Hello, I wonder if you can help me. I have stumbled on finding a way to organize the points coming from “Curve.IntersectAll” from Bimorph package. I am trying to allow the user to sketch a number of lines in any sequence. Then grab the intersecting point from the lines and finally draw a closed po…

[image] zakim: Sorry to trouble you with a last question: when I used your Python script inside my overall all project I am working on, the Python does not produce the required list of point to generate the polygon. Because it’s a bug :upside_down_face:, the script did not work in some cases…

Perhaps draw the convex hull of the collection of points, pull each point to the hull, find the parameter of each point on the hull, and use that to sort the points?

Thank you. Does that come with specific Dynamo package. How do I do that.

Hmmm…! I am after the Red boundary… [forum7]

Now use a Geometry.ClosestPointTo node to find the point on the polygon from each of the original points. Then use a Curve.PointAtParameter to provide a key to use as the sort order of the original points.

@Vikram_Subbaiah Thanks a lot, the related post is very helpful… I am getting close to to this :tired_face:, especially it works, no errors and it creates non-intersecting closed curves. But the resulting closed curve is not what it is supposed to be… My goal of this project is to find the correct…

Out of curiosity, why are you approaching it this way? Would it be easier to get the closest intersecting curve to each starting curve instead? What is the larger workflow for?

Hello @jacob.small … well, may be I am not approaching correct! Or there could be a better method as you suggested. The big picture is that these random lines represent column grids created a project which had been placed at different sequence in the project. I am simply trying to obtain the inters…

Hmmm… can you share the lines as you currently have them? Have a few ideas with this larger goal in mind, but they may not pan out. I’m not using my work CPU today (holiday), so no Revit or Dynamo playtime on stuff like this for at least 24 hours, but someone else might be able to help out and prov…

Thanks @jacob.small … and I appreciate you all looking and helping me with this. I totally understand and here are attached the Revit + Dynamo Graph attempts. ForumSample.rvt (352 KB) Polygon2JacobSmallMethod.dyn (13.7 KB) Polygon2VikramMethod.dyn (9.8 KB)
