Cut lines passing polyline

[Marcus_Isacsson]

Hi!

I guess this is an easy one.
I wonder if anyone here knows a quick way to draw a polyline along the facades then cut all lines outside of that one.
(also cut inside the “hole” in the middle)

BiMorph Curve.SolidIntersection

First, thanks again to Thomas for the updated package. This is going to make a graph I’ve been dealing with much faster. I’ve got a series of curves intersecting a solid (some fully within, others partially, some completely outside) and the Curve.SolidIntersection node works well except I’ve got one solid, and one curve out of 529 that might intersect that solid, that won’t play nice. If I yank the curve it works great but I don’t see why that curve in particular is causing the problem. Offend…

Please send a screenshot of your graph showing your specific issues.

In all honestly it looked far too complicated. I just want to cut a bunch of 2D lines by selecting the outer lines along the facade instead of cutting each single line manually.

I will also use this later on in Dynamo, projecting those lines on the roof surface.

SetIntersection for Curves

Is it possible to SetIntersection for lists of Curves? It doesn’t seem to be doing anything.
