Extract Interior curves of trimmed surface with Grasshopper

[m.shcheblykin (Maksym S.)]

Dear professionals,
please advise how interior curves of such Breps can be extracted with Grasshopper

[tognatta.aditya (Mr.A.)]

Use Brep edges, Connect join curves to the Naked edges output(En),then connect the output from join curves to list item and extract the internal curves.
Hope this helps.
Mr A.
