How to use brep edges as voronoi boundary

[Birk_Binnard]

You are correct - I didn’t understand that you wanted a separate Voronoi inside each rectangle. The only way I can imagine doing that is to use each individual rectangle as the boundary for a 3D surface and then use that as the input surface on the GH file I supplied. But then you’d have to re-assemble all the individual Voronois into a single piece. Plus, each individual Vornoi would be very tiny indeed.
