* - \a dist is a some value that is computed according to the center of mass of given shape;
* - \a functor is a numerical functor value
*
* The numerical functor is computed according to the shape's topological properties as follows:
- * - orientation for vertices
+ * - orientation for vertices
* - length for edges and wires
* - area for faces and shells
* - volume for solids, compounds, compsolids
* \retval bool Returns false if the shape has no faces, i.e. impossible to build triangulation.
