For this tutorial we are using this retangla box or cube box to see. So you are bending your wrist, your pants, your set square and your protractor. So first thing, you have to draw a line across your paper. Now help. So when drawing a line, so that the line width will be the same. You roll your pants so I'll draw a line. The next thing, you have to draw a perpendicular line. To that line you draw across your paper. The perpendicular line. It does a 90 degree. So your paper. The next thing, since it is isometric, touchy degree. But side, so you measure touchy degree with your protractor. Never mind, you can't construct it with a degree if you want. For this tutorial we are using a protractor. Then draw a line connecting that point you must to the center where that perpendicular line cuts the line you drew across your paper. Do that for the other point also. So touchy degree, touchy degree, since it is isometric. From that picture I should add the stats. One side, this side is 7.7 mm. That's 7 cm. The reason this is 7.8 cm. And this side is... Hmm. It's 4 cm. Sorry. So you draw a line parallel to it on those points you mark the 7.7 mm point and the 14 mm point. So do that to use your set square to transfer or draw a line parallel to it. You know that your ruler does not shake and set square does not shake. So you do that for the other side too. Without shaking your ruler once you set that if shake, you realize not the way it is supposed to be. Go back, start from the beginning to get it. So I've been done that. The next thing to do is to take the height of the cube board and thus 15 mm. You take it for all the three sides of the measure. Connect them together. Try to be perfect in every time you do so I can get the accurately resolved. So to get the other points you can use your set square to draw a parallel line on the other dots. The opposite dots point the other. You do that for this side. You do that point there. And draw a line. So you notice you have a parallel line to that line. They do that for this side also. So you can have a parallel line. Now I've been done that. I've been doing them either in the canal or outside line. The purpose of making them light at the beginning is that it is easier to erase those construction lines. Unlike when you've outlined them to make your work neat and to avoid too much errors. First use construction lines and at the end outside. By then you must have been sure that all lines are correct. We are correctly drawn so to see. So we've gotten to the end. This brings us to the end of this video.
