Get Curves Inside Perimeter of Slab

[ZJRODGERS]

Hey everyone im trying to get just the internal openings of a slab. Right now when i get the curves it includes the outside of the slab. I also dont what to filter the lines by length because on a different project there could be more angle in the slab edge creating short lines.

RETURNS ALL PERIMETER CURVES:

WHAT I WANT TO GET:

Hey Akli! thanks for the response. One Problem with element.sketch is that it doesnt pick up shaft openings. is there a way to make it pick up the shaft openings?

Element.Location+ de clockwork

You used a different node to get the sketch lines. I have never used the one you have but the Springs node groups the line segments into closed loops. that could be your problem. The list structure between the two nods could also be the problem.
