Public Member Functions
	Select3D_SensitiveGroup (const Handle< SelectMgr_EntityOwner > &theOwnerId, const Standard_Boolean theIsMustMatchAll=Standard_True)
	Constructs an empty sensitive group object. This is a set of sensitive 3D entities. The sensitive entities will be defined using the function Add to fill the entity owner OwnerId. If MatchAll is false, nothing can be added.
