XCAF problem

Grigori's picture

I tried to compare different STEP files if they have same shapes. I read them with XCAFReader then I took TopoDS_Shapes from every STEP files and compare them with operator firstShape->IsSame(secondShape) . But for the same shapes it gave me that they are different. I saw then this problem in debugger: for entities adresses different, but all the other adresses equal. And I saw in Handle_Standard_Transient.hxx file which herits TopoDS_Shape that it compares entities. So I don't know how to decide this problem.
