So if you look at the title at the top here, we've got a two p a three p and a TT. Are these Airil different methods for constructing and we can have a look at those different methods by starting the circle command. Your short cut for circle is see, So that's a nice, easy shortcut to remember and then have a look at the bottom here where we've got the command line. Okay, you may have your command line somewhere else because you're allowed to move it around the drawing, but at the bottom of the drawing here it says circle specifies CenterPoint, which is the 1st 1 we did or three p two p. T tr. Okay, so a three point circle is one that where the circumference is defined by three points. A two point circle again is very similar to a three point circle. But because it's two points, it must be the diameter on. Then the last one is T tr, which, as you can see, is tangent, tangent radius. And that's a nice special circle. And we'll have a look at how to draw that. So the first circle we're gonna attempt is called two P. So that's two points on. We're going to use the midpoint on the top of the rectangle and the mid point at the bottom of the rectangle to define the diameter off our circle. Okay, so here we go. We're going to choose to pee. I'm gonna type that in to pee enter. We're going to go for the top middle point on a rectangle click and then the bottom middle point on a rectangle, and you can see we've got a circle. It's designed to fit that rectangle. The diameter is 600. Therefore, the radius is 300. Okay, so now we're going to do a different circle using a similar size rectangle. This time it's gonna be the three point circle. So we issue the command in the same way that see enter. But then we follow up with three p enter. So the AutoCAD knows our choice. And we can choose any three corners on this rectangle to define the circle that fits precisely to that rectangle. So you're doing an endpoint snap on each corner just to make sure it fits perfectly good. So that's a two piece circle, a three piece circle. And now we're gonna do a T t r. So this is easy again. See for circle enter. Then type in T T t o. And we're gonna pick up the tangent on the left hand side, off a rectangle kick on that and then the tangent at the bottom on the bottom of that rectangle. Click on that. Okay. And then it says on the command line, what's the radius? And we're gonna answer 300. Okay, so it's worked out where the circle would fit onto the two lines that you clicked. Now, we could do that in a slightly different way. OK? By changing which two lines we choose, the circle will move. So let's try that as well. Okay. We're gonna do it again. See enter t enter, click on the top and click on the right hand side on. Then type in 300 and you can see the circles moved. Now we're gonna have a little bit of extra fund because if I tell you that water cad remembers the radius of the circle that you've just drawn right, we can use T tr in one of the other rectangles that we've got here. And instead of having to type in the 300 when we get to the radius bit or we've got to do is press the enter button. So let's give this one a go see enter T enter on this rectangle. We're going to click on the bottom and on the right hand side and then just press enter. So remembers that the circle radius was 300 and it draws a circle to fit the parameters that you've defined. Okay, so that's the end of our little session on circles. Onda, we're going to move on in the next video on, have a look of arcs. So see in the next video 15. Drawing Arcs: Well, welcome back to video number 12. This is about arcs. And so if you want toe, grab the drawing that we need. Okay, you'll find that it's a V 12 drawing number V 12 arc. Get that open and you can draw along with May, and we can find out how it really works. The Ark Command. As you can see, a r c, we can just type in here i r c enter and weaken stopped by clicking any way you like on three clicks produces on arc. Of course, we need to be a bit more in control of that. So I'm going to do an undue using controls ed on on the left hand side. I'm gonna copy this arc we've got on the lower left hand corner and we're going to use this rectangle that we've got to help us control the position of the Ark. As you could see at the top here it says three p and that's the default setting. Three points on the Ark controls where the art goes. We're gonna try that with a shortcut. The shortcut for Arc is a so that's a enter and we'll start here on the left hand side. Click up to the top, find the endpoint click and then come down here. Okay, Find the endpoint. Okay. Brilliant. And that's created a three point arc. And if you want to check your work, you could hover all of that. And it says, Arc, you can click on it and then hover on one of those points there and you'll see that we've got of 475 millimeter radius. Okay, just check on that. You get 475. His brilliant escape escape. Okay, the second dark we're going to do is called center start end on. This is the construction methods. So here we are sent to start in. So we're gonna draw the ark in relationship to this rectangle here, and we're gonna issue the short cut A for arc. Okay, that's a enter and then on the command line, have a look in brackets is says one of the alternatives is center. Now, that's what we want. So we type in c enter, go for the mid point on the left hand side here, look for the green triangle and click on it. Come down to the bottom left hand corner. Okay, click on that. And as you start to draw, can you see the ark is developing as you move your mouse over the to the top left hand corner. Click on that and we've created the next arc. So as this construction method says, you can see it's his center. Start end. That's what we chose. Okay. To remind you of the way in which we got there was a for arc. Enter. See for center. Enter. Click for the midpoint. Click for the start. Click the end. Now that was pretty straight forwards. But what I want to point out was something else. When you constructed the Ark as you constructed it from start to end, the drawing of the Ark was anti clockwise. Yeah, Antico eyes. Now that's because auto cad decides to draw the Ark anti clockwise first. That's its default way of drawing. Now, if we wanted to switch that around, we couldn't do that. Okay, so let's have a go. Let's repeat the same command. I enter, See? Enter. We're gonna do it on this side of the rectangle. We're gonna click the midpoint. Okay? We're going to go down here to the start point. But of course, we want the direction to go in the opposite direction, so I'm gonna hold down the control. But this means that I then start to draw my arc clockwise, Click on the end point, and then I can let go of the control. Okay, so now we've got a method of drawing arcs in either direction. The default is anti clockwise, but control allows us to draw clockwise. So let's move across to the third method. The third method, as you can see here, is center start angle. And in this case, we're going to use the angle of 56 degrees basically, because it's quite random. Okay. Okay, here we go. We're gonna do this together. You ready? Yeah. Good. A enter for arc, see? Enter to start with our CenterPoint, click in the bottom left hand corner. That's our center point for the ark. Okay, then here we're going to choose. The midpoint of this line is our starting point. And as we come up, you can see the line is getting drawn anti clockwise. But all we've got to type in now is the angle. So that's 56 degrees. Enter on. There is our arc. Okay. And the radius of the ark is controlled by the distance between the center point and the midpoint, which was 500 in this case on the lens of our ark is controlled by the angle, which in this case, was 56 degrees, or whatever angle you want to type in. Now there are many different arcs that you can draw so many different arcs. It's just unbelievable. And I want to show you that up in the top left hand corner here we have a list of all the different types of arcs. Well, not even all of them. Some of the different types of arcs that you can draw with Water cat, starting with the three point arc, which is the default. Okay, that way we tested out here. And then, of course, the 2nd 1 which is start center end, which we've already tested out. But then have a look down. This list on this isn't the whole. This isn't the end of it, okay? There's all sorts of different ways of drawing your ox. So what I'm gonna suggest you do is have a little play withdrawing ox. But down in the corner here, I just want to point out one thing. You can't draw an arc, which ends up being a circle. Okay, if you try to draw an arc that starts where it ends, an AutoCAD goes now. So if you want to draw a circle, you've gotta draw a circle. Okay? If you want to draw an arc, which is part of a circle, then choose the Ark Command. All right? So brilliant. I enjoy having a little play with this Onda. We'll meet up again in the next video. 16. Drawing Polygons: So here we are in video number 13 Polygon. So if you like toe open your drawing and we can work together on this. Okay, Uh, and you can see that the AutoCAD command is called polygon. Polygon is like a hexagon or an octagon or a triangle or a square. So let's have a go at drawing some of these. Each of the operations is based, assuming that you're going to know the radius off your polygon. So we're using a circle toe. Help us to understand how that works. Okay, so we've got a serious of red circles top here, and we've got some examples at the bottom. So we're gonna do the very obvious one first, 26 sided polygon. So all we gotta do is inside AutoCAD. We're gonna type the command P o l. Why on as your typing, Polly, you'll see that you get various options. So let's continue, G uh, n polygon. Okay, enter and then enter the number of sides. Have a look at the command line. Every time you issue a command and press, enter the command line, speaks back to us and says, what? What? God needs next. So enter the number of sides on we're gonna say six. Enter and then the command line says, please specify the center off the polygon. Okay, so if we hover on the radius off our circle on the circumference of the circle, we get a little white cross in the middle over there. The green snap. The circular green snap says we're in the center. Click on, then answer the next question. So the question is, is this inside the circle or outside of the circle on AutoCAD Says, is this inscribed or circumscribed? Okay, so they're the mathematical terms, but my term is is it inside circle or is it outside the circle? So we're gonna go for inside the circle, and then as we move our mouse, you can see we've got six sided polygon. Okay, Is it? So you are that standard hex head screw and a bolt, and we're gonna go to the 12 oclock position and click. Okay, So there's our standard six sided hexagon and ah, it's pretty straightforward, isn't really once you see how the command works. So let's move on to the next one and eight sided Octagon. So we'll start the same command Okay, so you'll notice that the short cut key is p o L for polygon ente. Choose the number of sides, which is eight in this case. Find the center of your circle and click Choose, inscribed or circumscribed. OK, so we're going to do this one outside of the circle. So here, we're gonna choose circumscribed outside, and then we're gonna go back to the 12 oclock position and click. Okay. Very straightforward. Says now. Okay. Hover over the edge of your octagonal your polygon, depending on how you want to describe it, and you'll see that it's a poly line. Okay, click on it. And AutoCAD reports back the size off each lentz off the polygon. Great. So we're not getting a radius. In this case. If you want the radius, we can select the circle, right? And the circle radius will be given to us. Hey, escape escape to get out of that, let's try this triangle. Okay, So the triangle, um, is the drawing said inside and circumscribed. Okay, So here this swamp inscribed is gonna be the smaller triangle. And the circumscribed one here is gonna be the bigger triangle. Can that strike again? So p o l. Ente Number of sides three. And we're gonna pick up the center. This one is inscribed, and we're gonna pick up here we are and go around and decide. I'm gonna pick the three oclock position on DA. That's pretty easy on The big difference is if you choose a circumscribed triangle. Great, that's outside. So we'll press enter to repeat the last command will press enter to accept three sides again. That's because old cat can remember what you were up to. We'll find the center of the circle and choose circumscribed. And this time we're gonna choose the nine oclock position and you'll see how easy it is to draw, um, a triangle using the polygon. Okay, so let's do a couple of undoes and practice that. So control said controls. Head control said Control said, Okay, we're gonna work through that again together, so p o. L. Ente number of sides six. Enter. Find the center Click inscribed 12 o'clock. Click. It's pretty quick, isn't so. Let's repeat. Enter right and, uh, find the center click circumscribed on this one. Okay, again, find the 12 o'clock. So there's our octagon. Enter three sides inscribed Okay, so answer three. Enter. Find the center inscribed. Okay, We're gonna choose three o'clock, and then we're gonna do the last one again. Enter. To repeat, enter for three sides. Pick up the center. Here you go. Answer the question. Circumscribed. Okay? And we're gonna go to nine o'clock and click a guy. So if you wanna have a little bit more practice and choose different sides to your polygon , you could do four sides. You could do 12 sides like a new pound coin. You could do 147 sides. If you really wanted to know. I'm recommended it, but it's possible you choose the number of sides. Okay? Have a little guy enjoy myself, and we'll see you in the next video. 17. Drawing Elipses: and we've arrived at a video number 14 on this is all about the lips. So open up your drawing, which should be number 14 v 014 lips. Okay, We're trying to make it easy for you to follow this and you can work alongside. So the command that water card is expecting, as you can imagine, is a lips. Okay. So, weaken, type that in. I'm gonna type in e l. And you'll see on screen that e l is the short cut for ellipse. So that's a nice, easy shortcut to remember. Press, enter and follow the command line. Phillips, specify access endpoint. Okay, now, on the left hand side, we're going to use a rectangle first of all to help us to draw our lips, and we're going to start at the midpoint on the left hand side. So we click on the midpoint of the left hand side, come right the way across to the right hand side in the mid point on the right hand side as well, and then we're gonna come up to the midpoint at 12 o'clock if a rectangle can have 12 o'clock. Okay, so there we go. So that was just midpoint. Midpoint, midpoint and our lips fits our rectangle perfectly. It doesn't have to be a landscape. You can do a portrait version of that. Let's try that again. E l Enter. Start at the top, come straight to the midpoint of the bottom and then come out to three o'clock. And then we are. We've got our ellipse, and it's one of the most beautiful things that autocad drawers of its own volition. So that's one way of drawing your lips by incorporating into a rectangular a control box. But that's not always available. So I want to show you what happens or how you can control your lips eyes with just having the access and the endpoints. So we're gonna draw this again, E l. All right, and have a look on the come online on. One of the options is center, so to see and then presente, here's the center. We're going to click on it, then you'll see it on the command line. It says, Where is one of the main access endpoint? So we're gonna go to the end point here on the last one is Where's the other access endpoint? Then we're gonna come up here and click. There we go. So that was pretty easy to now. At the moment, all of our ellipses have bean either horizontal or vertical. So you might be forgiven for thinking that's the any type of ellipse you control. But it's not. Any angle is acceptable, so we're gonna just try exactly the same as we did just now. But at this cranky angle or it So that's e l enter. See for center. We're gonna come to the center point here up to the end point and then over to our second endpoint. Quick. Okay, that we got four different ellipses, okay, on all associated with existing geometry. So you'll recognize now that all of these complicated shapes need a bit of construction, which is why you end up putting your construction lines in. And then obviously, if you want to erase or hide your in your construction lines at a later point, then that's perfectly all right. So why don't you do a few undoes on practice those ellipses so that you can feel totally confident And then I'll see you in the next video 18. Intro to Polylines: Okay, So welcome to a new video about Poly Lines. This is video number 15. So if you'd like to go on, open up your drawing V 15 y p line. So Polly lines are amazing and poly lines by the name are many lines joined together. Poly many lines, many lines on their joined together. So, for instance, if we had to have a look at this rectangle, okay, and I'm going to click on it, you'll see that the whole rectangle is a solid rectangle. So that's four sides. Four lines joined together. But if we were to have a look at something else we've got circles, arcs and lines all joined together. So you can see Here we go. We've got a more complicated Polly line and then down over here, we've got on open poly line. In other words, one face, one edge is no connected up. Okay, Now you can have arcs on parts of circles in your poli line, but also, you can have a more interesting shape of mathematical shape. This called a cubic curve, and we're gonna go have a look about that in a minute. But in the top left hand corner. Let's have a look at this one. We've got a industrial application here. This is a cam on a follower. So this is the follower up here on down below. Here, this is the cam. This rotates around our central access on the follower follows the top edge of the camp where it touches. So as this turns around, we can have a different distance from the center for the cam to follow on. These red lines represent the distance at a particular angle. And therefore, if you join these up and I'm just going to select the poly line here, you can see that we've got the poly line connecting up those points. And we have a particular mathematical solution that runs all the way through that. Okay, so we'll be discussing how to create, uh, curves that run through points. If we have a little look down here, this is ah, more simple arrangement. But if we started off with a shape like this every time we offset it internally, it creates these shapes. And AutoCAD works out the changing radius as we go in closer and closer. So I'll just show you that one. We're gonna do an offset through. I'm gonna select this one. If I was to go in far enough, it would lose the radius and you see that radius start to lose. And as we come out a little bit further, we start to get a bigger radius going depending on where you decide toe offset to what you click on as to where the offset sets or resides. Okay, so that's nice way of using poly lines. This one shows you that you can fill it Upali line and get all of the corners in the poly line. Fill it'd at the same time. So that's a pretty neat trick. Saves you, but a time. And then over here we've got a way of offsetting and again it follows the shape. Now this one is all neat and tidy. But up here, you can see that I've offset so far that we start to break up. Let me just show you with this one, we do an offset and through as you start to get in. Can you see? It starts to break up. AutoCAD will guide on arrange exactly how that's gonna work. Okay, It's pretty neat. Is that so? good. So order card and poly lines on offset and sickness, as you could see. Or as AutoCAD calls it, the wits of the line. If I have this one selected, I just make sure it's got grips on. We get in the properties of the side here, we can see start segment with 50 end segment with 50 global with 50 global with 50 is the thing that's changing and altering this particular line at so five, for instance, changed the global with 2 25 You can see it would be sinner. Good. Okay, so I'll just press escape and then zoom extents. So that said, Enter. Enter on. We're back to the beginning. Good. So have a little look at those poly lines. Hover over the lines and you'll see that there poly lines click on the lines and you can see the grips that hold them into place. Okay. And then we're gonna find out how to make poly lines. Onda how Toe edit Polly line. Okay, so when you ready, we'll see you in the next video. 19. Pline and Pedit Commands 1: So here we are in video. 16 all about poly lines and using the the line command and the Pettitte command. Okay, so there's two ways of making poly lines. One as we're gonna have a look at here. We've got very simple lines, just ordinary lines that we have drawn before. This is three of them here, one to three. Okay. And we joined them up to make on overall Polly line. Okay, so there's one object here called Upali Line, and we use the Pettitte commanders. We've got written down here to join ordinary lines together. Okay, so we're gonna have a little girl doing that. We're going to start off with the water cat command Pettitte P e D. I t enter said typing on the keyboard. And we'll select one of these lines. And then AutoCAD says, Do you want to turn it into one? In other words, you want to make a poly line out of this? Yes. We get this little menu. So now that we've got this little men you were going to say, join everything together, that here we go. We're going to join this one to that one, and then that one press. Enter on, enter to finish. Now. If you hover, you'll see it's one object, and it's now a poly line. That is pretty simple, wasn't it? And this is an arrangement. This is, ah, command that we use a lot. So it's worth getting hold of this particular skill. Okay, and we're gonna repeat it. But this time you will see in the example down here if we hover, it says it's a poly line, and it's a closed polly line. But this shape is an open rectangle, but one side missing, so I'll show you how to use Pettitte to close it off. So P E. Is your shortcut on press center. Select the 1st 1 This is not a poly line. Do you want to turn it into one? Yes. Press center. Join. Select the parts that you want to join together. I'm Press Center now. This time, when we look down here, one of the options right at the top here is close. Pick on that. It's closed the whole thing down. Press enter to come out and there we are. We've got a poly line and it's closed. No, over here, you'll recognize this maybe from the last video that we were in. We've got a poly line here with the wits and it's got Phil. It'd corners. So we're gonna go through not only the Pettitte command here, but we're also going to go through the Philip Command just for this. We're gonna do fill it again later. But just because it's interesting and it's relevant to what we're doing, we're gonna go through the Filic unplanned as well. So here we go. P E is your shortcut for Pettitte. So p e on the keyboard and enter pick up one of the lines that we're going to create. Do you want to turn into one? Yes, Percenter, join them together just like we did before. Select all three and in tow. And now this time we're gonna change the wits. So we're gonna choose the wits option on type in 25. So that gives us a global wit and then press enter to come out of that. So we've use Pettitte to create the basic shape. But now we want the corners rounded off using the Philip Command, and you can see from the notes we use fill it, then set the radius to 90 on. Then tell order card that it's a poly line with the P. Okay, so let's do this. Fill it. F I double l e t in tow. Now, the radius by default would normally be set to zero. So we're gonna have to type in our enter 90 enter to set it to 90 and then because fill it isn't yet expecting a poly line. We have to type in p enter to say, this is gonna be a poly line. Hover over the edge here, and you can see both corners will be Phil. It'd at the same time. Good. Now, up to now, we've used existing lines with the Pettitte Command to create a poly line. But you can draw a poly line from scratch using the P line Command P L i N e. And we're gonna trace over this ghosted line here. Click, click, click, endpoint to endpoint. Okay, on entered to finish. So now if we hover over this one, you'll see it's a poly line on. We can edit this Polly line with the Pettitte command. So the short cut for Pettitte is p e enter. We can click onto the poly line to select it on down here, you can see that we can choose to make it into a spine and enter. So there we are. We've got a spine, reflects what we've got as an example below. But if you select, that's plein down in the properties that you may have open. If you haven't got it open, then I'll show you how to do that. Right Click and then properties, Okay, that opens your properties Dialog box on the bottom. Under miscellaneous, you've got your curve style, so none would put it back to where you started. The fit curve is pretty crazy. That allows the curve to point to run through the points that you'd delineated with your straight lines. The quadratic is one particular type of mathematical solution. Uh, which is 10 gentle at the center point of each of the scent segments on Cuba is a different type of mathematical solution which runs through the center points off each of the segments , except for the first and last. There we go. That's the poly line. That's a great introduction on will be doing more work on poly lines later 20. Pline and Pedit Commands 2: Okay, Welcome to video number 17. Still talking about Polly Lines because poly lines, that's so important. So if you'd like to open up your drawing 17 p line on, then you'll see what I can see. So Polly lines are really important. And that's why we need to get a grip off the whole command. And we're gonna have a look on the left hand side as to how to draw that camp follower. First of all, if you look at the one below you'll see, we have this shape, the egg shape, which is a two D polly line running all the way around. Following those guide points, the red end points on these lines. Okay, so we've set up the construction here, and we just go through the important bit. We're going to use the P line Command on the shortcut for that is pl so type P l enter on your keyboard. We're going to start at six o'clock. Click on the endpoints. Be very careful as you're going around to make sure you get endpoint, make sure it's in the right place. Okay. And then when we come around to this point here, we're not going to finish off. We're not gonna close off the poly line. We're going to just leave it at that. So enter to finish with that open section. And the reason we've left one section open is because we're going to use the Pettitte command to close that off. So we're gonna type in the short cut for Pettitte, which is p e. Enter. And when it says select Polly line, we're gonna click onto the Poly line like this, and then we're going to choose the clothes feature which closes the poly line. Okay, so now we've got all the 123456 sides. Now we want to make sure that the curve fits als the endpoints, So we're going to use a fit curve. And there were There's our egg shape and enter to finish. So the important thing here is that not only did we start by drawing the poly line, but we didn't close off the last segment. I'm We used Pettit to close that off to make sure we had a continuous mathematical solution running around the whole of the camp follower. Okay. Over over the top here just to make sure It's a polygon. Obviously, is going to be, But they are too deep Ali line. And that's a camp follower. Now, in the next, um, example down here, you can see we've got a whole bunch of rectangles which were drawn again up here. But you can see that we've got varying widths. And if you were to select them, you'd see the wits in your properties. Okay? Global with 50. Now, I've listed the wits that we're gonna go for up here. Pettitte Wits. 50 for the out 1 25 and one. Okay, so it's 50 for the outer 1 25 and one. So we're just going to use the Pettitte command to do this ped enter. Click on the outer rectangle. Wits 50. Okay, enter to finish. Now, if we use the enter button immediately after the Pettitte command, it will jump straight back into Pettit. So that's like a repeat command. Click onto the line. And again, we're going to do wits, okay? And the wits is gonna be 20 and to to finish enter to start it again, click onto the line wits five, enter and to finish and just start Pettitte again. Click on the line. Wits one. Enter. Enter. Now. Depending on the quality of your screen, you'll notice that there is a difference between no wits and a width of one. And you'll see that, particularly when you start to zoom in. Right. Good. Excellent On. Then. Let's have a look at the way in which offset affects your polly line. So at the top here, we've got one Polly line all ready to go, and we're going to use the offset distance of 90 toe offset. This so we're gonna type in the command offset at the keyboard. Okay, Odubel F s C T press, enter, and then it says, Please specify the distance. We've suggested 90 here, 90 enter. Click onto the poly line and then just come outside and click again and you can see that Easy to get an offset. Now we're gonna go on, do an internal offset as well. So click on the original Polly line on, Come inside the shape and click and you can see how AutoCAD works out The new internal, uh, shapes and radius is let's do it again. And this is where order card starts to cut off the various shapes. Oh, isolate on da again. We'll do another 90 offset. And you can see it works out this beautiful arrangement based on the original poli line that we had. Good. So enter to finish that command. And you're starting to get to be Polly line experts Have another go at those commands. Maybe work through the exercise once more. It's just so that you've got, uh, the idea firmly in your mind, okay? 21. Exploding Polylines: Okay. Welcome to video number 18. This is all about exploding poly lines. So if you want to open up your drawing number 18 p line explode on, then you'll see what I can see, and you can work along with me. Good. Okay. So you know already by the videos that we've already done that when you make a poly line, you can make it from ordinary lines and curves and arcs and things like that Bring them together on May Kapali line. Now you can do the opposite. You can take the poly line apart with the explode, but you can just explode it back to its original components. But sometimes the components don't go back exactly as you might expect on de, so you can get some solutions which aren't quite so obvious. So let's have a look at some of those now. We're going to use the command explode Onda. It's pretty easy to use, but I want to show you the results off the explode so that you can see what we're going for . So up the top here, this looks very much like the poly line that we've got at the bottom, but it's No, it's actually on exploded. Polly Line. And if you zoom in here, you can see that the poly lines made up of little bits. Whereas down here, the original Polly Line guy is as we would expect so the top section are exploded poly lines. So have a look down here on the circle instead of getting a circle. We've got a number of quadrants. Okay, that Allow us to see the poly line exploded. Okay. Again, you can see that. We've basically got, uh, on arc. Okay. If I select each one, you can see it. An eighth of the full circle. So there we are. Holly line there is actually exploded into a number of little arcs on in the middle here. We've got what? Waas, a thick line with a radius Great on that's being exploded into single lines on arcs. Okay. And then we just have a look here again. We've got a complete rectangle which has bean, Phil. It'd on all four corners, and here it just series of lines and ox. Okay, good. So let's have a go at the command. We have a short cut for the explode command and the short cut is just the letter X on the keyboard. Okay, so that's X enter. We can click onto the example of the bottom, which we know is a poly line presente. It doesn't change very much, but when you select it, you'll see that it's now a Siris of tiny arcs. So let's go and check the rest out the next one. Here, you could hover onto it, and it's a poly line. We can type in X, enter, click on to it and press enter on. Once we then check it out. It's back to its constituent parts, just like the example at the top here. Okay, what about the one with the wits? Let's have a guy x and toe. Okay, select it and press enter. And there we go. It's lost its wits and it's lots of different bits. Okay, It's now segmented into various different parts. Okay, the last one looks like a circle, but in fact, what it waas was Upali line drawn as a square and then converted into a fit curve. And because it was a square, each side now is exactly the same size curve. So therefore it looks circular on. We're going to explode it. So that's X. Enter on the keyboard and enter, and you'll see that Here we are. It's made up now of Little Arc SEC segments and is two per quadrant. Therefore, there's eight for the whole circle. Okay, have a little play with those. And if you want to reload the drawing, you can have a go exploding them all over again just so that you get confident with selecting and exploding. Okay, well done. And we'll see you in the next video. 22. Polar Tracking: Okay, So welcome, Teoh. Video number 19 all about polar tracking. So if you want to go and check out your drawings on open number 19 polar tracking Okay, then you can work along with me and we're gonna have a look at polar tracking. So the first introduction I want to give you is that polar tracking is a new feature within AutoCAD. When I say new, I don't mean a week ago, I mean 15 years ago And that's in the context of the fact that order card is now over 30 years old. Eso It's relatively new as a concept and ah, some people who were aware of auto cad previously, um, would realize that there was, ah, function called also mode which allowed you to control left, right and up and down on whether you were snapping toe horizontal or vertical. But the new version is called polar tracking, and it's by far my favorite way of doing things. It automatically recognizes what you're trying to do in terms of left, right on, up and down, and you can also put some of your own settings in between. So it's really, really useful, very flexible on extremely easy to use. We're going, Teoh, have a look at the way in which order cared uses angles first. And it might feel a bit odd because if you think of a compass, a new started nor, uh, north is normally not on their four East is normally 90 degrees. But I'm unfortunately in cad. None of that matters. Okay, so we have to learn a new way of measuring degrees east. Is zero okay on the reason East zero is because the X axis always comes first. So the horizontal for the X axis from zero across is zero degrees. And therefore, if you rotate through 90 degrees to get north, not only you're going anti clockwise, but you come to north first and then 90 degrees further is west. That's 180 degrees. Still going anti. Clockwise on south is 270 degrees. So you might want to get a piece of paper and just write that stuff down just so that it confirms into your mind that east is zero North is 90. West is 180 south is 270. So once you've got that in your brain. You can understand my little exploration on the left hand side. So that's what we're going to be working with. And we're gonna be creating that on the right hand side in terms of the lines that we're going to be drawing. So first of all, we're gonna find out where polar tracking is on the interface and its down here on the bottom bar. On the right hand side, it looks like a clock on its got two hands on it and it looks like 10 past three. So if that's blue, it's on. And if it's grey like this, it's off. And, of course, if you turn it off, the command line also says polar off. So if I turn it back on polar on, polar off, polar on, polar off alone good. You can also use F 10 toe toggle lack back on and off so you can see I'm just pressing F 10 F 10 F 10 F 10 on. That's a great way of getting to polar tracking. No, you can accidentally use polar tracking and also mode together at the same time they are mutually exclusive. So if you have also turned on. You can't have polar tracking. And if you have polar tracking turned on, you can't have also on. What it means is that if you're in the middle of a drawing a new turn, also on it will turn off polar tracking. So be aware off that. And I would say just for a moment, if you're new to auto kid, don't try turning also on because turning also off doesn't immediately turn polar tracking back on. Okay, you can have a drawing where both the turned off. So be aware as to where polar tracking is and make sure it's turned on. Okay, it's turned on right now. So we're gonna draw a line from the center of the circle on the right east, and we're gonna make the length of that line one meter, 200. Okay, so we're gonna do l for line over here on the circumference, find the center of the circle and click. Then we're gonna come out horizontally, and you can see now the green line extends out. That's the polar tracking. I'm gonna type in one meter, 200 press enter and then enter to finish. Okay, so there's our line already in place. Okay, on. That was pretty straight forwards, wasn't it? So now we're gonna go for a line that's not so straight forwards. Okay, what about 36 degrees? Now, if we want polar tracking to control that for us, we're gonna have to turn it on inside the polar tracking settings. So we place Emmaus on top of the button that we found earlier, right? Click and choose the tracking settings here. So here we are. We're inside the drafting settings on. We're on the tab called Polar Tracking on. I want you to find this extra tick box. At the moment. It's on ticked A ticket, and we're gonna add our own additional 36 degrees. So we're gonna go here new 36 enter now we want to more settings as well. We want 138 degrees, and we want 245. So we're gonna go new 138 typing on the keyboard, and then we're also going to say 245. So new 245 enter. Okay, So once we've done all of that, we can click. OK, Let's see if those angles turn up. L for line. Start in the middle. There we go. Almost immediately. Jumped straight in on 36 degrees and we're gonna draw a line here on the length of airline is going to be one meter, 200 on end to finish. Let me die. Good. Let's try the 138. So we're going to start the line command again. L enter Start at the beginning off the center of the circle and come out here. It's pretty easy to find is not. Make sure you don't sit on other piece of geometry over here Whilst you're trying to type those commands in because you need Teoh, give alter cad the mouse position to know that you're picking up on the polar tracking. And it's only when you get that green line shooting out. You know that the polar tracking is active. Okay, so it's 138 degrees. We're gonna type a line of one meter 200. So that's 1 200 on the keyboard. Enter on, enter to finish. Okay. Which is gonna finish off with the last one now? 245. So that's going to be l enter. Click on Come down here. That we are. It jumps straight in. Okay, you could argue that this has a negative angle or a below horizontal angle of 115 which is also true, but in terms of our 360 degree compass angles Okay, we've got 245 as well. This line is also gonna be one meter 200 long, so just type the end at the keyboard. Want me to 200 on enter to finish. So it's pretty straightforward, isn't it? And ah, so you can rely on auto cad to guide you with polar tracking only if it's turned on. And only if you look for that green line that pops out to say that polar tracking is active . Okay, have a little place. If you can dream up some other angles on make some other settings on DA. Come and join us in the next video. When you're ready 23. Polar Tracking Off: So we've just done what happens when polar tracking has turned on on. Now we want to have a look at polar tracking off. So let's just check First of all that you've got your drawing open. So open your drawing number 20 polar tracking. And then we're gonna have a look in the bottom right hand corner of these buttons here, and you'll see that the polar tracking Batten down here That looks like a clock set to 10 past three. Okay, just make sure that's the gray version, not the blue version. Blue is on Grey's off, and as you turn it off, the command line should also report polar off. Okay, so we're going to start drawing some lines just like we did before using the line command l enter. We're gonna choose to start drawing from the center of this circle, so make sure you pass over the circumference and pick up the center on this time as you turn your mouse around 360 degrees, we're only getting the dynamic input. That showing you what's happening? We're not getting polar tracking snapping out. Okay, so I'm gonna bring my mouse over here, and you can see that it's not at all horizontal, But I can still draw a horizontal line because I'm going to say it's at zero degrees east zero. So I'm gonna type in 600. Is the length on tab to move myself across to the degrees on? I'm gonna type in zero. Enter and there we are entered to finish. I've now got a line. I can select it. That is 600 long and at an angle off zero. And you can check that up over here on the right hand side in your properties dialog box. Lentz 600. Okay, angle zero really escape to get out of that. So we're gonna draw another line north guy now enter. Click in the center, and then we do get a green line that pops up, which is nothing to do with polar tracking. Okay, this line is to do with oh, snaps on its understanding where we came from, that end point, and it makes an assumption. Do we want to draw north? And of course, the answer is no. So I'm going to ignore it. And in fact, I'm not even gonna try to get my line pointing North. Okay, But so long as I tell auto cad that it's gonna be drawn at 90 degrees, I can type in 600 tab 90. Enter, enter to finish. We go. Let's check that. That's true. Select the line. So it's got blue grips on. Have a look in your properties dialog box on. We should have lent 600 angle 90. So next we're going to try drawing an intermedia angle on. Of course, the 1st 1 we did earlier was 36 degrees. So we're gonna have a go at doing that. We're going to start with the line command, go back to the middle of our drawing and pull out approximately in the right direction and type in the length 600 tab. The angle, which in this case is 36 enter and to finish. There's our line with the right length on the right angle. Let's double check by selecting it. Have a look in Properties 600 at an angle of 36 degrees. Okay, so now we're getting good at this. Let's do the other one. Let's do the 138. Okay, line, enter. Click approximately the right position we're above the horizontal. That's why I'm saying, if we go down below the horizontal dynamic input could accept a clockwise, uh, angle. So we're not gonna do that so above the horizontal. And we're gonna type in 600 tab 138 enter and to finish. So there's a secondary intermediate angle again. We select it, check it in the properties 600 at an angle of 138. Okay, let's do that one that's underneath the horizontal now because dynamic input will switch around the direction of the angles. L enter click. And, as you can see as we come round and down, then all of a sudden, dynamic input is declaring 90 degrees is pointing south on. So if we want 115 degrees, we just put it approximately in the right place. Type in the length 600 tab and in our case, 115 enter and to finish on what you'll see when you select that is that it says the right lengths. Yes, but the angle is true to auto cad, as opposed to dynamic input. So there therefore it reports back 245 which is the same as 100 15 because 115 plus 2 45 is 360. So there we go. Escaped twice. Onda have a play with polar tracking turned off. See what other lines you could draw. See if you can predict where to place your mouse to make sure everything looks correct and is correct. Check it in the properties by selecting on looking at the details just to make sure that you're correct. All right, we'll have fun. Um, we'll see you in the next video. 24. Copy Command: So this next series of videos are all about The transform commands were in video number 21 called Copy on De. So if you'd like to open up your drawing that relates to this video on your drawing was also called 21. Copy. We're gonna learn how to copy some stuff around. Okay? And you can see I've already been playing with some of these rectangles. Onda, I'm gonna show you how I'm going to copy this rectangle from here straight up on polar axis 90. So I'm gonna issue the command. First of all, on the command in order card is C o P Y enter the command line says select objects. So I'm gonna put a blue window from the left hand side of the screen towards the right all over my rectangle. T pick it up. Once it selected, I press enter on the base point. Now is the next thing we need to choose. So if you look at the command line, it says specified based point, I'm going to choose the top left hand corner off my rectangle click. I moved directly north, and as I get up here, I'm gonna type in one meter, 200 enter. And because we were on polar axis, Okay, it's copied it up precisely the amount that we've asked. And if you want to just double check that we can use a measuring tool, which is up here, which is just this Rula. And I'm gonna measure from my base point to my second point, and it says one meter to hunt. Okay? And escaped. Come out of that now. I'm going to actually now do an undue on. The reason I'm going to do an undue is because copy will repeat more than once. So I'm gonna show you what I mean by that. I'm gonna use my ordinary control said to undo. Okay, so I'm gonna use the copy command, and in this case, I'm gonna use the short cart, which is C O C. O on the keyboard and presenter. Then copy the objects with a blue window. Anto, the base point is the top left hand corner click move straight up on polar 90 degrees and we're gonna type in the length, which is one meter 200. And there we are. We've got our copy, but we're still going. So let's do one over here on the left hand side. Make sure your snapped to 180 degrees will type in the distance on meter 800 enter. And that we are. We're still going. So we're gonna try something up here at a distance of two meters at a angle off 135 degrees . So that's gonna be 2000 tab. 135 degrees. Enter and end to finish. So you can see now that first of all, copying is straightforward. All you gotta do is select the object and decide on the direction and the distance. And, of course, you've also got the fact that it repeats itself. It continues copying until you say I've finished, which is presenter. And so we've copied up. We've copied sideways, and we've copied at an angle. Okay, so that's great. Now, down here on the right hand side, you'll see that we've got a copy, okay? And, ah, we can copy randomly. Let's have a little go at copying randomly. So we get a feel for what's going on. So here we are. We're going to say C O, which is a short cut for copy. Select this small circle. We're gonna pick it up in the middle, and we can put it down wherever we like. Okay? And as many times as we like, so you can be as random as you like. And as you notice, if you've got polar tracking turned on, you can snap onto polar tracking a swell, great and enter now in the bottom right hand corner. We can show that we can do a linear array with the copy command. I'm just gonna talk you through that, Okay? This little heading to gives you a bit of an idea as to what we're gonna do. We're going to do the copy array. We're gonna do four in the copy, we can counter circles. 1234 at 600 millimeters apart. So we're gonna type in copy and select this circle on its own and press enter. We're gonna pick up the center as a start point and pull in that direction. But if you look at the command line now, you'll see on the command line. One of the options is array. So we'll just use the capitalized letter for that. A enter How many items in the array. Four. Enter what's the distance in between 600 and toe and enter to finish? Good, so that's pretty cool as well. So have a little play with those ideas and practice them until you're good and then come and join us on the next video, which is all about moving objects around. 25. Move Command: Well, we're already on video number 22 which is all about moving. And so if you want to open your drawing number 20 to move and you can work alongside May. Okay, so the move command is very straightforward, Very much like the copy command. But you're going to get one go at moving your selected objects. So here we are. We're gonna move the desk on the chair in the middle, okay? And we're going to issue the move command, So that's M O V E on the keyboard. Enter. We're going to select the objects, and I'm using a green crossing window to select them. You can use any message you like to select. You can click on things you can use a blue window around the chair, for instance. It's really easy to do a green crossing window here. Press enter wants the objects are selected. I'm going to use the center of the chair as my base point. I'm gonna move directly north, and in moving directly north, I'm gonna type in the distance, which is gonna be 900 enter. Okay. So because I was snapped onto my polar access, I only had to type in the distance. I want to move. But if you want to move it an angle, we can do that too. Let's do this one on the left hand side. I'm going to use the shortcut for my move. Command, which is m enter. Select my objects and press enter on, then pick up the center of my chair and then move over in the direction I want to move, and I'm going to say that I'm gonna move a distance of 400 Tab 1 25 So the angle was 125 degrees. It's proof. Practice that on the other side I m enter, select and, uh, click on them type in the distance. 400 tab 55. Enter. Pretty straightforward is now on. If you do that a number of times, you'll get a feeling of the flow of the command. You know, it has a rhythm of its own, and ah, so give it a go. Maybe do a couple of undoes on, then repeat the exercise from the original off from the start. Okay? Because when you're in order card, you're gonna be doing a lot of moving. And if you're really confident at it, then, that you're going to speed up the whole of your operations elsewhere as well. Okay, Good. Right. See you in the next video. 26. Rotate Command: So this is all about the rotate command. So open up your drawing number 23 rotate. If you want to work alongside now we're gonna try the desk and the chair in the middle. First of all, you'll see it top it says rotate 180 degrees. Andi in red in the middle, It says Use the geo center off the chair as the base point. So we're gonna issue the command first of all, so that rotate r o T A t e. You know, we'll type at the keyboard r o T a T e enter. We're going to select the objects. I'm going to choose a green crossing window cause it's really fast in tow. Used the geo center of the chair and click. And as you start to move, you'll find as you get to each of the polar tracking points, which is north, south, east and west. It snaps into position. Okay, so you can feel it. Get to 180 degrees and snap. So just make sure your mouse is on the green line. Click and you've achieved your first rotation. Well done. Now, of course, if it doesn't snap, Then you're gonna have to type in the degrees. So let's use the one on the left hand side and you'll see that we're going for minus 45 degrees. The short cut for rotated are Oh, so let's type that in at the keyboard. Aro, enter. Select the objects and, uh, click start to rotate minus 45. Enter. Great. Fantastic. Now, of course, minus 45 goes clockwise. So if you want to go anti clockwise, you use positive degrees, and over here, we're gonna try that. So over here, we're going to do the right Take command on the right hand side. So that's our enter. Select and, uh, click start to move 36 degrees. Enter. I'm a guy. So we've done a rotate 180 degrees. A rotate clockwise minus 45 degrees. Onda rotate anti clockwise. 36 degrees. Okay. So well done for completing your first set of rotates. And ah, if I were you, I'd just take a little time to repeat the exercise just so you get in the swing of it. Remember the rhythm of the command so it's rotate. Enter, select. Enter Base point Number of degrees. Okay, so it's got a rhythm to it. And ah, what you'll also remember is that positive degrees or anti clockwise and negative degrees are clockwise. So have a play and join us in the next video. 27. Scale: So this is video number 24. All about scaling eso. Let's open up the drawing to go with this video number 24 scale. Good. So we've got three different types of scaling here on the left hand side. We've got a scale up to a new size in the middle. We've got a scaled down to a new size Onda on the right hand side. We've got a scale relative to an existing object. Okay, so let's start with the left hand side. You'll see that we've got a base point annotated here, So we're going to use these based points that we've got chosen and I'm gonna type in the scale Command first fall. Okay, a scale S c a l e ente. I'm going to select the white box and press enter. I'm going to choose the base point here on the bottom left hand corner. And as I move my mouse, the scale goes a bit crazy. So I'm just gonna type in three enter, which basically means three times the size. Okay, that's pretty easy. Sensible way of organizing your scale command. So now that we've got scale up, let's do a scale down Okay, You can see from the example of the bottom. We're gonna go from a big box to a small box and we're gonna issue the scale Command first . The shortcut for scale is SC. Enter select the box Ente, click on the base point and then type in the scale factor, which you can see Here is 0.330 point 33 enter. And there we are. We've got a box which is now 1/3 of the original size. So that's not too bad. Now let's have a look at the third exercise on the right hand side. This is a bit more complicated. So if I were, you jump up and down, shake yourself a little bit and concentrate on this one. We're gonna issue the scale command, and we're going to select the smaller white box and time. We're going to specify the base point in the bottom left hand corner. But then look at the command line at the bottom and it says you have the opportunity to use reference as an option. Okay, we're going to choose that. So are enter. Our reference length is the short bottom edge of the white box. So we're gonna click left to right, Left hand side first, right hand side. That's a reference length on. Then, as we increase with the mouse, you can see the white boxes getting bigger relative to the red box. We get to the end point of the new box and click. Okay, so the now the white box is exactly the same size as the red box. Let me do that again. I'm going to do a control, Zed to come back and just talk you through that one again, cause it's bit more complicated, isn't it? So SC is the short cut for scale. Select the white box Empress. Enter. Click on the base point. Choose the reference option, which is our enter Andi. Choose the reference length from left to right. So we're going from the base point to the end of the reference length. And then as you move your mouse away, click for the end point here. Good. Okay. Now, that will need some practice, and you'll just need to have the confidence that the command line will lead you through it . So have another play with the scale command and, uh, see if you can get confident at that. Once you are join me in the next video on. I'll see you there. 28. Mirror Command: Okay. This is a video all about using the marital. So video number 25 mirror. Let's open the drawing to go along with this video, which is drawing number 25 mirror. So let me talk you through what we're going to do. We've got some desks and chairs here which we're going to mirror, and we've shown the mirror line with a red line. You can put a construction line into your drawing if you want. Um, it's there just for convenience. When you get used to AutoCAD, you may not need a construction line, but we have a construction line just for our convenience here, okay? And we're going to mirror the one on the left hand side, first of all, and we're gonna mirror from left to right, So we've got to issue the mirror command M I double r o r. Enter. I'm going to select the two objects and press enter. My first base point is on the X, and I'm gonna come up to the top of the line, find the end point and click on it on reply. It raised source objects. No. Okay, so that's your first mirror, and you can see, we've flipped the desk and made a copy at the same time. Good. So let's go to the center. Example. This one. We're going to just flip down using the horizontal mirror line. It's exactly the same process. It's just repeating in a different way. Tonight. We're going to use the short cut for mirror, which is M I. Enter Emily Sameera. Select the objects and press enter. Pick up the base point click. I'm go to the end and click No, to erase the sore subjects on this one. Good. That's pretty straightforward is now so we can do vertical and horizontal. How about if we do one at an angle? Good. It's exactly the same. Same rhythm, same everything. Okay, let's just try the short Cut em. I enter select and, uh, base point click en pointe. Click. No. Okay. Pretty straight forwards. So since it's got a nice little rhythm to it, and it's always gonna be that rhythm if you stick with command first and then select and ah , just have another go reset the during. Try the tutorial again on get really good at using the mirror command 29. Command Rhythm: Hi. Welcome back into our next video, which is video number 26. And it's all about the rhythm of the commands and the card line. So one of the nice things about Water Cat is that it follows the same rhythm every time for each command. It has its own little rhythm. Andi, you'll get to learn that the more you practice it and a lot of it is Connecticut memory because the more you do it, the more your body and your muscles remember how you did. It's bit like riding a bicycle. Okay, so if you wanna open up your drawing command 26 on have a look at what we've written here, or just watch this on screen because this one, you don't actually have to do anything necessarily. Um, but I'm going to show you how the commands have got a bit of a rhythm going to it. So if we look at the move command first. Okay, The move Command just requires you toe enter the command at the keyboard or by choosing one of the buttons up here. You see, you got move. Copy, stretch, rotate mirror scale up here. But to be honest if you go and take your eyes off the screen and look for buttons rather than just typing in M. Enter, a mentor for move is so quick that you don't even have to think about looking for button. Plus, of course, it's all part of your kinetic memory. And if you keep it within your commit kinetic memory, then of course it's, Ah, whole Siris of movements that you do with your hands rather than moving your eyes on. Then finding a button to click on on a button to click on with the mouse doesn't develop kinetic memory in the same way. So I'm gonna press escape twice. I'm going to start the move command again. Here we go. M enter the command line says Select objects. So that's easy. Then the command line says, Are you still selecting objects? So in order to finish selecting objects, you must press enter and then the command line says specified base point. So that's the first point of displacement, and then that's the second point of displacement. But if we analyze the command, what you'll notice is that we have what we've got written up here, okay, which is move. Enter select objects. Enter base point click. Second point click. Okay, so that's an easy rhythm to remember is now. So command, enter select. Enter base point click. Second point click. So I'm just gonna go through the move command again in that way. So m enter. Select and, uh, based point click. Second point click. Okay. It's got a rhythm to it has now. Okay, let's try that again with the copy command. Joey. Great. So it's copy. Enter, select. Enter based point click. Second point. Click. Next point. Click. Because you can keep clicking as often as you like with copy. Okay, so copy, Enter select Enter based point click. Second point click. Next point, click. Next point. Click. No fuego. Good. So if you've got the drawing open and you want to practice that, give it a little go. Because once you realize there's a rhythm to it, then you might feel a little bit more comfortable about the commands and carrying them out . Okay, Good. Give it a go on. We'll see in the next video. 30. Dynamic Input: So here we are in video number 27 all about dynamic input. Dynamic input is something that happens in the background almost invisibly. And you probably won't realise that you've bean watching the results of dynamic input. And this is also true for objects Snap tracking on polar tracking. It makes our drawing life a lot easier. And it's very simple and straight forwards on This is the method that we've been using without realizing it for drawing the lines. This is what we've already practiced on. I'm just gonna point out precisely the way in which it works with the line command. We're going to use the line command. The short cut is l enter. Start in the center of the drawing at this small red circle on click. And then as we come out horizontally, we're going to type in 600. Enter and enter to finish. There we are. We've got a 600 millimeter line that's easy to put in very quick. Okay. It's horizontal on. We can rely on it. Let's do another one. Let's do one to the left. Okay. And also, if you're aware of the compass settings on old head at an angle of 180 degrees. So we're going to repeat the line command, which is enter. Click into the middle of the red circle. Come over here. Keep on polar tracking 600 anto and enter to finish. Now that's really, really simple. Now let's have a look at the way in which the dynamic input is interacting with us at the time. Let's try and draw a line going directly north. Okay, l ente click into the middle off the circle, and as we go north, you'll see on the left hand side in blue. We've got the length of the line. That's the dynamic input on. On the right hand side, it says it's 90 degrees, which is also part of dynamic input. The Green Line is part of the polar tracking and the snap tracking and so all good. So everything's fine and it works really easy. So let's type in 600 enter and enter to finish. Now, we've been supported in our drawing by these three extra features, but what happens if we turn them off? Okay, so I'm going to use control, said to go back three steps and then I'm gonna come down to the right hand side of my interface, and I'm gonna to find out those items which we're going to turn off here. Festival. We've got polar tracking. We can click on that on when it's great. It's turned off here. We've got object snap tracking, and we're gonna turn that off on. I've got my dynamic input baton turned on. You may not have your dynamic input button turned on as it's not turned on by default. Okay? And so if we go right to the end of this panel right in the bottom, right hand corner, click on the customization tab and you may want to turn it on up here. Okay? So if you find dynamic input appear, if it's not ticked, click on dynamic input to ticket the button should then appear here. And of course, you can turn it off. So with all of that turned off, we're going to try the line command again, and we're going to draw a line from the center of the circle over to the left, which is west on. We're going to use this format here on the keyboard. We're gonna type in for the second point shift at 600 at an angle off 180 degrees. Okay, so we're gonna start the line command in the north of the ordinary way l enter. We're gonna pick up the center of the circle in the ordinary way and click. But this time you'll notice that because there's nothing to support us, then we've got no polar tracking, no dynamic input, etcetera on. We need to tell water can what precisely were going to be doing. So we'd hold down the shift button and at 600 at an angle off 180 enter and enter to finish . So you'll notice that the keyboard entry for angle is the brackets that look like on arrow beside the M just above the space bar. It's not the arrow buttons that we use for navigating in VR. It's the arrow bracket that certain just near to the question mark in the M on the keyboard . Okay? And don't rush the shift. Okay? Don't hang about on the shift too long, either. Otherwise, you might activate a Windows command, but shift and then at Okay, 600 at an angle off 180. So let's try at 90 degrees. Okay? We're gonna try the same command l enter Start in the middle of the red circle and we're gonna type in shift at 600 at an angle off 90 and, uh, enter to finish. Okay? And then we're gonna try this one over here, which is the 45 degrees. It's the same procedure l ente click for the first point of the start point, and then we're gonna type in shift at 600 at an angle off 45 and, uh okay, so it's not too frightening, is it? Move and copy work in exactly the same way. So we're going to copy this desk and chair. So we're gonna type in CEO, enter select with desk and chair ente, click for a base point, and then we're gonna type in shift at one meter, 200 at an angle off 45 degrees, enter and enter to finish. No, I'm gonna make a recommendation here. My recommendation is that you keep dynamic input on you. Keep polar tracking on and you keep objects. Snap tracking on. Okay, 99.9% of all of the time. Maybe 100%. But you might argue that there is a reason for turning off those those assistance, and the reason it might be is that you want to actually draw to riel coordinates as opposed to relative coordinates. So the way in which dynamic input and put a tracking helps you is that you don't have to know the coordinates of the drawing that you're in for you to make your lines or your copies, because all of the movement and positioning is relative to the first point that you click. However, if we were to draw a line, let's just say over here and you decided that the line wanted toe end up at the X y Zed Center. The origin off your ex wife, said coordinates that origin has a corner off zero comma, zero comma zero. So when the command line says specifies the next point, with all of this turned off, you could respond as if you were entering a coordinator. And so I'll try that zero comma zero comma zero enter and you'll see that the line goes to the origin. So there we have it. Two different ways of working on the most simple way of working is to leave. The defaults turned on with dynamic input turned on objects nap, tracking, turn on and polar tracking turned on. If you get to a point where you become a super expert, obviously you might like to know Maura about that. And it's worse practicing eso maybe undo your changes here and, uh, reload the drawing and go through this little, uh, tutorial once again and see if you can master all of these black arts okay on, then we'll see in the next video. 31. Properties: Okay. Welcome to video number 28 Properties. This is a whole new aspect off. What a cat on de. So I suggest we get the drawing started and opened, and we'll have a look at properties. If you open up your drawing number 28 properties, you can work along with me. Here we go, then. Every object in order card has a property on DA. I've got my properties dialog box open outside on the right hand side. Now, I consider this to be a really good idea to have the properties dialog box open. Okay, Pretty much all of the time on. So I leave it up here on the right hand side. Now, if I closed my properties dialog box down, okay? This is probably the arrangement that you've got on screen. At the moment on. I'm gonna show you how to get your properties dialog box in place. Okay, I'm gonna select any one of the objects from screen, then right click. And at the bottom of this menu is an item called properties. Click and you get the properties dialog box open. Now it's possible that you might have it open somewhere over here. where it's just floating around. But if you grab it at the side, see, there's a bar going down the side here called Properties. If you grab it a side drag all the way across the right hand side on. When it starts to disappear like this, drop it and it will park itself on the right hand side of your drawing on. This is a brilliant asset to auto cad. Now I want to explain what's going on here because the properties dialog box displays the properties of your drawing or the properties off the selected object. Okay, now this is brilliant because it means that you can inspect a selected object. For instance, here's this line and I'm going to select it. And in the Properties dollar box, it tells me it's a line and then gives me all of the details that belong to that line. Okay, so if I do an escape, I can then select, for instance, a circle. And there we are. We've got a circle on in the Properties dialog box. It says it's a circle and one of the items down the bottom. Here under geometry, it says Radius 450 diameter, 900 circumference and that sort of thing. So that's fantastic. And we get lots of feedback. I'm just pressed escape to come out of that and to de select my circle. Right. So the Properties Dialog box will also show us the properties of the drawing if we have nothing selected. So just make sure that you've pressed, escaped twice, and there's no grips on the drawing. What we see here at the top under properties is no selection, which is great. And that means anything it shows. Here are the properties off the overall drawing. Okay, which means, in general, that the settings are completely standard here at the side. Now, this may not mean a nor ful amount to you right now, but I'll give you an example. At the moment we are drawing on layer zero, and this tells us here that our current layer is lair zero. And if we check in the properties also, it says that the current layer is layer zero. But if we wanted to, we could actually open up this look down the list and switch over to a different layer. Okay, so now the current layer as you can see now up here is dimensions. So you've got control over your drawing through the properties dialog box. Now, this brings us to another subject, okay? Because this teaches us the auto cad isn't just a brilliant drawing package. It is also a database. The engine that drives auto cad behind all of the lovely Goering's that we see is a solid database on If we have the properties dialog box open, we can actually get access to that database. And we can change stuff about the database. And I'm going to give you a really good example. We have a circle right in the middle of our drawing, and if I select it, you go to the properties Donald box and you'll see it says it's a circle. Brilliant. The geometry says it has a radius of 450. So if I highlight that and I changed it to 250 the circle in the drawing changes. Okay, so this is really amazing stuff. It means that if we've done something and we've changed our mind, sometimes we can actually go to properties and fix what we've changed. Instead of having to redraw it. Let me give you another example. I'm gonna press escape twice, and I'm gonna highlight the text here. Onda. It says here the text is 200 millimeters high. And if I go into my properties Donald box, it says text the contents. It says text 200 millimeters high. Okay. And down here on the height, it says 200. Now I'm gonna change not only the contents, but also the height. So I'm gonna type in new text and presenter, and you can see it changes in the drawing. And I could go to the height and Aiken type in 300 presenter on again. It changes in the drawing. So that's fantastic, because it means that again, we have mawr control. We don't necessarily have to delete stuff just because it's different to the way in which we imagine. Okay, now, if I press escape and I select this chair here, we'll find something else very interesting. Properties block reference. Okay, but under miscellaneous, we can see the actual name of the block. Well, I understand the details a bit more about it. Okay. Now, as far as we're concerned here, we can go on through all of the objects within our scene, just picking them up on finding out information, which is a good thing. But we can also manipulate things that we've drawn a little earlier. Let's have a look. This series of lines that we've got at the bottom. We have a yellow dotted line, and if we select it, the database tells it like this. It's a line. The color is by layer, and that color happens to be yellow and the layer is hidden, so it doesn't mean we've hidden the layer. It means it's called Hidden. That's the name of the layer. And if we open up this list just like we discovered a minute ago, we could put this onto a different layer. So if we go to dimensions you can see in preview, it's gonna turn red. If we get a furniture, it's gonna go like blue, and if we go to zero, it's gonna go white. So that's brilliant, isn't it? Because that means that we can actually change their minds about which layer we have drawn on. Okay, so we can switch that one over to the dimensions layer, press escape and select the one that was on dimensions and put that over onto hidden. So we just swapped the whole to over having me and just changed our minds completely. Okay? The other thing they will see is the third line down from the top. If we select it, it's not a line. It's a poly line, okay, so subtly different. It reports back exactly what's going on and down here. We've got all sorts of information about it, and we can find the global wits of that Polly line at the moment is nine again. We can change your mind. Let's say it's 18 in tow and you can see that the line has got thicker. So it's fantastic, isn't we've got lots of control just because we've got this Properties dialog box at the side. Let's even go to the word that we've got the title for our drawing program here. Properties will select it on down here, it says. Text in the contents. It says properties, and then the height. It says 200 so we could change something about that. How about changing the rotation that's changed the rotation Tu minus 90 and you can see that the properties text has changed on screen. Onda, we might say, Well, hang on a second. That's a bit mad. I don't want it to be like that. Let's have it at plus 90. Okay, great. Even more bizarre, but still, at least you can do it. That's the point. Okay, and I could reset that back 20 So it means that once you've discovered the properties dialog box, there's a whole bunch of things that you can do. Let's move this box here that we drew on. Let's move that from Layer zero to lay hidden. So changing layers is one thing, but we can also change the global wits off this rectangle because it's a poly line and we can put in 12 for instance, is a global wit so that you can see also, we can change our mind about the sickness of the line if we want to. We press escape twice, perhaps on this rectangle we would change that over onto layer dimensions and escape, and we could change this circle over onto layer furniture and escape so you can see that there is a huge amount that you can do just to change the way in which you see or perceive your objects within auto curd and being able to change your mind at once you've actually drawn something is fantastic and saves you having to delete and redraw. So the properties dialog box. Once you've mastered it and you know where to find it, keep it at the side. Keep it there all the time, and that means that was speed up. Your overall drawing experience make you more efficient and perhaps also because you've got the properties of the side. There you can inspect the properties and see if there's something that you would like to tweak because it shows you the potential as well as the things that you know about. 32. Quick Properties: Onda Finally, uh, AutoCAD also provides you with quick properties, as you can see from the title of this video. Uh, so if we select on object, we can right click and we can choose quick Properties and you could see that we get this little dialog box pop up with just minimal information about the object that we've got selected. So it tells us that it's a line. It tells us that it's using the by layer color Onda. It's on layer dimensions Onda. Just this little item here about the line type and the length. Now this changes with every object that you pick. So, for instance, it would give you a different type of quick properties for Upali line. Okay, here we go. So color layer lying type global wits on whether it's closed or not. So just the most important part off the bits of information that we want to know about Polly Line. But to be honest, all of this is available in your main properties dialog box. So if you're using quick properties, then that's fine. That's a very simple thing. You can only get you quick properties if you've selected something. For instance, this circle and then right click, and it's at the bottom of this menu. But the contents off Quick Properties is no different to your properties over here on the main properties. Don't Box, of course, has got more detail rather than the small amount of detail it's available in quick properties. So the choice obviously, is up to you as to which one you want to use. And, uh, it says Quick properties. And, of course what it means. Is it short list? Because if you have the main properties Donald Box open, of course, that's quicker than actually opening a dialogue box every time. So my preference is to stick with the big Properties dialog box permanently, uh, positioned at the side of the during choice is up to you, but both of those options are available. Okay, so maybe you'll need to go back to the beginning. And just to go through this video once more so that you're completely familiar with the Properties dialog box, how to get hold of it and what it contains Ah months, you are. We'll see you in the next video 33. Layers: So here we are in video number 30 layers. Andi, if you'd like to get your drawing number 30 open as well. Not be great on. Then we can work along together. So if you don't know what layers are, it's a way of digitally organizing your drawing on. So we're going to discuss the concept of layers and how they work. Andi, uh, I'm going to show you a little part off the interface, which you're probably notice up here. We have a pull down menu on this pull down menu allows you to control existing layers. Okay, What you're allowed to do is you're allowed to turn things on and off, so you can see that just by clicking on to some of these buttons we can hide all reveal layers. So that's the big thing. Really? So let's have a look at joinery. Okay? You can see that little blue line turns off there or look further up center line. We could decide to hide the center line. We'll reveal it on DA. Everything on centerline is green. And as we turn off this, you can see and identify the centerline more easily. Can you? So first and foremost, it helps with visual recognition. So if you're on screen and you know that your center lines a green, then you can pick them out a little bit more easily. But also it's a way of revealing mawr information. So, for instance, as you zoom into a drawing, if you're gonna print it out at a very small scale, then you might want to have only a little bit of information turned on. But as you zoom into detail, for instance, you might want to reveal mawr information so that you can print out. And if you zoom in even further, you want to turn on even mawr information that you can reveal as you zoom in. Great. So this is a way of controlling the amount of data in your drawing at printing on plotting time. Of course, the whole point of doing on auto cad roaring is to communicate to somebody else your ideas , and therefore it has to be effective communication on the printing and plotting, even if its only to save our pdf will be a fantastic way of just bringing your information , your ideas to somebody else or another group of people. So layers allows you to organize your drawing both in color Andi in the way in which the lines are displayed. So, for instance, on the center line we've got a long dash in a short dash on on the hidden layer, the yellow hidden layer. We've gotta Siris of short dashes, but all of the other lines are continuous. So all of this information is associate ID with each object. For instance, a line, and you'll see that if I select one of these lines here at the bottom in the properties dialog box that we've got at the side, it says that the color is associate ID by layer. In other words, it's controlled by the layer command. And if we were to say for layer zero, what's the color escape? We can go into the layer dialog box. I'm we can find out. So let's go into the next video aunt. Have a look at the layers dialog box 34. Layer Dialogue Box: getting into the lead Dialogue boxes easy. We just type in the command layer l a y e r presente And here's the layer dialog box. Let's have a look at the layer zero. And there we are. It's color is white. Now I know you could have predicted that about the important thing is it's controlled by the layer dialog box. Okay? And if we were to change our minds, we could click onto the word white, Choose a completely random color. Okay? And now you can see that all of the objects drawn on layer zero are now this magenta color . I'm gonna put that back to white. That's a bit random is now. So there we go. We're back on the lam onto layer zero, and the color white now, color white is also color. Number seven on this is the only color that has some special properties. So this color will be white on a dark background and black on a white background. Okay, let's have a look inside the color dialog box again. Okay, so I'm just left clicking onto the word white. Here's the color dialog box on number seven. Yeah, number seven is white, and it says white down here. But you'll also notice that down here we have color number 255 which also appears to be white. But it doesn't call itself why it only calls itself 255. So what's the difference? Color number seven automatically changes depending on the color of the background. But color number 255 does not. Okay, The same is true for this color. Here it looks black. Okay, it's color number 250. But this color doesn't change either. Only color number seven changes dependent upon the color of your background. So that's good. Because if on a black background your main outline appears to be in white, when you switch over to printing, then the main outline appears to be black. Now, there's also another reason for being careful about choosing your color. And I'm going to show you what that the reason is going to be. I'm gonna close down my color box and I'm gonna close down my layers Dialog box on in the main pull down menu from the top left hand corner. I'm going to open up print. I'm gonna hover here on print on then on page set up. This is your page set up, Manager. I'm gonna come across on in the page, set up manager. We can have lots of different page set ups. But the most important thing is I want to modify my page set up. I could do that with the modify button here on the right. And I get this panel on This is Ah, this is a dialog box which you're going to get used to in the end, because you'll see this every time you go for printing and plotting. What I want to show you is this pull down list in the top right hand corner notice. It's called plot star table pen assignments. OK, it's the pen assignments that I want you to log into your subconscious. Okay, on. If we open up this list, there's a whole bunch of presets for organizing your pen assignments. When you print on your notice, that gold got different names, but they end up with a dot C TV on the DOT CTB tells us it's a color table there. In other words, the pen assignments are dependent upon the color that you choose in your layer dollar box? No, that's very interesting, isn't it? Now there are two different ways of setting up you're drawing. It's using either the C T B way of doing it or STB. STB is a completely separate style table that uses names to describe the styles on is set up in a different way. And in fact, what you have to do is you have to choose right at the very beginning of your drawing exercise which template you're going to be opening up on. One set of templates have STB files on the other set of templates have CTB files and in fact, you may not have seen this before, So I'm gonna cancel this out, and I'm gonna close down my page Set up manager on this tab here on the top, left hand corner is called Start on. You'll probably recognize this from when you started. It says, Start drawing here, and we've got a little pull down menu here to show you what templates are available. But have a look. The first temporary I've got the top of my list, says named plot styles. And if I go down a little bit further. This one says color dependent plot styles. I come down to the one that I normally use. This also says normal international metric drawing template uses color dependent plot styles. And if we look down a little bit further to maybe one of the tutorials, this doesn't say, But I can tell you it's an STB, which is named plot styles as opposed to CTB. So you can see from this page that's called Start that you have to choose at the start of your drawing exercise which template you're going to be using. So let's get back to our layers. Our layer dialog box will allow you to choose the colors that you associate with your pen assignments. I'm gonna show you how it works. If we type in l a toe, open up the lead Darlow box and then, for instance, we're going to choose center line here, and at the moment it's green. But I'm gonna change that. We're going to change that for a good, logical reason. Okay, Now we are liberty to program any color to do anything at print time. Okay, now, that's pretty daunting, because not only do we have 255 colors here. But we also have the ability to choose true color in this panel and also colors from color books or round tables. Onda. That's amazing. So you're Pantone's and Raoul colors also things. But let's sir, just concentrate on the true color for a second true color. How many choices of you got? Well, you got RGB, And in each channel you've got 255 different choices. So with each channel red, green and blue, that means 255 times 255 times 255 which is 16.7 million different choices. Now you don't want to go. You don't want to have to go and program, you know, 16 million different colors just for plotting out purposes. Onda. That's not the whole point. So be careful not to go a bit random on that. Okay, but back in the index color, you can see the first tab here Index color. We have a number of colors that have been put aside on the 1st 7 In fact, the 1st 9 up here, including these two grays. But the 1st 7 are the most important because what Europe liberty to do is to say that the 1st 7 will print out black as opposed to the colors that they appear on screen. Now, if you think about a traditional drawing, most of the outlines and the details are drawn in black, and it's only occasional that you get some colors popping in tow highlights special things . So here's the way in which it's intended to work. If you only have to program seven colors, you can make the 1st 7 black, and then you can associate a different pen thickness with each color. And, of course, traditionally because this goes 1234567 you could start with your thinnest on red and your thickest pen on white on progress evenly in between. Okay, so color number one could be potentially a 0.1 millimetre pen Color number two could be a 20.2 millimeter pen. Okay, you see where we're going with this point 34 green 340.4 for science 0.5, the blue 0.6 from a gente 1.7 for white. So this fills the normal criteria for using pens on a drawing board or in one of your beautiful drawings that you're going to be doing now that your expert at auto cad And if you use this protocol, what also happens is that after a little while, you get used to seeing colors on screen, and therefore you can interpret what those colors might mean. So if you see a green pen, you know that it's gonna be printed out at about 0.3 of a millimeter. Or though there are thereabouts, depending on what you set up on dumb. If you happen to see a red color, you'll know it's one of the sinister ones. Now I want my center lines to be a thin line, so I'm going to choose in index color number one, which is different to this red up here, which is index color number 10. Okay, 10. Obviously, you can program that in exactly the same way as you can. Program number one, but again, traditionally, index color number 10 will just print the color that you've chosen. So if you wanted something to be read, you would choose color number 10 as opposed to color number one on a random. If you wanted something to pink toe print out green. You choose one of these colors. Yeah, so you can see that the rain goes got a fantastic Siris of color choices. So that's brilliant in itself, and they're very straightforward to choose. But if you are going to stick with this idea of a black ink at print time, choose one of these colors on, then program it later in the CTB file that will have a look at it in another video. So I'm gonna choose index color number one for my center line and say, OK, knowing that the center line is a sin pen and when I come up to the top here, you can see that my centerline has now changed color to red. Okay, so the layer dialog box is able to control all of the elements within your drawing so long as those elements are set to behave by layer. Now you can override that in the properties. But I'm going to suggest to you that you don't want to do that because if you leave everything by layer, then you can control them here. So the whole off the center line layer he's going to be read, okay. And therefore you can rely on that. My dimensions also, for instance, I would want to choose Red, cause that's a nice thin line. Onda my furniture. I might switch over onto a green layer because that's just a little bit sinner than the scion layer, and therefore I could get more detail into that. It's also true for my joinery. This might be too sick for my joinery, and I might use yellow, for instance, because I want some detail in that. Andi, if I have a look at my lighting, maybe I don't want my lighting on magenta. Maybe I want by lighting to print out a color on that wanted to be very obvious, so I would go and choose color number 10. Okay, and you can see it says color Top number 10. Here. Even though it is red, it's gonna print out red on the printer because I haven't chosen color number one right? Sounds a bit random, doesn't it? Now, if I look at my hidden layer now, you can see that 50 and yellow are the same color, and just to allow myself some latitude on screen, I want to choose a color that is obviously not the same on screen is yellow. So I could choose, for instance, on orange. Or I could choose, do anything. I like to be honest. And I could choose this color here, and therefore, it doesn't collide with anything else that I might have on screen. Okay, so once you're happy with those ideas, we're gonna have a little look at adding our own new layer. 35. Making New Layers: So we're using the same drawing that we used a minute Go, which is drawing number 30 layers on. We're going toe open up our layers Dialog box. Now we're going to use the short cut key, which is l. A enter and we're going to get the layers dialog box open. Now you can open the layers dialog box with this button here as well on the top Ah, section of our ribbon that says layer properties. That's not a problem, so you can use either method. But of course, once you know how easy is to use the l A short cut, then it's easy to get hold of your layers at any time you like. Now we've already got some existing layers already made in this example. If you were to open a completely blank drawing, the only layer you would have is layer zero. But we've added some extra layers here and that we're just gonna find out now how to make our own layers across the top of the layer list. Here, we've got four buttons. So have a look for these four buttons and the 1st 1 if you hover over that, it says new layer case of this little tool. Tips are always helpful. Click on this button. Here. I'm we're gonna add a brand new lad in Now this layer is gonna be called outline. That's O U T l I N e. Make sure you get the spelling right. A news. A capitalized letter to start with. Now there's no rules as to how you should type this in. You could use all capitals. You could use all lower case and the course. You can choose your own spelling or invent your own language, but that's not really going to help anybody. What would be a good idea is if you use the conventions dollar in place. So capitalize your first letter and the rest is lower case. We'll know about passwords that way. And, of course, if we use the wrong spelling in a password, we get rejected Now in Auto cad, we're often merging different drawings from different places that we could use a drawing from one plant on. Mix it in with a supplier from another place on. We'll have other people's spelling incorporated into our drawing because layers brought across when you bring in another drawing and Of course, you could end up with not 10 of your own layers, but you could end up with 100 of other people's layers on. If we all use random spellings. Then, of course, we're gonna have some duplications, which are unnecessary. A really good example of that is, of course, centerline. There's so many different ways of spelling centerline that we could all get into a real pickle over how maney center lines we have. There's the English and the American sell it spelling off center, which is E R R E. And of course, you could decide centerline is one word or centerline is two words. Andi. You could also decide to have sense line just a in the drawing mode, which is CEO. So if you have a look out engineering drawings, sometimes the center line is indicated with the letters C L. Um, so there's lots of different ways of spelling, and we don't want to get too fussy about this. But it's a good idea to sort out your spelling before you start adding in your new layers. Okay, so here for outline, we're going to go for a color of magenta because it's a nice, heavy, sick pen on. Then we're going to add another new layer in. Okay, This one's going to be called boundary B O u and D a r Y boundary. The color is gonna be quite dominant. So we're going to use a blue. Uh, that gives us a nice chunky pen, but we're gonna change it from our continuous line type. So if you left click onto the word continuous Okay, down in this new box that appears we can load in a new line time. So this button here called Load we'll click on that on, then. Have a look down this list of all the different line types that you can load in if and we've got this fence line here, so we're gonna use this is our boundary. So fence line circle. Okay. And then before we leave this dollar box, we must choose the fence line, toe adit or associate it with our layer click. Ok, so now we can see that boundary has the line type fence, line one. Let's add another new laugh back to the bus in here and we'll click. So this time this new layer is going to be called dotted. The color is going to be yellow because it's gonna be a nice thin pen on a very light dotted line on. It's going to be using a dotted line type, so we'll click onto the line type here for dotted. Click on load, go down to find dotted. Okay, so here's the dot line Time Carrie, to that. Make sure we've selected it in this style of box before we say OK, and now we've got dotted associate ID. With this line type on. The color is yellow. We're gonna add another new layer called text for annotation. So we're gonna call it text and no so new layer t x t space a double in Oh, and this time we're going to choose a green go green for text on we're gonna change the line. Type two continuous. Good. Now we've got a green pen for standard annotation and we're gonna have a sick up in for our title. Okay, so we're going to put text title, and they were gonna choose a sick a pen. And so I'm gonna choose Cyan here, Kate, and make sure it's a continuous line. We're gonna put another new layer in called Vieux Port. So up to the new layer button, click V I E w p O R t or one word. But then we're gonna choose a non standard color for our view ports. And the reason we're doing a non standard colors because we don't want it to print out black. We want it to be non printing. So if we choose ourselves a color, which is going to be very obviously different. Okay, so there's a nice color here. Number 211 and then in the plotting column, we'll click onto the printer icon on, make sure it says do not print because the view port you're gonna find out is a rectangle. You can have circular view ports if you want, but normally rectangles and you don't want them to print. You want the contents to print? Yes, but not the outline. Okay, so that's good on. Then. We're going to have I lost layer. This is going to go in, and this is gonna be called no print. And for the same reason, we're going tohave no printing, and we're gonna have another different random color. I'm gonna choose orange now the idea of having a no prints layer is so that you can leave your construction lines. Or you could put notes or annotation which are intended for either yourself or your colleagues, but not for printing out. So you could leave a note on a drawing to say this area hasn't yet. Bean agreed or approved. Or you could put some notes in there, some annotation in there that reminds you of some of the decisions that you made. Okay, so it's always good to have layer, which you can rely on to store the stuff that you don't want to delete. But you don't want to print. Okay, that's good. So now we've got these extra layers in, we're gonna close down our layers dialog box, and we're going to check out these layers. I'm going to select one of these white layers, and as you know that you can go to the properties dialog box if you like, and you can change over the properties off your line type so you can go to layer here. This is what we want to do, and we want to see what the boundary looks like. Okay, we are. We've got the boundary. That's one of the new layers that we put in and you can see from this representation here. It's circles of straight lines, which is a good way of showing your posts on your fence line escape. Now we can do this in a different way as well. We can select a line that we want to effect, and we can use this pull down list here, which is probably a little bit quicker, and we can choose our different layers here to switch over to. So let's come down a little bit further and we're gonna find out line that we put in as outlined. Click on the word outline. Don't click on any of these other buttons because they're actually active. Buttons click on the word outline. And so what was a line on? Layer zero is now a line on their outline and see it reflected here. The properties. You can see it reflected here as well. That's press escape twice. To come out of that will select the next line down, and we're gonna use this quick pull down menu to switch our layers over text annotation goes green escape. Select the next one down. We're gonna come down to text Title goes to the science color this Skype. Next one down, we're gonna go for view ports. There's a view port color and escaped. And you can see I've chosen a color which isn't quite the same as this one up here. Okay, this one is on Lehrer outline, and it's magenta. Number six on this one is a sort of a sort past early version of that. And I'm gonna select this one for no print, print and escape. And then this last one, this is gonna be our dotted line. So we're gonna go down, find dotted. We get this guy. And that means if we want this circle in the bottom right hand corner to go on dotted as well, we can select that pop this circle dotted on this guy. Okay, so we've made ourselves some new layers. Okay, we've given it some names on. We've been careful about the spelling on the names because we don't want wasted or duplicate layer names. Just because we've merged databases on we've spelled differently. One of the things that you might want to consider is that to get over this problem of duplicate layer names. If you're working in a group or you're working with colleagues in your office, agree a layer protocol early on in the project. You know the words. Sit down around the table, have a discussion, get a spreadsheet, type up what layers you're going to use. I agree the spelling on the colors that you're going to use for the layers on. Then make a template in auto cad with exactly those layers already pre made. And then you don't have to make them again. You don't have to worry about other people making spelling mistakes later on, and it all works out really nicely. 36. Bylayer Explained: Okay, so here we are in video number 33 called by Layer Explained on. If you'd like to open up the drawing number 33 By later, explained Onda, we'll have a little chat about this phrase that AutoCAD uses by layer Andi. It's a very simple concept, but when you see it, it makes a lot more sense and have a look at the drawing that we've got open in front of us so you can see that the majority of the roaring is in yellow. And some of the details that we have here are in reds and blues on white, and we're gonna find something out about that. If we hover over the colorful detail, you'll see that we have a block reference. Yeah, but this is made into a block. And over here these machine heads are also a block reference. So what's going on with the other stuff? Let's going float over top of the other stuff. Well, Polly Lines and it says the color is yellow. And if we float over something else, it says that Polly line the color is yellow. Now. This is non standard, because when you draw things normally the color will be by layer. So the standard settings, the default standard settings in order card are that everything you draw should be by less so that the layer controls the color. In other words, all of the colors are set in the layer dialogue box. Now this drawing has bean drawn where, unfortunately, the layers don't actually show the color, and the color has bean overridden in the properties dialog box. So let's just check out what's going on. I'm gonna choose one of thes lines here ons you'll see here it says color yellow in the properties dialog box. And it also says line type on DA, even though we have a layer here called Sent No. One. Now, if we go into the layers dialog box l. A and we find sent one. Okay, it says that the line type is center on. If you have a little look down this list here, you'll see this whole bunch of layers, which are various different colors on those colors, don't seem to be showing up. So let's close down the layer dollar box. What we can do here is on our layer that we had selected on a line that we had selected. We can just check out the line type and it says continuous. But in fact the default is no continuous so much as by layer. And if we switch over the line type toe by layer, then suddenly we reveal the line time that we've got set up in the layer dialog box. So the correct way of normal working is toe have everything set by layer. Okay, let's check out different colors as well. Because if we do a global select, in other words, we're gonna select absolutely everything in the drawing. If we look at the properties dialog box, the two thing that you notice varying big time okay of the line types which should be by layer. Okay. And at the top here, yellow is the predominant color. What? We noticed that. But it shouldn't be that yellow is the predominant color. It should be by layer on Suddenly, if we reveal the by layer information. Suddenly everything takes on what looks like it's proper colors because the layer dialogue boxes now in cut in charge because the color is by layer. Okay? No, it's a weird concept, but once you get used to this idea of by layer. Then suddenly everything makes sense, and you realize that the layer dialogue box should be in control. Of course, if it's not in control, then of course, it makes the management of the drawing much more difficult. So I would suggest that you adopt using the default protocol for everything which is color by layer and line type by layer. Okay, you've also got the line weight by layer on. We're gonna come over to that later, but we've got a number of things that we can rely on. So if you think that the default setting should be by layer, then that's a great idea on DA. It's probably not a good idea until you're an expert to vary that on only in some exceptional circumstances. So that's the by layer explained. And so if you want to review this video again, just go back, otherwise will meet you in the next video 37. Adding Colours to Layers: So here we are in video number 34. And this is all about adding colors. Why? We should add colors, how to ride colors and that sort of thing. Okay, so if you like to open up your drawing number 34 you can work along with me here, we've got a picture off camera, front view and back view, and all of the detail has been drawn on our default layer. Layer zero. We can just check that out. Weaken, select everything right The way across on putting a big window around everything you could use a blue window or a green window just to remind you a blue window is an enclosing window on a green window will select anything it touches. Okay. And that's called a crossing window. But once you've got everything selected, we can check out in the properties dialog box, and it says here layer zero, which means that everything you've got selected is on layer zero. Okay, good. So we're gonna come back into the drawing with our mouse press escape twice on, then we're gonna have a look at the dialog box, so l a enter and you can see here. We've got a number of pre made layers, but if we look down the colors there a lot point. So let's go through our layers. I Let's see what we've got. We've got buttons, centerline detail, lens, logo, outline and screen. So let's have a think about what colors we might like to use. Let's choose centerline first. The center line needs to be a nice, thin, crisp line. So using our color protocol that we discussed in a previous video, we would go over to where it says white and click and choose color number one and OK, and we can have a center line which you can see is dash longer. Short dash locates that. So let's see how we would apply that in the during. Now that we've got it set up and we know that it's red and dotted, we're gonna find the center lines now round by our lens. We've got four cent lines, so I'm gonna select those, and I'm going to switch everything over from layer zero to layer centerline. We can do it in the properties using this drop down box here, or if we want, we could use this drop down box as well to do the same thing so we can see very clearly that we now have read center lines, right? So that's pretty easy. Is now good now that we've sussed out how the whole thing works, if we go back to our layer dialog box, L. A. We can start making other decisions. So, for instance, the outline Let's just say that we're gonna have a nice, chunky, thick outline. We could choose Magenta because that's on the thick side. Remember all of our pen. Start thin and work up in size towards number seven. So magenta for an outline. And then we could have a detail. For instance. Let's go for the detail. Now, This wants to be a nice thin pen. Okay, so we could go for a yellow on that and still on the colors. Let's have a think about what color we want. Our buttons that here's our buttons. Click onto the white color in the button column on DA. We're gonna choose Green and then on the lens. We want some more subtle detail here, so we're going to choose a number eight. I'm for the logo. We want that to be quite striking, and we also want the logo to print in red. So I'm gonna choose color number 10 and we're going to go for an outline on the screen. That's the screen on the back of the camera, and I'm going to choose a science. So once we've agreed, those colors weaken. That goes through our drawing and weaken, switch the objects over onto those layers. So let's close that down and have a look at some buttons. Okay, his buttons on. We can switch those over onto layer buttons. Of course they go green. So it's gonna be quite easy now for you to go around select. Okay, we can put lying around any of the buttons, and if you want to check out where the outline is going to be going, we can make sure we de select anything that we've got selected here so we can choose shift de, select anything that we've accidentally selected, and then we can switch over two buttons on Skype. And here's some detail we can put that onto layer detail on escape is a bit more detail. We're gonna put that tell, as you put it onto the different layers. It takes on the different colors because everything's by layer. Now, let's have a look at our lens. We're going to select these two lines here. I'm gonna put those two on layer outline because their dominant and then I'm going to select these ones here. I'm gonna put those onto layer lens and they become less dominant. Here's our logo, and I'm gonna put that onto layer logo and I'm just gonna work around the outside of my camera. This is going to go onto the outline layer. I'm just gonna grab that all the way around using a little crossing windows. So if I miss anything out, go back onto that. The crossing window is a really easy way of selecting. And it might be worth practicing that a little bit, because even though not everything is gonna pay easily selectable, we need to make sure that we could get hold of it and select it. My sneezy. Okay, I'm gonna put that onto layer outline. Good. So the dominant information is on there. Outline is a little button I left there, so I'm gonna put that on lap. Okay. We got a bit of detail here in a bit of detail here that goes onto there detail. So you can see how quick it is that once you've got the whole bulk of your drawing drafted on land zero, then just sorting out which layer they're going to go on to is an extraordinary quick way of, ah, changing layers, for instance, using this pop down menu. So at the back here, I've got a screen. I've got a rectangle that road sense represents the screen. Like I'm just Pope all of that onto the screen. We've got a whole swathes of buttons here which we can pick up. So I'm gonna put all of these buttons onto the button there, and I can put all of these all at once onto layer button press escape. And then if I've accidentally picked up anything that should be on detail, I can just select it again and switch over until a layer detail on the same is true here for this little bit of detail here, I could use a crossing window to pick up. Should be. All of that's gonna be on detail. There it is. Being super careful is to make sure that accidentally pick up anything green. So this is a nice way of exploring or cat. Okay, This guy on detail, I'm escape so you can see that it's a very easy and quick method of making sure everything ends up being the right color. So as long as you're organized and you've got your layer protocol in place, okay. Switching over layers that you've drawn on layer zero to any other layer and just organizing your layers very quick. Very easy. Very simple. All right, so have a little play with this drawing and see what you can do to get the whole thing sorted. Okay, Make it. Making sure it looks nice on once you're happy with it. Save it and join me in the next video. 38. Adding Linetypes: So this video is all about adding line types Onda, Although that we've touched on it in previous videos. We're just going to go through the detail of it here so you can dip in a dip out. And if you want to open up the drawing number 35 adding line types, uh, we'll give this a go. Okay, great. So we're assuming at our line, types are all controlled by the layer dialog box so that we've got all of our standard settings, which means that all their lines and line types are by layer. We're gonna type in the lead command, and I'm gonna use the short cop here. Okay, a shortcut is l A. And, uh and here's my layers dialog box. You'll see. I've prepared a few layers already. Okay. And center line dash dot Ignore death points because that's an automatic or to cattle air dotted gas hidden, etcetera. And we're gonna go in and have a little practice adding these line types. So, first of all, with centerline, we're gonna follow this across to a column called Line Types. And instead of a continuous line, we're gonna go and find center from this dollar box. So centres already being preloaded, which is great that we can just click on it here and say OK, we've associate ID center with centerline. But let's have a look at dash stop because this one hasn't bean preloaded. Let's go to the continuous Andi, have a look down here now if it hasn't already been preloaded, we have to load it into the drawing before we load into our layer dialog box. So we're gonna click on load and we're going to scroll down here and find dash dot Select it and click OK, and then back here in this line type selection box, we gotta find dash dot highlighted on, then say OK, so effectively, what we're doing is we're loading it into the database and then once it's in the database, we select it for use with the current layer, okay? Or the selected lab. So let's try that again with dotted is the dotted layer. Okay, we're gonna click on line type continuous, and we're going to load in dotted so we can come down to the load button and scroll down the side here until we find dot and you'll notice that we've got 23 different types of dot We've got the standard dot we've got dot to, which is half the size. And we've got times two times two, which is twice the size. So you've got a bit of variation in the sizing. Okay to it. There, pick it up here and OK, and then we're gonna go to the gas layer. Now, this is a very slightly different type off line type, so let's come across to continuous and click on it. Find the load button and click on that on. Then we're coming down here to find gas, and you'll see that gas line has the word gas written in it. Okay, so just click on that. Choose it from this preview box on. Okay, so now gas has gas line. Okay, let's keep going Hidden. Click on continuous
