When you draw cuts, you have to keep in mind your vanishing points, even if the cut edges go in a completely different direction. A bevel cut is easy: just draw the profile line and send guides to the vanishing point. For a cut at a right angle, you can still send points to the vanishing point, but you also need to find the end point using a vertical line. And what if it’s not a right-angle cut? You still send lines from all points to the vanishing point, but now you drop verticals from the inne
