I'd like to get some advice on how to extend many lines

Extend_Line.gh (16.1 KB)

Hello, thank you always for the forum.

I’m writing because I have something I want to get advice from.

I’m thinking about how to extend it like the attached picture using several lines, but I don’t have a clue about the solution, so I’d like to ask for your advice.

Please advise if there is a good way.

But this doesn’t solve all issues, such as what to do about overlapping lines.

there is no good way better than your way. The better advice is you implement the rules you want. Because I don’t see which logic for that

I gave a try with Gilbert Tessellation but, I didn’t cut the curves at the intersection

Slightly better with 2 tesselations

The way I want is to modify the existing line, and it wasn’t to make a new line. Thanks for your reply!

Let me think about it again.

Thank you for your answer.
I think I need to make my thoughts more concrete.

Ok, so I think the best is you make a program, a bit like Gilbert Tessellation (the sources are visible) and you tune it for your need.

What’s the point of starting with curves that already intersect? Use the geometry that was presented in the first post where the line segments don’t touch each other.

I think it’s a good attempt, but I don’t think it’s the result I want.

To explain further, it is the centerline extracted from the Steel Frame drawing, and it is an attempt to obtain the boundaries of the deck plate.

Check this , in the result there are very little surfaces you can cull them based on their areas or you can use polyline collapse

You need fennec addon to use Regions component
