3D Voronoi on Brep

Hello my name is Josh and I am really struggling with getting a 3d voronoi structure within my brep. I have gotten the brep to be split into individual cut out polysurfaces but it will not create the web like structure I am looking for. I will attach a picture of my rhino file and a picture of what I actually want it to look like

Here is the script I am using to generate the individual cells

Try this. I deconstruct each cell, extract the faces as polylines, scale with the face center, then loft between those two.

That creates a bounding box around my brep, however I am trying to get the voronoi structure to be contained within my brep so it still holds the same form. Attached is a picture of what I get with your script applied to my brep.

The 3D voronoi only works within a bounding box. You would have to do a boolean intersection operation between the brep and the structure (try converting them to meshes first). I tried some other things to avoid this necessity, like doing the boolean before the edge extraction and offset, but if the brep is curved, then you could have a curved cell face whose edges aren't planar. Then all of a sudden it's a much more complex problem.
