This is probably a very simple question but if scripting multiple commands together on an object, how do you keep it selected when the object changes?
Run BooleanUnion on two solids then MergeAllCoplanarFaces on the result.
! _BooleanUnion _Pause _MergeAllCoplanarFaces
Won’t work because the union results in a new solid so when the second command runs nothing is selected. I thought _SelPrev might do it, but it won’t presumably because the result is a “new” object.
