I’d like to analyse a shape and identify some ‘shapes’ within it for CNC production. I want to find the shapes that are either rebates/pockets or holes to be drilled.
The border is easy enough using DupFaceBorder, and it even turns up the inner cutouts/holes. But I’m unsure how to find the depth of those holes cutouts. Does it go all the way through? 5mm deep? 12mm deep?
I wondered if there was a way to explode the surface and sift through uncapped cylinders, etc. but I’m sure there is a much more sophisticated way of doing it.
Using the attached as an example, I’d like to create 2D geometry where the end result layers would be as per the following.
