 Select3D_SensitiveFace (const Handle< SelectMgr_EntityOwner > &theOwnerId, const TColgp_Array1OfPnt &thePoints, const Select3D_TypeOfSensitivity theType)
 Constructs a sensitive face object defined by the owner theOwnerId, the array of points thePoints, and the sensitivity type theType. The array of points is the outer polygon of the geometric face. More...

 Checks whether the face overlaps current selecting volume. More...
 
virtual Handle< Select3D_SensitiveEntityGetConnected () override
 Originally this method intended to return sensitive entity with new location aLocation, but currently sensitive entities do not hold a location, instead HasLocation() and Location() methods call corresponding entity owner's methods. Thus all entities returned by GetConnected() share the same location propagated from corresponding selectable object. You must redefine this function for any type of sensitive entity which can accept another connected sensitive entity. More...
