The idea is to do this for hole wizard features only - if a designer makes a clearance hole with an extruded cut or if the hole is in imported geometry, we don't think it would be feasible to check. I don't think it's likely easy to make even just focusing on hole wizard holes, but the basic concept sounds like it could be possible?
So essentially:
- Does this kind of thing exist in any form - macro or purchased tool/plugin or thing that does something similar and could be modified?
- If it doesn't exist, is it likely something that could be made? Or is there an obvious roadblock that would make it not worth trying?
