On this line we can make measurements that are flat, not in perspective and then use the measuring points to bring those flat measurements back in perspective. We use this to construct the two equal front sides of a square. Once we have that we can take the back corners to the vanishing points to get all four sides of the square. When we draw an ellipse in this square we have our master ellipse. Let's start from the beginning and do this in detail. First we will add the horizontal measuring line. In the station point layer of the Paths panel. Add a horizontal line high up in your project. Click once to one side. Hold down the Shift key + click again on the other side to make sure its horizontal. We're getting a lot of lines. So I'm going to mark this, horizontal measuring line. The horizontal measuring…
