Does anyone know if it's possible to identify the coordinates of the faces given a feature name of a part? That is, given a feature name "Cut-Extrude5" or "Mirror4", is there a function that could return the faces associated with that feature? I'm guessing that to retrieve the coordinates, a different API function may need to be called.
Depending of what coordinates of face you are trying to find. You can evaluate the face to get its coordinates (IFace::GetSurface->ISurface::Evaluate) or you might want to get the bounding box of the face: 2012 SOLIDWORKS API Help - GetBox Method (IFace2)
