I’ve been working with Rhino for years so this is a really silly situation. I’m working with a moderately big file but nothing too large. When I try and boolean, the cuts are just not accurate. The photo I’ve attached is post cut. I’m trying to boolean two solid polysurfaces. The green is the body I’m subtracting from and the pink is what I’m subtracting with. I’m doing this to maybe 30 parts at a time. Some are accurate while others are quite off. Please advise.
It is difficult to impossible to diagnose a problem like you describe without a .3dm file with an example of geometry which does not work properly. No need to upload all the geometry. Export an example or two and upload the file.
You’re totally right. Here’s a file with the issue.

Hi Chris - if I understand what you are doing, and I may not, I’d subtract from the full round green thing.
At the tolerance in the file, which is very large compared to the objects, that could be what you are doing and getting that result.
The radius of the holes in the small round things is .01, which is ytour file tolerance. Tolerance should be 1/10 of the smallest ‘feature’, at the largest, as a general rule.

AH! That makes so much sense! Thank you so much Pascal!
