Boolean difference leaving bumps

[Anonymous]

I'm trying to cut a hole on that object, but after playing around with the boolean difference that's the best/sharp cut I can get, it leaves some small bumps in the corners.

Any tips for this case ?

Thanks

Simple trick:

If you do a BooleanDifference object A minus object B run EDIT/GenerateFaceGroups on object B first (defaults should do the job)

This hardens the edges for BooleanDifference.

Hi

Although it's not perfect it seems to get a better cut, still few minor bumps but i guess i can live with them.

Thanks
