Line filtering with complicated geometry


I am working on the purlin system of a sports hall with a quite complicated geometry.

There is an edge running around the perimeter (selected - green curve).

I would like to filter the lines which run below the edge.
I have managed to do most of it, but it is not perfect, for example there is a wrong line at the top of the narrow part:

As the edge is changing in all three derections I can’t figure out how to set up a proper filtering method. (was thinking about making an edge surface with loft, and use that but I didn’t succeed)

Any ideas? :slight_smile:
Thank you!
