hello,
i have created several shapes and added them to my document with
Handle(XCAFDoc_ShapeTool) myAssembly = XCAFDoc_DocumentTool::ShapeTool(m_hDoc->Main());
TDF_Label lblNewPart = myAssembly->NewShape();
myAssembly->AddComponent(lblNewPart, lblShape, TopLoc_Location(transf));
Now I want to group the created Labels in a hierarchical structure. I tried to do this with
myAssembly->AddComponent(lblParent, lblNewPart, TopLoc_Location());
myAssembly->UpdateAssembly(lblParent);
but somehow this doesn't work, if lblParent is already part of another assembly. Is there another way to build a hierarchical assembly structure in xde?
Regards

Hello Göran,
if you add bottom-up then you don't have to update assemblies. Maybe this code snippet will help...
TopoDS_Shape s1 = BRepPrimAPI_MakeBox(gp_Pnt(0, 0, 0), gp_Pnt(10, 30, 20));
TopoDS_Shape s2 = BRepPrimAPI_MakeBox(gp_Pnt(50, 50, 50), gp_Pnt(10, 20, 20));
TopoDS_Shape s3 = BRepPrimAPI_MakeBox(gp_Pnt(0, 0, 0), gp_Pnt(-10, -20, -20));
TopoDS_Shape s4 = BRepBuilderAPI_MakeEdge(gp_Lin(gp_Pnt(0,0,100), gp_Dir(1, 0, 0)), gp_Pnt(-100, 0, 100), gp_Pnt(-50,0,100));

Thank you for your help, I corrected my code now. The problem was that I built the assembly structure top-down and open cascade seemed to have a problem if an assembly was modified after adding it to another assembly.

AFAIR building the assembly top-down will also work as long as you do the updating (on each assembly level)
