Hi Michael,

thanks for your detailed comment.

Well, still pretty new to MOI and therefore
I'm still making lot of mistakes.

I also saw the problem of thight corners and nonplanar surfaces, but I don't know
how to fix the areas you adressed. And I thought, even on thight coners, that a
value of 0.0001 would give at least a very very little fillet.

I think, the way I modeled this was completely wrong.
So for this kind of object, which way would be the best to model?

(Its just a phantasy object which has not to be accurate and which shape
grows from step to step.)

regards
MIke
