 In this video, isometric drawings practice were asked to sketch three solids on isometric dot paper. There's a lot of approaches to drawing on isometric dot paper. I would recommend that we always start with the dimensions. And the dimensions that we use when we're working with isometric drawings is the front measure, the height, and the right measure. And so we say the front by the height by the right. Or we can shorten that up as F, that doesn't look like an F. F, H, and R, front, height, and right. For this drawing, we have a cube with an edge of five. We all know what a cube looks like. And all of the dimensions are going to be the same measure of five. So I would recommend you write out the dimensions before we begin these drawings. It's going to be five by five by five, front, height, right. The easiest way to begin this, I'm going to show you what it should look like and then walk you through it. If you want to try to draw this on your own first, why don't you pause the video and see what you can do. Otherwise, I'm going to show you the finished product and then walk through what we do to get it to look like that. So this is what it will look like, a cube with an edge of five. I'm going to write up here again, front, height, right, which I would recommend you do for all of them. And then I'll show you what a good strategy is to draw these if you're new to this. So before we begin drawing, I'm going to label this. This is my front measure right here. And in working with those Legos, you know that that represents, if you're looking at it face on, that's represented by the front. The right then would be over here, the right equals five and the height is always that vertical distance and all of these measures in a cube are going to be five. And again, there's several ways to approach these. I always start with this bottom point and I'm always going to start by making this V with the front value and the right value and then from there adding the height value. And once you have those three lines drawn, it's just a matter of kind of putting the pieces of the puzzle together. So I'm going to draw an identical cube so you can follow along with me and I'm going to start by picking a point this bottom point right here and drawing my V. I'm going to start my bottom V right here and I'm going to go front five which means I'm going to do one, two, three, four, five for my front measure, my right measure of five, one, two, three, four, five. So if I start with that V from there, I can add the height measure of five starting from this bottom point, one, two, three, four, five. So I have my front, my right, and my height. You don't have to label these. This is just to get you going if you're new to drawing these. Now that I have those three basic measures there, I can add the rest. You'll notice that each of these vertical lines have a height of five in this cube and so since I drew this first one, I can draw a height of five from each of these endpoints of the front and the right. So I'm going to go up one, two, three, four, five here and up one, two, three, four, five here. I'm always going to have those three vertical lines that have the same measure and now if you can visualize this, it's just a matter of connecting the dots. If I'm drawing a cube, this is going to be the value of my right, the five. I'm connecting here. This will be the value of my front and now this is where you want to make sure that you draw the cube. A lot of people try to connect the dots just to finish it off, but we know a cube, we're going to follow this a parallel line to this line right here and follow the dots, one, two, three, four, five and then a parallel line to that edge. Connect it down one, two, three, four, five and that's my finished cube. Some people like to put in the, kind of to give it some dimension the dotted lines like this so we can see some dimension to that three-dimensional figure. You don't need to do it. Your finished product will just look like that is just fine. So let's move on to our next one. We'll go a little quicker on the next one. We're asked to draw a rectangular prism two units high, six units long and three units wide. Again, I'm going to write my front height right just to help me out with this and make sure you're labeling these correctly. The two units high we can fill in right away is the height and then the six units long and the three units wide it does not matter which way you do that. I usually do the long one here, six and then the right will be my three. So I have a six by two by three front height right. I'm going to show you the finished product again and walk you through it. So if you want to pause and try this on your own go ahead and pause the video. Otherwise, here's what we're going to end up with. Again, we said that this is a six by two by three. So I'm going to write that down here again and I'll walk you through again. I'm starting at this bottom point. So I'm just going to start down here. Pick that bottom point. I'm going to do my front first. One, two, three, four, five, six. One, two, three, four. I just had to make sure that's six and then make the V with the right. One, two, three, and then I finish up by going up to from that starting point. One, two. So if I start off with the V and then add the height, my next step is to add the two other vertical heights from the endpoints and then I'm just going to connect the pieces like I did before. This represents, I'm just going to write the front, my right, and my height. I'm going to do the other right side, the other front side and you'll notice that those are also six and three. And then connect it out with the parallel line to my right going out three and the parallel line to my front edge of six. And there's my finished product. The last one is a little trickier. We're asked to do a triangular prism and you should have an idea of what that would look like. The bases on this are going to be triangles, but it is a prism so we're going to have two triangle bases and we have two units high. The bases are right triangles with legs three and seven units long. So again, I'm going to do my front height right. The height I like to start with because I know that that's two units high and then the front and the right, no matter what order I do that in, I'm just going to do a three and a seven for the right. Three by two by seven. Again, if you want to try that, pause the video otherwise. Here's the finished product on this one. We know that it's going to be three by two by seven. You'll see again that I'm going to start with this bottom point. I'm just going to start down here with this point. Make sure you leave yourself enough room if you can visualize what this will look like. I'm going to start with the front of three so that's my left. One, two, three. I'm going to go right seven. One, two, three, four, five, six, seven. That's my V. And then I'm going to end up going up two for my height. One, two. The next step, just like before, I'm going to add that vertical height to each of the endpoints. I'm going to go up two from each of those endpoints. And just like before, I'm going to connect the edges. This edge was seven, so I'm going to do that parallel edge right here. It is also seven. This edge was three and this parallel edge is also three. And this is where you have to be careful. It's going to be a little different from the triangle prism because this is a triangle prism. You can see that these two bases are triangles. And so, of course, they're only going to have three sides. So instead of extending out before to make a rectangle base, we want to make a triangle base and this is the one instance in these isometric sketches where you're not going to follow the lines of the dots. You're actually going to go across to connect the dots here. And so, this final line to make a triangle base, I'm just going to cut across and you'll see I'm not following the dots and that's going to make a triangle on top. You'll notice on this one that's already drawn we do fill in the dotted line to give it dimension. You do not need to do that otherwise that is my triangular prism. Notice that the bases are right triangles so I am going to go ahead and put my right triangle symbol on both of those bases to show that that is a right triangle for those two bases.
