I have a very werid problem today. I extruded a surface in grasshopper, and then deconstructed it. But the faces I got are only 3 surfaces instead of 6. The “untrimmed surface” is considered as a single surface in GH. However, when I baked into Rhino, it showed as a polysurface, and can be exploded into 4 surfaces.
I also offsetsurface by using pythonGH, but it still happened.
