Hi and sorry for my english.
I’ve got two subtools: the first is a sphere in the form of an head. The second is a zsphere model converted in to a mesh and moved in its position (near the middle of the first) with the transpose move.
If I try to rotate in the 3d world the whole object (not with the transpose rotate) I see that the two subtools have different pivots and one seems to penetrate the other during the rotation.
I’ve search in this forum for a solution, I’tried everything: unify, set pivot point and so on but I cannot fix the problem.
The only solution is merge the subtools and resplit in subtools again, but is not a solution for me.
Please help me! Thanks!
