Most CADs support to extend face by specifying some edges in the face. After reading through the occ doc, I only find a API GeomLib::ExtendSurfByLength. Yes, it works well for edges lied on ISO direction. However, this API is totally based on geometry but not topology. I wonder know whether occ supports to extend face by edges or wire. If it does not, can anyone give me some suggestions to extend face properly.
Thanks in advance.
