Outline generation/Region union of coplanar lattice surfaces

Hi! I have made three overlapping polysurfaces from voronoi diagram. Trying to create outlines of three surfaces. Region union seems to ignore blank spaces in these lattice surfaces.

How about Graft and Entwine?

Hi! Thank you for your time, I am looking for a way to create a single polysurface/mesh from these three coplaner polysurfaces.


I got your expected result using a Solid Union, the downpoint is that is takes nearly 30 seconds to compute.

Get a typical - real-time- solution for the 2 Brep Trees (I could add the 3rd - or any others - obviously).
