Cabinet door question on inside 90s
 

I'm stumped on tool paths for inside corners. With this ogee bit, I ran a simple profile on a 2d square geometry. I'm using bobcad/cam for programming. I'm assuming I need to build full 3d geometry and use a tapered ball of some sort to finish corners, but would love some additional insight.

The way you think is right.

Use radius doors. You won't need to separate the corners, plus the radius doors can be opened in a variety of ways. The most popular are the usual opening, sliding (as in the closet), sliding like an accordion and others. This is what gives you the opportunity to use such doors not only in your ordinary rooms, but also in the bathroom. I personally use one of these bathroom door and it's incredibly convenient. Firstly, such doors are moved apart very widely and you have a lot of space to get out of the bath. Secondly, from the design point of view, this option looks much more attractive.
