Recently I want to select the primitives as circle, cylinder surface or something else. Do the OCC have some specific functions to let me to this so? Or something else I can do? All I know is that Using the AISContext->ActivateStandardMode(TopAbs_Type); But in the TopAbs_Type there are only TopAbs_Edge and TopAbs_Face, but not what I need. Can someone help me out?
Ask something about the selecting mode
