Symmetries should not require body to be centered at origin
The check in Face.cpp l109ss
if (((result[j].R() - rperp * normal) + (result[j + NE].R() - rperp * normal)).mag()
> 1e-12 * radius_2d)
throw std::runtime_error(
"Invalid polyhedral face: edge centers violate symmetry S2");
is too restrictive.
