I have a shape that I want to cut only the gray area (not the inner rectangle). Is there a good way to do this?
Also, I'd like to have sharp corners on the gray rectangle's outer edge but I'm using a 1/2" spiral. What's the best way to accomplish this? I know there will be outset .250" radius cuts outside of the rectangle in each corner. That's ok, but I'm not sure how to accomplish this.
The objective is to be able to put a sharp cornered insert into the gray area. So the outset .250" in each corner is ok. I just need to know how to do it.
So I guess that's two questions:
1. How to only cut the gray area rectangle and leave out the white.
and
2. How to allow for a sharp cornered mating part to fit into the gray area (how do I avoid radiused corners that'll prevent the mating sharp cornered part fitment)?
