I’m trying to trace this box I made in Roblox to better help with the rest of the drawing’s perspective but I can’t put the ruler on 2 of the corners without it rounding to the nearest 90° and skipping directly over the 2nd corner.

Also I beg if anybody here knows how, please respond instead of assuming someone else already has, this is my 3rd time posting this and nobody has responded 🙏
