guys, i am stuck by trying to extract a intact surface from a unioned brep.
I got a lot of identical boxes which were adjacent . then I chose some of them to do solid union. so I got a variety of boxes. When I deconstructed them, I guess i can get complete faces which are unioned. however, it just showed original faces.
for instance, there is a unioned brep from two boxes. i want to get the surface from 6 after deconstructed it. but it actually have 10.
how can i get the surface i want?
