it seems that Sage can't do this; moreover, none of its geometry backends support nonconvex polyhedra. There aren't many options if you want off the shelf software supporting these. Nef polyhedra in 2D and 3D are supported by CGAL (the latter does not have an interface to Sage AFAIK). I am not aware of anything else (although I imagine there is a lot of CAD software that can deal with these in dimensions 2 and 3) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
