Additional data for entities

Gerhard Hofmann's picture

Hi everybody!

I would like to add additional data to TopoDS_Shape objects. It seems there is no way or did I miss something? If I want to gain the structure of a Shape (like in Fig. 10 of "Modeling Data User's Guide") it is difficult to find out whether two wires use the same edge. The iterator or explorer only yields the values of the edge, not the identity (of course you can compare the values). "TopoDS_Iterator".myShapes.current probably contains the address of the edge, but it is private and I dont want to change the source code. And I don't know whether the edge is reallocated when the shape is moved or rotated.

Any idea?

Thanks for any hint!
