Im trying to do a voronoi façade on my subd volume. How can I transform my SUBD multipipe to NURBS?

Here’s a simple script (1 line):

subD_to_brep.gh (88.4 KB)

It just calls the RhinoCommon SubD.ToBrep(SubDToBrepOptions) method with the supplied options.

maybe there is something that i am not understandig. I am geting a brep output in the exemple, but i actually need a surface output. Am I letting something pass?

A brep can be a single surface or a polysurface. In this case, it is probably a polysurface (multiple surfaces joined together).

The script output should be the same as baking your SubD to Rhino and running the _ToNURBS command.

So i cant transform subd multipipes to surface?

It is not possible to make a branching structure like the one in your picture from a single surface.

Your multipipe structure can be converted from SubD to a brep but it will be a polysurface (multiple joined surfaces).
