IFGraph_Articulations Class Reference

this class gives entities which are Articulation points in a whole Model or in a sub-part An Articulation Point divides the graph in two (or more) disconnected sub-graphs Identifying Articulation Points allows improving efficiency of spliting a set of Entities into sub-sets More...
