I tried to copy a couple of holes of that polysurface via the
! _CopyHole command, but something prevents Rhino from doing so. The
! _MoveHole _Copy=_No command does not work, either.
However, these two commands eventually worked when I used the
! _ExtractSrf command to extract some surface off the polysurface, then I joined them together again. Only then I was able to copy the holes I needed. Looks like some hidden force “locks” the ability to copy or move holes in this polysurface unless it’s being modified.
Can’t move the holes of this polysurface.3dm (137.5 KB)
