Hi I'm Math! Welcome to my classes


Hi! I'm Math, and I'm a mechanical engineer (but that's the boring part). I'm also a maker, fixer, tinkerer, whatever you want to call it : I love building random things. I've built stuff ranging from a massive industrial vacuum forming machine to a bike frame, and everything in between. I love gaining new skills and every time I do, I feel like I'm unlocking a whole new set of projects that I can tackle.

In that spirit, I want to pay it forward by sharing the knowledge I've gained over the years in my studies, work and projects so that more people can enjoy making stuff. More importantly, I want people to do it mindfully, with the right knowledge and safely. So my classes are focused on developing good practices and acquiring a more profound knowledge of the underlying principle... See full profile

1. Introduction: Hi everyone. My name is Matt and welcome to my class. My goal with this series is to share some of the knowledge I've gained through my career as a mechanical engineer. So computer-aided design, or CAD for short, is a really powerful tool that can enable you to design, model, or create a multitude of objects or assemblies. You can use it to 3D print a bar, model furniture invents something you are even redesign your kitchen, the list goes on really. Most CAD softwares are based on the similar concept. And this is what I want to teach you with this class. We'll use onsite, which is a free software for makers. It runs in your browser, so nothing to download or install. It also runs on your phone. And I'll use it to teach you the basics of can so that you have the tools and knowledge to accomplish your specific goals and projects. This is a two-part series. The first one goes through the basics of sketching and extruding. The second one explores the revolve sweep loft and thickened tools to create more complex shapes and parts. If you want to explore further, I also have two classes that they, these concepts in the real-world by applying CAD to woodworking. So check them out if you're interested. With that being said, thanks a lot for joining. I hope you enjoyed the class and I'll see you on the other side. 2. What's Onshape and how to use if for free: So what exactly is on shape along shape is a CAD program. You can use it to build simple stuff like this. You can make drawings like these ones. You can make funny-looking tables and all sorts of things. So the main feature datasets on shape apart from the other ones, you might have heard of, Solid Works, Fusion 360, maybe Creo, all of them. They all require you to download a software and install it on your computer. Most of them don't run on Mac. And you kinda need a good computer or a powerful computer for them to run properly on shape runs in your browser. So it's Cloud-based and browser-based. If you've ever used Google Docs, it's exactly the same thing. Nothing to download. You simply make an account, log onto on shape on any computer at even worked on your phone, there's a nap, any browser, and you can use on shape. So as I've said previously, you can actually use on shape for free. So if you go into on-chip webpage and click on pricing here, and then scroll down all the way down. There is a hobbyist and maker public plan. So basically, they allow you to use on shaper free for non-commercial purposes and all your data is public. So if you're fine with that, then you can use on shape for free. So in public plan and you'd get started, you simply make an account, follow the steps. You've probably made accounts before for other stuff, It's the same thing. So now that you've made and confirm your account, you simply sign in and it will bring you to your main dashboard and non shape. So this is what it looks like. If yours is new, this will be empty. Otherwise, this is where you'll find all your previous parts, your previous assemblies, everything is in there. So if you want to create a new part, simply click on Create and a document. You can go give it a title and create. So this is your new document. We'll go through these controls much deeper in the next chapters in the next videos. Right now there's two things I want to show you. First of all, are the controls. So if you click to my account and go to Preferences, you can customize the units, but more importantly, the mouse controls. So I come from a SOLIDWORKS background. So it's really nice that I can use the Solid Works controls. You can also try the unshaded controls. Doesn't really matter as long as you get comfortable with what each button does or each combination of button does in the specific controls you decide to use. So what these controls allow you to do is to rotate a part, zoom in, zoom out, and then pan, which means moving apart. Another thing I want to show you is that as you can see, no save buttons and non shape. So as I've mentioned previously, it works pretty much like Google Docs does so well, since everything is in the Cloud and your browser, every move you make, every modification you make is automatically saved up. So we never have to click save or anything and you won't lose anything. And on top of that, if you click here, every change you've ever made, every version you've ever made are all automatically saved here. So we can go back in time to a previous version or a previous movie you did. So that can become useful if you'll work on really complicated stuff. So that's one of the really nice things about on shape. First of all, it never crashed on me, not yet. And on top of that, everything is saved up automatically. So for me, this is a really big pulse of working with this one. 3. The Onshape controls and environment: All right, so before we start, I just wanted to show you a bit the unshaded environment. So it kinda works like Excel does with different tabs. And you can easily create different tabs here. So this is a part, so I mean the part studio, if I want to build in another part that's related to this one and just created another part studio NFL want to put those two together. I can create here, an assembly here, and I created that. So I can put This birth and the other one together. That's also where you would create a drawing. So from the part Studio one, I created a drawing here. So I'm in the drawing environment here. So that's pretty much it. You can think of it the same way you do with Excel. So if you're in this environment here right now, the different tabs are different parts or different assemblies are different drawings that are related to what you're doing right now. And if you want to build something completely different that's not related, then you would create a new document instead. 4. The CAD elevator pitch: So here is a real quick, real basic rundown of how cad works. And that applies to most of the different CAD programs. You could find they mostly all work the same. So you have a different couple options to create a solid. And I'll show you a really simple example for all of them and behind all of them, the same principle is that you start from a 2D sketch and then you use whatever 3D tool you want to create that solid. And this is also how you remove material. You use the exact same functions, but instead of adding it, creating material, you simply remove it. So the first one is the Extrude. I've got an extrude here. So what I did is a simple sketch. You can see it here. I've got basically two squares with rounded corners. And I took this sketch here, this area, and then I use the extrude function to create that solid here. So if I look at the extrude function, I can have last or more material like this. So it's a bit like if you were to push play-doh through my sketch here. So that's how you use extrude function. The second function you can use for greater solid is the revolve function. So this one is also simple. You create a sketch. So that's what I have here. I have a sketch like that. And then you use that sketch, and then you define an axis like I did here. And then it revolves. In this case, I made a 360 revolve, but you can make a partial revolve. You simply take your sketch and then turn it around an axis, and that's how you create a solid. The next one is a sweep. This one is very easy to understand and you start from a sketch. So in this case it's this simple line here. And then you add a profile. So in my case, we have a round, so super simple profile. And then with this sweet function, you take your profile and then you run it down your trajectory to create a solid. So very simple. The next one is called left. So in this one you have a minimum of two sketches. The first one I have is a circle there, and then the other one is an ellipse like this, but you can add sketches as much as you want. And then the left function creates a solid by joining those two pieces and you have a couple different options you can use. And then last but not least is D thickened tool. So this one works a bit differently. You first create a surface. So my surface here as 0 thickness. This is a tool used in CAD and then as the name implies, the thickened will take your surface and the thick end for misspecified thickness to create a solid. So that's the basic rundown of how cab works, really simple. So in part 1 of the class that you're currently doing, we'll be focusing mostly on how to sketch because it's really at the base of everything we do. So we'll spend some time there. Then afterwards we'll look at the extrude function to create our first solid. And then we'll play with different controls and everything just so we can have a feel of on-chip, not in part 2, we'll be constructing a bit more complex parts and we'll be focusing on all the other creating tools that we have in on shape. So we'll be using the revolve sweep loft and thick and tools to create more complex shapes. 5. Sketching basics: So before we can learn to run, we actually need to learn how to walk. So in this case, it means learning how to sketch. So as I've just shown you, in order to create a 3D object and on shape. And in most of the different softwares for that matter, you start from a 2D sketch and then use one of these features to create an object. And so let's take a look at the sketching basics so that we can lay a solid foundation. So I'll sketches are easy to do. You select the plane you want to sketch on. So let's say we use the top one and then click Sketch. If you want to bring this gets normal to review. You can click the End key and then if I use the P key, it removes the plane. So now I have a clean sheet. So as you can see, we have different tools and what we had in the 3D environment. And so I would separate these tools into three different categories. So you have the creating tools, you have the modifying tools, and then you have the dimensions and constraints. And one thing to note is that most of them have a shortcut. So I'll usually say what tool I'm going to use, but maybe I won't be clicking it because I'm using the shortcut just so you know, but let's say you want to create a line, so we put it online and then simply click drag and you have a line, and then by default you're still in the line tool, so you're creating a new line so we can continue and then create our shape. And so we've closed the shape here, but we're still in the line tool. If you want to escape that line tools simply press escape. And so now these lines are all free to move wherever I want them to move, and I can even select the point and do something. So in the next thing you want to do in your sketch is that dimensions and constraints. So let's say you're a dimension. So I click Dimension and then I select this line, and I bring you a dimension here. So let's say I wanted this one to measure 60. And so now this one is 60. And I can select the line, or I can also select these two points and create a dimension between these two points and call that 150. So this is a smart dimensioning tools. Usually it knows what you're trying to dimension. So if I want to create an angle here and knows that I want to create an integral so I can call that 75. And this added a new dimension, Let's say this one. So as you see, this one is great. It's not the same colors as the other ones. So what a great dimension means is that it's actually unnecessary. So since this is 6150 and then I have an angle here, I don't need to add a dimension to this line. It has to be 133, 0.9 to three in order to respect the other dimensions I've already put there. So you can have it for convenience, but it's actually unnecessary. So let's just remove it so I can click and delete. But now one thing I can still do is move my shape around. So the reason for that is that it's not fixed at all in space. So in every new part, you always have an origin, or at this point here is always fixed in space. So it's a fixed point in space. And you're going to build peace or your part of your assembly around this fixed origin. You always need a point that is fixed somewhere. Otherwise, you could always move stuff like that. So if you want to fix your sketch and space, you need to reference it to either the origin or something that is already fixed in space. So let's say I want this corner and the origin to be exactly the same spot so I can select both of them. And instead of putting a dimension of 0. I can go in my different constraints and then use coincident. So now as you see, my corner is on the origin and something else happened. Now my sketches black. It's not what that means is that my sketch is fully constrained. So if I try to move something around, I cannot. If I want to move this, I cannot. It's all fixed in space because I have my dimensions here, the angle there and I fixed the corner there. My sketch is fully constrained and I felt more to remove something like that. Now I have part of it that is fully constrained, but part of it is not. I have this thing here. They can still move. So I changed my mind. And I don't want a 75 degree that I mentioned. Instead, I want these two to be squared so I can use the perpendicular. And there you go. And one thing to note as well, Let's go back to the Line Tool. When I drew this line here, it snaps into place and do the horizontal. And if you check just below my arrow where my mouse is, there is a small horizontal line. It means that if I draw this line like that, it will automatically add a horizontal constraint to what I'm doing. Whereas if I go like that, it doesn't have the horizontal constraint. So if I go back down, you seek on a snaps into place and there's a bit of play there, so it snaps into horizontal. It also snaps into vertical. So if I go like this, it snap into horizontal. I create my line and then I go like that. It snaps into vertical. So not only is this one horizontal and this one vertical, these two are perpendicular to each other. And that's what happened to my Skechers. That's why I didn't need to add the horizontal and vertical constraint to these two lines. Okay? And so now let's say I want to select these two lines and delete them. I can obviously click and click and delete, but you have different ways to select things in on shape. So if I click and drag to the right, you can see I'm making the blue rectangle. And so if I select things like this, you'll see that only this line was selected. And the reason is that when you click and drag to the right, it selects objects are things that are fully enclosed in this query you're making. So in this case, it's only this line. If I unselect that and I go left instead, you see I'm making a yellow square. So in this case, what it does is that it will select anything that crosses the yellow square. So in this case, these two lines were selected. So let's do that again. If I select the whole thing, both of them will be selected. If I select only that, even though I'm crossing the horizontal one, I'm only selecting the vertical one. And then like that, even though I'm fully enclosing none of them, I'm touching two of them. So both of them are selected. So let me delete that and that for that matter as well, so we can check the other tools. So obviously you have line, you also have a circle, for example, that's quite easy to do. And then you add a dimension. There you go. You've got a fully constraint circle. I put it on my origin and then put a dimension. So there it is now. So that's what these tools do. So these are how you create shapes. I won't go through all of them. I think it would be a waste of time. But just know that when there is an arrow means that there's more than one tool and that area. So there's two ways to build a rectangle from the corner or from the center. And the same thing for the other ones. So go ahead and explore them. They are really simple to use, but let's take a look at how we can also. Use these tools or modifying. So let's say I have a line that goes like this and I put a dimension and I say seven. Okay, so now I have a fully constraint sketch. It's black, that's good, That's really important. But now since I added the line, I don't want this left area of the circle, so I can use the trim tool and then trim this here. Okay, Let's do that again, just so we get the idea for, let's say I have a line like that and I use the trim again, and I want to trim this. But now since this one was unconstrained, it's still blue. I can still move things around, but that's a very useful tool to trim tool. Let's go ahead and remove all of that. So I'll show you two more tools. Let's say you're building a line like this, and then a circle like this, that's good. And then we can use the trim, the trim this. And then we can use the offset tool. So this one here. And what it does is if you click Align, it moves that line from a specific distance. So in this case it's five, or we could choose 8 and then let's use it again. Well, let's click the arrow so it's the other way around and then click and say eight again. So what it does is it offsetted my line by eight millimeters to the right and then another time to the left. And this works with any shape. So I can also use the offset tool on the circle here. So offset five, that's good. And so from there we could actually finish the sketch. So let's say we close this line here. We say this and this art coincident. This, it's still moving. So I'll just good that with the origin and now I need a diameter for my circle. I also need a dimension here. So whenever you're not sure where you need a dimension, the easiest thing is to grab whatever is blue and then try and pull it in direction so you can see what degree of freedom you still have. So in this case, this needs to become incident. And then this, well, this would need to be horizontal. And so now I have a closed area, but it's not really useful because I have lines in the middle. So I'll select this line and make it as a construction line. So a construction line is a tool in our sketching. But when we exit our sketch and use the 3D tools, the construction line is not taken into account. It's really just a tool for our sketching. And so now in order to finish our sketch, we could trim this piece and this piece. And then we would have something that's a bit more reasonable and actually could function to real-world. So we have some kind of ping-pong bracket or something like that. But you get the point. That's how I use the offset and trim tools not Let's remove all of that and then let's use another one that's really important. That's the mirror tool. So let's say you're building a square and this area, and then you want to mirror that square root. So that's really simple. In our case, you can draw a line like this, make it a construction line, so it won't be taken into account. And then you select your sketch. So Mirror tool, it says so like a mirror line, usually like your line. There you go. So now you have a mirror. If you move this and this, the other one will move exactly the same way. So let's remove that. So I think you get the point. Obviously, I didn't show you all of them because I don't think it would be that useful thing to best ways actually to play with these controls and learn them by yourself. But when I learned gada really wish from one to two minutes just to explain what I just showed you because it's actually a real time saver. So a quick recap. You have your sketching tools. So those are the one used to create shapes. So just take a few moments to get accustomed to them, see what's available. Arcs for examples, polygons, you can use splines, points, text, and then this one will use it and part two of my class. So we'll get to it eventually. And then these modifying tools as well get accustomed to them. They're all super easy to use and I try to use them in my class, so we'll get back to them later. And then very importantly, the dimensioning tool and then the constraint dual soil constraints. There you go. This is what's available. You have a lot of them and they are really important. So the reason your constraints are real important and your dimensions as well is that it's really, really important as you move forward that your sketch is fully constrained and dimension. So this, for example, is not good. She move forward with that. You'll be able to build something, but it will be unstable and likely to crash or do something crazy in the near future. And what I mean is that since you're not telling on shape, what dimension you want this line to be, for example, or that the student needs to be perpendicular, or that this line needs to be whatever dimension from the origin. If you don't tell them on shape that, then this solution is as good as dissolution for on shape or for that matter, this solution is also good when I mean is that as you build your part, your piece of software needs to reconstruct and regenerate everything from the top. So if you have something that is unconstrained, then the software needs to guess where it needs to go. And so like I said, if it's guessing, well, this square, it could be like this, or it could be like this. It doesn't know the difference. But for you if the square is this big, maybe it breaks or hold assembly or your whole part. So it's really important when you're sketching to make sure that you put a dimension here. You put a dimension here. And you have something that looks like that, where your sketches fully black. If there's still blue somewhere, you need to come back and fix it before you move on. It will still work, but it's very bad practice and it's a bad reflux that have that you leave stuff that is blue. On the other hand, it's really good practice and it's really important to make sure that everything is fixed into place. That way you'll have stable assemblies, they will part. You want to have bugs are crazy things happening because trust me, whenever you do CAD, sometimes you have crazy stuff happening. And this is one of the reasons why. So avoid that at all costs. Develop good reflexes and make sure your sketch is fully constrained before you move on. 6. Extruding our first part: Okay, so now we can start working on our first 3D part. So we'll be modeling this bottle opener here. It's a simple object, but it will allow us to put into practice what we've just seen in the sketching lesson and also start using the different 3D tools that we have here at our disposition. So I'll start from a new part studio just so we can build it together. So the first thing we'll be doing is a sketch. So let's do that on the top line. So I'll just bring that normal and then remove the planes. And so as a good practice, It's always interesting to think how you're going to sketch your part relative to your origins. So as we've seen, the origin here is fixed. So we'll be building something super simple. It's only one part, so it wouldn't really matter where we put our drawing and where we sketch it relative to the origin. But as a good practice and to develop the reflex, always like to center my parts around the origin and that way I can use the different planes. My advantage if I need to mirror something for example. And so that's what I'll do here. So I'll start by drawing a line. And I'll put that line centered around my origin here. So I'll use the midpoint constraint. So as you can see, I can do this, then I'll give it a dimension, Something around a 100. Now remember the dimensions here aren't really important because anyways, we could come back and change them. And really it's just for the example. So if you're more familiar with interests, for example, just go with that and try to make something that looks reasonably well. So from that line I'll construct the handle by using the offset command. So five on one side and then five on the other side as well. So I obviously could have done a rectangle or a center rectangle around my origin, but I only need it to be close on this end. So I prefer to do it this way, but there's usually way more than one way to reach the same end result. So I'll just select these three points and make them vertical. And I'll do the same here. Critical, well, so I'm fully constrained here. I'll add a line to this end again. So now I'll draw the opening here. So I'll start with a line and I'll put it somewhere like this and then somewhere like that. So I'll be drawing only half and then I'll use the mirror tool to make the rest of it. So I'll add a radius here. Pretty hefty one night to him. That sounds reasonable. Okay. Then that's OK. And now we need to constrain this so I can still move it like this. So that's the degrees of freedom. I have. This point and this point are in line. They were put there automatically when I drew my line. So what I'll do is control the distance from there to there and call it 30. Okay? And then now I have still a degree of freedom. So this area here, as we can see, it's the length of this line, so I'll just maybe put six here. Okay, So now I'm fully constrained. This looks good. Once again, dimensions don't really matter. So I'll go ahead and select all of this and then mirror it. So I'll use the left drag, select this mirror, and then select a mirror line. So this one. And there you are quite simple. Okay, So now I'll be selecting all of this and then offsetting to the inside maybe something like two millimeters. And so I have a couple of things that are free have this point here. So I'll put it in line with the origin there. You'll know it's black. And then I'll add a line from here to here, and then this one, I'll call it 25. Okay, there you go. So this is our first catch. We'll go ahead and extrude that and then we'll move forward to add the remaining features. So we can go ahead and select our sketch and then click Extrude. And now we can see that we are extruding or in Sketch. So first of all, we're going to control the thickness. So it will be four in our case. And now the way this is setup right now, it's doing a blind extrude. So it's going from my sketch plane and then pushing four millimeters. I want to have it centered around the origin, so I'll use symmetric instead. So what you can see is that my sketch is in the middle, and then it's adding two millimeters each side to reach the 40 millimeters that I want. So I'll go right ahead and accept that. So we're missing two things here, the hole and then the feature here for the cap. And now obviously the whole, I could have included it in our main sketch, but I wanted to show you that you can sketch from any face and on shape. So let's isolate this face here and then usually sketch. So now I can bring this normal Joyce circle semicircle is in line with the origin. And then I'll simply added dimension six and then say six like this. And there you go, I'm fully constrained. And so this sketch is on the surface here of my part. And when doing these kinds of sketches, you can use the different edges of the part behind as reference points for your dimensions and constraints. So we can go ahead and accept that. And then from that sketch will use the extrude again, but we're not going to be adding material. That's not what we want. We want to remove material. So we'll go right ahead and remove. And then we don't need to specify any kind of distance. We can simply select through all, until now my hole goes through all the material that it can find. And in this case, it's the handle layer, so we can accept that. And there you go. That's one way to remove material and on shape. And so now we'll be adding the small feature here. 7. Adding a feature: So if we go back to my original part, the reason I did not include this part and the main sketch is that it's not the same thickness. So I'll need to make a new sketch and a new extrude in order to do that. So going back here, we can use the top plane again, which if you remember correctly, is in the middle of our part and so we can sketch. And so this is a fairly simple sketch. I'll just do it like this and then I'll add constraint. Like I said, I can use the edges behind that and then I'll add a small arc. So I'll be doing this, something like that. Then the radius, it's called 5, that sounds good. And then I still have a degree of freedom that can move. So I will just add a dimension, so three. So that's good. And then I'll just mirror this. So I'll select the front plane and then the mirror, and then they'll select this and this. Well, this is another reason why it's good to have your piece centered around the origin. I could use the front plane here without having to add a line in my sketch in order to mirror something. But now let's say I want the feature to go like this instead. So what I'll do is add a line like this. And then they'll just make sure that these two are coincident. And then maybe you haven't noticed automatically my Align was put tangent to my arc and that's exactly what I want. So that's good. I'll leave that. But just in case I could also do it like this. Click coincident, and then make sure that these two are tangent. So you don't necessarily have to rely on the automatic constraints that are put for you. You can also easily control them, okay? And now these lines can be put as construction because I don't really need them to be solid. Okay. And I'll just finish the sketch. So I'll put it in line there and a line there. Okay, So now my area is shaded, area is closed. So that's good. I'll just accept my sketch. And now I can extrude that. And obviously that's not what I want. So once again, we'll go symmetric and then we want something a little bit smaller than what we had before. So now let's say just two millimeters. And that looks good. And also what we're doing here is that we're adding material. So this feature here will merge. So there's a merge scope. It merges with part one, which is our bottle opener. So this feature here merges with part one and it becomes part of it. So we're not creating a new part for just merging and new feature with the one we already had. And so that's what the Add feature does here, so we can accept, and there you go. So that's the basic shape for our part. But I do think it looks weird. So let's just go back to our sketch and use the fact that we can easily changed dimensions. So this one, let's say, just needs to be a slightly bit smaller. So 75. And also maybe we say, man just needs to be five. So let's do that. So let's check what it looks like. Okay, so now it looks good. That's the beauty of doing cat in parametric. We can easily come back and change different dimensions. Ok, so now in the next video we'll be adding finishing touches and then playing with the order of operation in our feature tree to see how it impacts the part. So let's do that right now. 8. Adding fillets and moving things in the feature tree: Alright, so if we want to add some finishing touches, so one good way to do that is to soften the edges and we can do that with the affiliate tool. So that's a fairly easy tool to use. You simply select an edge and then it applies a fill it. Right now it's five millimeters, that's too big. Let's just put one for the example and then we can go around our part and select the different edges we want this one, okay, So I went around by default and then I'll add this, and I'll add this. So that's quite simple. I'll do the same on the other side. And then this. Okay, So that's super easy. Let's take a look at the result. Here you go. So you have a nice realm, fill it here, so it softens the edges a bit. So that's nice and it's also super easy to use. And so let's say we want to also add a radius to this area here and then the corner there. So let's do that. We'll select this line and then it went ahead and selected the whole face. So that's good. I'll do the same thing here. And then same thing in the corner. And in the corner here. So let's accept, and there you go. So this one looks really good. And this one, I don't think it looks too good. And the reason behind that is that when we say like the the line, we already had the fillets here. And so the fillets here broke down the nice face we had into three different segments. And so now our fill it is broken down into three different segments as well. So one way to change that if you don't like that, Like I do, is to simply change the order of operation so we can select, Fill it to, and then move it above, fill it one. And let's take a look at what it does now. So this looks much better in my mind. So let's say we come back to full it to which is now above, fill it one, and look at what we have. So since we now select this edge before fill it one exists, we now have only one edge here. And the same thing for the corner here, it's only one edge. And then afterwards, as it updates, I think now it looks better. So it's a bit more continuous. I know it's really a small detail, but it's also to show you that you can move things around in your tree and it does have an impact. And then one thing to note if you want to move things around is that you cannot move things above something that its reference to. So let me explain that. So for example, Extrude 2 is constructed with Sketch do, and then sketch do is made on the surface of Extrude one. So if you want to move, sketch do when Extrude 2 above extrude one, it's simply would not work because these two need these two above them in order to exist. So if you want to move them above, it just doesn't work. But on the other hand, Jonah, move Extrude 2 to the bottom of your list. You can absolutely do that because nothing else is referencing on Extrude 2. It's just a whole. So as long as it's below sketch too, and that sketch do is below sketch one and extrude one. You're good, you can move things around like that. But I know this is a really simple Bart might not make a lot of sense to talk about this kinda stuff right now, but I think it's important to know that. And then as you move forward and you make more complicated stuff, you might want to move things around for different reasons. And so now you know what you have to think about if you want to do that. 9. Modifying features and exporting for 3D printing: So as you've seen here, my workflow was pretty continuous and linear. I didn't really have to come back in the past and modify previous sketches in order to make my part work. But that's because I've built this part before. I knew where I was going and what I wanted to show you with the truth about CAD is you'll always be going back and forth. So as you move forward, it's absolutely normal that you would go back and change things and modify things that you had done previously as maybe you change your mind or maybe you didn't think of something beforehand. So that is absolutely normal. And obviously as you get better, maybe do it less and less because you get better at planning stuff ahead. But the beauty of gases that you can't actually very easily come back to sketch one if you wanted to. Changing, I mentioned if you need to. So let me show you an example of how you can come back and modify stuff. And so say that now all of a sudden you want to 3D print this part. So you look at it, you say That's fine, but there's this area here. So this part will have to be printed on supports because it overhangs. So that's one way to do it. It's fine. It's a bottle opener. It won't see much stress in its life. So you could go this route. What you could decide also is to bring this area here down to the same level of this surface here. So all of this is printed and you don't need support. So that would make this part here stronger. And so you really don't have to sketch anything in this way. What we can do mistakes sketch number three and then change it from the top plane and select this face instead. And so now my sketch move from the top line to this surface here. So now we can see it down there instead. Now in this case, as we moved our sketch, we have the exact same geometry, so it was able to regenerate that sketch. Now in some cases, it might mean that you might have to come back and then change a few dimensions or constraints in order for it to work. But in most cases at least you won't have to redo the whole thing. So now if we accept our new sketch, now we have something weird because we need to check out the extrude. So let's go back to extrude. And instead of using a symmetric here, we can use blinding and then the other way around. So let's go to the arrow and two millimeter it. So that sounds good, that's reasonable. So we can accept and take a look at the result. Now if you want to 3D print this, for example, that is much easier to print and will probably be stronger. So that's another way you can come back and change things in your feature tree. So let's say you're ready to 3D print that. You need to export an SDL. So you right-click on your part Studio, click export, and then simply select SDL, which you can easily export and put in your 3D printer. And there you have it. That's our finished part for the class. So a recap of what we've learned. We've learned how to create a sketch, how to use dimensions and constraints. So we'll go ahead and explore the different tools in the sketching environment. But always remember to develop the good reflex of fully constraining and dimensioning your sketch before you move on. And then we've learned how to extrude a sketch into a part. How to remove material out to add a feature like you fill it, and then move things around in our feature tree to modify things a bit. Now with all of that being said, I highly encourage you to go check out Part 2 of this class. So in this one we've mainly focused on sketching and extruding, but as you know, many different ways to create a part in on shape. So these controls are up top. And so in part 2 we'll be exploring all of them and then creating more complex shapes and parts so that we cover most of the basics of cutting. Also, if you want something more applied, I've got a two-part woodworking series which explore furniture design using the tools we've just seen a non shape. So if that's up your alley, Go check it out. So that's all for me today. Thank you very much for joining. Be sure to share your projects with everyone and I hope to see you soon again.
