Trim Curves By Boundary

[dmillerSNYXQ]

I am trying to find a way to remove/trim intersecting curves. I have the ceiling outline boundary (purple color), and I would like to cut and remove the ceiling pattern that crosses the ceiling boundary.

Turn the boundary into a surface, then use a Geometry.Intersect to get only the parts of the lines which touch the surface.

Hi,

I mean, there’s actually a lot of ways to do it, but the first thing that comes to mind is something like this.

@jacob.small I am not sure where I am going wrong. I created a poly surface from the Boundary Lines and used Geometry.Intersect node but I end up with the same issue.

I got it figured out. I create a surface of the bounding lines in the wrong manner.
