select edges on a Element Form

[Anonymous]

I have a problem in Revit2020 in the adaptive family component.
When I create an Element Form generated from a section  and a segment I want to select the edges of the solid but it doesn't snap on the edge, it gives me just the full form element without any option about edges.
I link a screenshot of the problem.
