We prove that it is strongly NP-complete to decide whether a given orthogonal
polyhedron has a (nonoverlapping) edge unfolding. The result holds even when
the polyhedron is topologically convex, i.e., is homeomorphic to a sphere, has
faces that are homeomorphic to disks, and where every two faces share at most
