About This Class

Learn to design and model furniture with Onshape. Aimed at beginners, in this class we build upon the skills learned in my first two classes which focused on the basics of CAD. Now by using those skills, we model a coffee table and make a drawing to help us in the workshop! This is not necessarily a woodworking class so we won’t be touching much on how to fabricate the table but we’ll make sure to consider that part while we’re designing. This is the first of a series of woodworking focused lessons so hop in and enjoy! Part 2 of the woodworking series is here

Onshape is free for hobbyists, makers and students. It's also cloud-based so there is nothing to download or install and it only requires a decent internet connection so no need for a powerful computer. Make an account here : https://www.onshape.com/en/products/free

Hi I'm Math! Welcome to my classes

Teacher

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

Transcripts

1. Introduction: Hi and welcome back to my own shapes series. So in the previous lessons, we focused on the core functionalities and tools in non shaped to get a better understanding of the basics. Now we'll be moving towards more practical projects. In this class, we'll be modeling a wooden coffee table and making a drawing that could help you actually build the table. As always, I tried to give you tips and tricks along the way and hopefully you'll learn how you can use this free software to design furniture and create drawings to help you in the workshop. Thanks and have fun. 2. Table of content: Okay, so before we begin, I just wanted to let you know that this class is part of a two-part series on woodworking. So this is part one. This is tableware building. And this is the table will be building in part 2. So in this one we'll be exploring the tools that we can apply to woodworking. And we'll also be making a 2D drawing to help us build the table in the workshop. Now part 2, we'll be focusing mostly on how to model different joiners. So we'll be looking at easy ways that we can model different types of joints in on shape. Both of these classes also follow my more broader cat basics class width on shape. So if you haven't checked them out, you really should check at least part one because this is where I explained what exactly is on shape, how it works, the different controls, and what basically is CAD. If you already know all of that, then jump right into this one. But if you don't, I'm not necessarily going over all that stuff again in this class. So they're worth your time to check the previous ones if you want to follow along this one more easily. So make sure to check out the previous classes if you haven't already. And after this one, make sure to check out part two where we explored join y3. And so now we can get going. 3. Making the table top: All right, welcome back. So this is a table we're going to be modelling today. It's based off of this design that I found on the Internet, although I simply scaled it down. So it's a coffee table instead of a dining table. So as usual, let's start from a fresh brush studio. So the first thing we're going to be modelling is the tabletop. So let's do that on the top plane. So let's do a sketch here. Let's remove that. And the tabletop is as simple as it gets. It's simply a rectangle. So let's do debt. Like I showed you the dimensions or 400 by a thousand. And let's simply extrude that as a, It's able to up here. So a neat little trickier. Let's say you're juggling both imperial and metric and you decide to build or you bought a one inch thick tabletop, instead of trying to input 25 0.4 millimeters from one inch, you can simply go one inch here, press Enter, and there you go. So as you can see on shape automatically put 25 0.4. So we're going to use this trick a little bit in this part, but I wanted to show you it's really neat. 4. Sketching, extruding and mirroring the legs: Well, the next part here will be the legs. And since the legs are offset from the ends, will need to build a new plane here, roughly here. So let's use the plane command and it's offset it from this face the other way around by about a 100. Let's start with that. We'll come back and change it if we're unhappy with it. So we've got our new plane here. So we'll draw a sketch. There you go. So if we come back and take a look at the legs here, obviously they're symmetrical. So the only part we have to draw is this part here. So let's go ahead and do that. So let's start by drawing our lines and I'll just draw the general shape here. And afterwards I'll come back and add the different constraints and dimensions. Um, I think that's the easiest way to do it. Gives you a good idea of the rough shape. Everything is blue though, so we're going to have to work our way around the different constraints and dimensions. So the first one I'm going to put is this one here. And you remember I I inputted one inch here for the tabletop, even though my whole document is in metric, I could still go back and change the whole document to imperial. But I think it's nice to juggle the two because sadly in some places of the world, that's how it is. And also something that I haven't really mentioned is that you can use math in these boxes here. So let's say that while designing this, I decided that I wanted this here to be 1.5 times the thickness of my tabletop. So I can go ahead and write 1.5 times. Then the thickness of my tabletop was one inch. And then he goes on shape knows how to do basic math, saves us from doing it ourselves. So I'm just going to use all of this and move it like that. Next dimension I want is this here to here. So this, I wanted to be roughly 16. Yes. So this is ugly, but we'll get to it. Next one. I want the angle here to be 105. There you go. So obviously I want these two to be parallel. So parallel it. Next thing I want to work out is this here. So if you remember correctly from this, so the area here is a bit thinner than up here, so there's a slight taper there. So we're going to call that. And let's use math again. So three-quarters times one inch. There you go. So there's something here that really bugs me. So I want those two points here to be in line, and I'll use the vertical here. So that helps. And then I want to work out the angle of this leg here. So I'll simply select this line here and go like that. No inputs, 75. So in both cases I'm using 15 degrees off of 90. And then we should probably input the overall height of this thing. Move from here to here. That would be roughly 400, then it's managed this whole thing here. So I want this point here to be in the middle of this here. So I want the joint to be here. So an easy way to do this would be to use the construction line, which you already know how to do. And this point becomes the midpoint, 30 volts. So. Now you can see what it does here. And I want, I want this section to be the same thickness as this one. So this line in this one, if they are equal. So we still have some blue and we can still do that. So basically the question is, how do we want to divide our shapes? So let's simply use the rule of thirds. So from here to here, that's called at 400 divided by 3. Here we go. And now if we look at this here, we can see that this is one part and then the middle stretcher is a different part. So we're going to build our sketch the same way. So instead of having this go right up to here and then using the mirror, we're going to stop it somewhere here. Because this is how it's done in the image 40 here. And then I'm going to add another section here like that. Make sure this gets into, there you go. And that's our sketch. We are going to use the mirror once this is extruded and I'll show you why. So we can close it now. Okay, so now we've closed our sketched. It looks like I'll just hide this plane here. And let's start extruding. So let's start building our different legs. So let's use the extrude here and we'll start with this face. And I want it to go the other way around. And I'll extrude an inch again. So if I use the Azure, remember correctly the ad would merge the leg with the tabletop. I don't want that because it's a different part. So when you, There you go. So my second menu part is here. I'll leave that on and then I'll use this area here to extrude the middle. So once again, the other way around and it's the inputting a length. I'll just use this face here. And I'll make sure I'm using a new part because I don't want to merge. There you go. So I've got a third part here. Let's call that, okay. Now we have a quarter of our legs. So let's start mirroring. So we'll use the extrude number three and then the mirror function. And so the entities to mirror. Here we go. Mirror plane, errant case will be the front plane. And now I won't add, so I don't want a new plant, new part I want to add. So the middle part, I want it to be one piece. So I wanted to merge with Part 3. So this is good. Okay, So now before I mirror this image here, if we go back to our original design, the corners are rounded here. So I'll do that to make sure this function transfers to the other one. Well we mirror. And so instead of doing it in the sketch, I'll just use the fill IT tool. Could have done it in the sketch. Both are fine. I just find it easier to work with fillets because then I have a specific function here in my tree that I can go back and modify easily instead of having to go back and modify the whole sketch. But both would work. I think 4040 looks good. Thank, let's use 40. Okay, so now I can go ahead and mirror this whole thing. So I'll be marrying that with the front plane again. There you have it. So we have our leg assembly and then obviously we need something to on the other side. So we're going to mirror that again. So what, we're going to mirror it, this, this, and this. All three using the right plane. There you go. I don't want to add on what new. And there you have it. So we've got our main table assembly. So the only thing we're missing here is a stretcher. So we'll do that in the next video. 5. Adding the stretcher, a chamfer and some color: So while the stretcher, we're gonna do a simple sketch on the right plane here. So sketch here. And the only thing we really want is basically a small rectangle here. So I'll just draw it at, and now I'll use the sketch number two to help us. So if I select these points, this line here, and use symmetric. Now, if I go like this, so I'm making sure my, my rectangle here is centered in this area. So I'll do the same thing here. So this Blaine, this line, this point metric once again. So now I have a rectangle that's centered. So let's put our dimensions here. So I want this to be about ten. And this ten as well. Simple. So let's accept our sketch. Let's hide this one and use our sketch. Extrude. There it is. So first direction, blind know we went up to face, this face here. We want to make sure we want something new. And then to go the other way around, we'll use a second end position. And then up to face as well. Select this face. So we're making a new part. We've got part number 8 here. We're not adding, we're not merging. Here we go. And there you have it. So our basis solid now. So we've used a chamfer tool before, but this time we're going to be using it in a slightly different way. So let's select the four lower edges. And I'll show you. So let's just use this view here. So by default, a chamfer is a 45 degree angle, and then you specify the distance. So she wanted bigger, it's 10, but it's always a 45 degree angle unless we decide to specify our own distance and our own angle. So let's use 40 here. So that's 40 would be here and quite a big distance, but we want a shallower angle, so 20. And that's what it looks like. Well, let's just accept and see what it looks like. So as you can see, this adds a small finishing touch to our table top. And obviously we could play with these different parameters. You could have a even smaller angle, tan, or maybe a bigger 130. Um, I think 20 looks good. So this is just a different way to use the chamfer tool. Quite useful, adds a small nice detail for a finishing touch to the tabletop. We could have done this feature differently, but I think it's much easier with the chamfer tool. So there you go. Nice, easy and effective coffee table. The last thing we could do to clean up our drawing is maybe add appearance. So if we want our legs on the darker side and our tabletop, maybe on the lighter side. Knows. So that doesn't look half bad. And there you have it. 6. Drawing template and main assembly: So if you plan on building that table or anything else for that matter, it might be useful to make a drawing like this one. So let's do that right now. So the first thing we're going to do is start a new drawing. So create a drawing. So the first option we have is the different templates. So let's click here and see what drawing templates on shape has. As you can see, we have a choice of ansi and ISO. And C is a bit more and North American, and ISO is mostly the rest of the world. So for example here a four is the sheet format. So you might be familiar with A4 is the most common, 14 are North Americans. A would be the 8.5 by 11 sheet that you normalcy. So as you move down a, B, C, and D, the sheet gets bigger and it's the other way around in ISO. So a4 is smaller than a3 and a2 and so on. So I'll choose this one for our purposes. So let's click. Okay. So this is what we agree with. The first thing we're going to do is insert the main assembly, the main table. So we may, I did it in my module number 4 and I'm going to include the parts of the whole part studio. So let's just use that. And I'll change my scale here. So I want it a bit bigger. So let's say when a, that looks good and I'll put this one here. And if I keep moving, it will automatically add the different views. So my side view, and if I go back to this one and might help you as well. And just for the example, I could use this here to add a bottom view if I wanted to. Okay, so now we have our three main views. The drawing environment here works a bit like a sketch does. So I can use the same shortcut D to input dimensions. So I could say like this, like that. And the overhaul, ie like that. So with these two dimensions, I can cut my tabletop to S1 is mostly for reference as the height will be impacted by the legs. And we'll do a second sheet for the legs only for the tabletop. I could add a couple of dimensions depending on how you want to build it. This angle could be useful for the table saw, for example. And then possibly here. So I think with these two dimensions, you'd be alright to make this chamfer here. The other thing I'm going to add is the placement of the legs. So from here to here, that's a 100. And since I know my assembly is all symmetric, I don't need to add a 100 here. But what could help it also is this dimension here for the main stretcher. But personally, I would probably install both legs and then measured at distance instead of relying on the drawing here, but here it is anyways, so this gives us the overall dimensions here for the assembly. So next we'll make a second drawing for more details about the legs here. 7. Detailed drawing of the legs: So from this sheet will add the second one by clicking here and then inserting a sheet. And then we'll need to insert a view. So by default, I still have this table here. So I'll go into the Insert menu here, choose my part studio, and then choose the leg here. And then the skill I think 13 could work. Yes. And I don't want the front view. I want the right view. There you go. So I'll put this right here. So from this you, Let's add a couple dimensions. This here could be useful. And same as this. So if you remember correctly, when we drew those parts, I was juggling between metric and imperial. And I'll show you a trick here so I could use inches instead. So this is 1.5 inches and this year is. So three-quarters or I could use fractional here. There we go. So even though the whole document is in metric, we can still insert some inches if you need to. So I'll continue my dimensioning here. This one is in inches again. So if I go to make this shape, I'll need to know what the overall dimension of my my stock needs to be. So if I select the here you are. So I know that if I make a stock that's 400, but by, let's say 136, I've got enough wood to make this shape here. And another one that would be useful. It's the midpoint here. There we go. And then from there correctly, we're using angles here. So that can be useful. Same thing here, 75, but then with the different fillets that we have here, it makes it difficult for us to find the intersection of these different corners. So what we can do is use the original sketch we had. So if I click on Show Hide Sketches and Sketch Number 2. So let's write that. So as you can see, we now have our original sketch before we added the fillets. So we have a couple of ways that we could add dimensions. If for one, I think that we have enough information here to figure out how to draw this thing here. But if you want to help yourself, obviously, nothing stops you from adding this dimension, for example, or anything else just to help you out. Now, one thing that these sketch at it is this section here, if you remember correctly, we use that for the middle part now just to make sure we don't mess up and include it in our, in our leg. Let's just add a note that says ignore this. So now we know we have to ignore this because I think it would be quite easy to just go ahead and make the whole thing out of wood. But then you wouldn't need a massive piece of wood for that. Which would be kind of a bummer. So we're at, we're adding a small note here, just, just, just as a reminder. So next thing we could do is use this available space here to include the middle part. So let's insert another view. Click on Insert here, and then go back to a part studio and use part number three. And I'll use the right view and place it right here. And since both the leg and the middle stretcher use the same thickness and use the front view as well to input the thickness. So adding dimensions, I'll put it here. And then here, then we remember that this is in prerenal failure are both being in Imperial. So when I look at this, those two numbers kinda jump away. There's no way I'm going to go to that kind of precision. I end the workshop and it works well in the cab. But one thing I could do is just reduce the precision here, or let's call it 133, because that's probably what I would aim for anyways. In here, maybe 135 or 136. There you go. So that's probably a bit more realistic in terms of what you can achieve. And we still have an available amount of space here and I'm going to use it for something that will help us. So I think that with these dimensions here, these angle and all of that, It's fairly easy to build this rectangular shape, but the radius is a bit more difficult to get. One thing we do know is that our radius is 40. So what we could do is use this space here to make a circle that's 40. This way when we print our drawing, we would have something that's 40. We could just cut and then use it as a template when we're drawing. And now sadly, on shape doesn't allow us to make a sketch in the drawing. But what we can do is that I went back to my studio and then I did a sketchier, which is simply a 40 mils circle. I put a you can put it wherever you want. I'll just hide it here. And then when I go back to my drawing, I can insert here another view and I can use the sketch. So in my parts to join on before I have a sketch and I have this one. But the really important thing here is that our whole sheet is in 1 third scale. So I'll use a different one that we'll use 11 because that's what I want for this view. And There we go. So since the scale, it's different for this view automatically there is a 11 scale here and a that appears. We could put the diameter just for us. So going back, if I print this, even though it's 1 third scale and I can't really use this as a template. I think d dimensions here are good enough for us to draw that full-scale. And then we could cut this around and then use it to make the different radii here. So another thing we could do for this area, for the radius. Let me just clean this because we're going to need space num of that a bit, is use a detail view instead. So detailed works like that, makes a circle. So we just go like this. And then it makes a detailed view or that. So if we come back and make sure that we have a one on one scale. So yeah, we might have to move some stuff here. Let's put that in the corner, then move this here. And there you go. So since this is one-to-one, if you print it and cut it, then you would have a perfect template, either out of cardboard or paper to make sure your joint respects this general shape. Obviously, if you had the printer for it, you could scale this up on a bigger sheet, two-way 11 scale and then simply use it as a template. But for me I think that's just simpler and easier. So that's what I go for. 8. Exporting as PDF and wrap up: Now the only thing missing would be to export that as PDFs for us to print. So right-click here and then export. And then I could give it a filename. So it's table here from it as PDF and export. And then once you have exported it, you will get a document with both sheets as a PDF that you can print or do whatever else you want, and there you have it. So in our case, this drawing is for us, it's for us to use. So if you feel like you need a one more dimension, like, like this one, even though it's it would be redundant, which go right ahead and do so whatever you feel like you might need, Hugh could, for example, add a note to make sure that you make two of those. Two. And you need for growth just to help you up. So drawings can be a bit intimidating at first because there's tons of rules, unwritten ones, best practices and all of that. But really, if there's drawings for you, Who cares, add whatever you need, whatever you feel like you might need more than less so you don't have to come back and yeah, have fun in practice. All right. Thank you for making it this far. I hope you enjoyed it and that you'll learn something if you want to learn more, be sure to check out Part 2 of this class, we'll be building this table slash credenza. The main focus of the class will be on different joiners. So we have bridal joints, half laps, blinds, rabbits, all the good stuff. So be sure to check it out if you're interested. And thanks again for joining me.
