Auto CPlane inconsistency with blocks

Thanks for the reply. I’m not sure what that advanced setting does or should do?

It would be nice if the AutoCPlane was aligned with the block plane.

Gumball (Object) shows the expected alignment for all five blocks which means there’s a discrepancy between the alignment of the Gumball normal and the Auto CPlane normal for some of the blocks in my file.

Maybe the Auto CPlane command needs an option ‘Align to Block’?
