Odd Shell behaviour

Hello Community,

I noticed some some odd behaviour using the Shell command. If I shell the part in the attached file to a wall thickness of 1 (by removing the flat surface on top) everything works fine. However, if I Shell at a smaller wall thickness (0.1), the Shell fails to create a solid. I didn’t bother to find the threshold though :grin:. The failed shell can easily be corrected, so no big deal, but I’m just wondering if someone can shine some light on this behaviour.

Cheers,

Jan

Hi Jan - so far this works at all the thicknesses I’ve tested. I see that the original has a seam from the cylinder in it though, which unecessarily splits that face into two:

If you untrim that face and rotate the cylinder a little to get the seam out of the way

you can simplify. This should not affect shelling but may be worth a try.

Hi Pascal,

Thanks for the advice! The Shell command still failed, but only in joining the surfaces. This is easily solved by exploding and joining, and everything is fine.

I heard you are leaving McNeel. Thanks for all the support you gave me! You were always very quick to reply to any problem I had!
