Hello students. In this video you'll be learning how to draw an isometric cylinder. To begin this we need to draw a basic isometric cube. The one shown here is a 2x2x2 cube. At this time please pause the video and draw the cube. If you need help with drawing the cube please refer to the isometric drawing cube via the video located on the L drive. Now that you have your cube drawn the goal of this activity is to build a cylinder inside of the isometric cube. So that the isometric cylinder has the same qualities. Let's begin by going ahead and drawing the grid lines that are on the top of the cube. To do this all you're going to do is take your protractor and measure an inch from the top and repeat on the parallel axis. There's one of my two lines. I'm going to repeat on the other axis. As you can see on the top of our base shape we've created a grid. This will help us to draw our circle later on. We now need to repeat the same process on the bottom. To be able to do this we need to define the back edges of the lower surface. To do this we're simply going to take the corners and measure a 30 degree line from there. I'm going to set my protractor on the corner and find that here is my 30 degree. It should line up with the line that you drew earlier. The distance will be two inches just like everything else we've done. That will take you from corner to corner. Now what I'm going to do is repeat on the other side. Now I've created the lower back surface and now I can use these four lines to create the same grid as I did on the top. Let's go ahead and begin that. There is one of the grid lines. Now I'm going to repeat the process in the opposite direction. Now I have grid lines on the upper and lower surface of our cube. Now it's a matter of sketching in a circle. I'm page 105 in your textbook, Gateway to Engineering. You'll see that there is a diagram that takes you through this similar process. At this point we've done the setup process which is in step one. Now we're moving into step two, sketching the top circle and bottom. Realistically this is four arcs broken up by those lines. What we're going to do here is start my sketching process. The arcs always start with some portion of them on the straight line and follow it. So I've gone ahead and basically get a rough idea of what I want. You'll notice that I work from both directions. I meet in the middle. What you're seeing me doing is I'm rotating my papers. I do this. It just makes it easier to draw. What I do is I check to see how much distance I left and that way I can keep my sides fairly even. So at that point I have the top circle drawn in. Now I'm going to repeat the process on the lower surface. I'm going to do this. I'm going to do this. At this point you'll see that both circles have been drawn. It's now a matter in step three of just adding in the lines. Simply come in here and create a line that is tangent to both circles. I'm going to repeat on the other side. At this point we've created our cylinder. Really the last step is to go through and to remove the lines. If you draw on them light enough at this point they should be fairly easy to remove. So lines being removed you get a true sense of the cylinder. Have a fun drawing the isometric cylinder.
