One of my products has a complicated cut and I can never figure out the correct way to model this in 3 dimensions. I've attached a section of the 2D drawing that shows this cut along with an actual picture of what it looks like. Everything I've tried to do in the past with this cut has been very very complicated. Essentially the cut is straight for a little bit and then as you can see starts sloping up towards the base. The inside is a round, not flat, surface.
Any advice on how to model this easier than making a ton of planes, trying to line them up, and making this cut in like 5 steps?
