Full Version: Boolean Diff

Thank you Michael for such a great cad program!

I'm just a hobbyist that did a little 2D CAD about 25 years ago as part as my work.
I'm posting (attempting to, my first post) a 3dm file.

This question is more for curiosity than anything else.
This is the first time that "Boolean Diff" didn't work for me!

I'm curious why it didn't work for me. It seems simple. Maybe I'm missing something.

I want to remove the little cubical shapes from both wheels.

Thanks for your help to satisfy my curiosity!

JoeZ

Your objects are "tangent" just increase Scale 1D and that will works! ;)

Hi JoeZ, it sounds like you've got it figured out, but yes it can be difficult for booleans to handle cases where 2 surfaces are just barely skimming each other with overlapping surface areas. That's a more difficult case for surface/surface intersection to handle.

So it is good to push objects through each other with a little clearance if possible.
