    How to access selected edges respectively?

    Kasun Udayanga

      Number of edges in a model are selected before run the macro. When the macro is run ,it should iterate through each and every edge separately. I will include another  program in that loop which will create points on that edges. Sample model which have selected edges is attached herewith too.

          You need to use GetSelectedObjectCount2 Method (ISelectionMgr) in combination with GetSelectedObject6 Method (ISelectionMgr) to process all selected edges.


          Links to sample macros can be found here,

              Thanks for your information. But i do not get clear picture about how to do it. BR.

                I have tried with two Methods which you have mentioned. But it failed to give required functionality. I have inserted the VBcode used for the macro too.

                Best Regards.
