Hello,

I have a function that return an array of edges of an selected part on an assembly document

            Component2 comp = (Component2)uA.swSelMgr.GetSelectedObject6(1, -1);

            double len = 0;
           
            if (comp != null)
            {

                Body2 SwBody = (Body2)comp.GetBody();
                int n = SwBody.GetEdgeCount();
                Array AllEdges = (Array)SwBody.GetEdges();

               for (int i = 0; i < n; i++)
                {
                    Edge e = AllEdges.GetValue(i) as Edge;

                    ...

                }

             }

Now I  need it to work on a part document, but the comp.GetBody() always returns null.

I tried to differentiate the two components:

               if (swModel.GetType() == (int)SolidWorks.Interop.swconst.swDocumentTypes_e.swDocASSEMBLY)
                    comp = (Component2)uA.swSelMgr.GetSelectedObject6(1, -1);
               else if (swModel.GetType() == (int)SolidWorks.Interop.swconst.swDocumentTypes_e.swDocPART)
                    comp = swRootComp;

But I got the same problem.

Is there any other way to get the edges of the  part?

Thank you.
