Hi, everyone! Newbie here. I'm working on some box shapes in perspective. What I want to do is sculpt the corners of my rectangle on the side that's facing the viewer. But I want to be sure that the corners I'm cutting are being cut the same. So that if this was a real box you could walk to both sides, take a measuring tape and find them to be cut on the same angle and be the same length etc. But since my rectangle is not sitting over a centered vanishing point, I can't just measure the same angle on both sides.
I tried to figure it out myself, and I'm hoping that I succeeded. Hopefully my steps are clear! If anyone could confirm that I did this right, or let me know if I made a misstep, I would appreciate greatly!
Thanks!
