Hi! I have a 3D model (please find attache) composed of a 3D sketch that looks like a wireframe structure. I'd like to extrude each quadrilateral formed by this structure to create multiple separate solids (each solid would represent a sheet).

The problem is that I can't seem to extrude directly or create surfaces from these quadrilaterals. Of course, I could create additional planes and redraw 2D sketches
