Hole, no hole, hole?

Postby OldDraftsman » Thu Dec 06, 2018 8:48 pm

OK, this is weird -- I think. I have 2 adjoining bodies and I put a cylinder overlapping them and Pad it Symmetrical to Plane. All good. But when I try to put a smaller cylinder inside the other and Cut, it does not fully open through one object. I tried using Subtractive Cylinder and still no good.

It does not want to cut the vertical walls, yet, it does project the Cyinders into both objects.
Is it something I am not doing?

I've found with booleans that sometimes working on them in a newly created file separate from the current project and then merging them back to the latter solves the problem.

Thanks, I went to the underlying object and created a partial hole. That will be good enough as it is only for water to enter. But, I feel the partial hole might not be an intentional "feature." :)

Everything ok here. The subrtactive cylinder starts in Body001 at a height of 28 mm and goes all through the bigger cylinder.

Please note, that it does not affect the other body!
