hi alex, thanks for the response. Sorry if I didnt explain my self well enough. I need to get the outline for each group of overlaped surfaces in their respective position, not in a projection to the xy plane. If I dont use projection I still have the same problem which is the region union only working for 2 of the 8 overlaping surfaces.

I think if I was able to have in each branch the surfaces that are overlapped I would be able to make region union work properly but Im not sure of how to do that..

Oh i see. i was confused by your first image3 showing the lower outline only.

anyway. if you have your tree trimmed and reverse the lists in region union component it works. don't know why though, did not look further into it.

cheers

Maybe it has to do with curve length, but i am not sure, could be case specific.
