Hi, we all know why I’m here haha.
Each outside points draws a line to the center of the room (Violet room). If it touches a red room(red curve), it trims itself (Green Line remains). On the diagram, I show an example of what I want to do for 1 point.

I’m attaching to this file a rhino with a minimum number of points and a rhino file with the inputs imbedded.

Your red curves consist of overlapping duplicate fragments.

I can delete the duplicate fragments, what problems does it create?

One more question if I may ask, how do I also include the lines that didn’t touch the red walls?
