MO,

Rebuild Surface option is a great addition to your node,
however is there a way to ensure that the rebuilding maintains the orientation of the original surfaces?

If you look at image below, the combination of "Join" & "separateObj" (green nodes) should unify normals (if not already), however the resulting vector array is not directionally consistent.

PS: I had assumed that "INVERT" option would flip the surface normals, but it does not appears to have that effect. Is it doing something else?
