Hi, Is there a way in python to join together a bunch of LINEs that have endpoints touching each other, to form either a ClosedPolyline, or better still a ClosedPolyCurve? (Without having to ‘manually’ iterate through all lines, and search at their endpoints) Note that this need be done in Batch a…

Hi @Rhino131 Take a look at CurveBoolean with DeleteInput=All, CombineRegions=No and then select the AllRegions option. In the second step, just press Enter for all available regions - it can be easily be macro’ed if you want to automate it. HTH, Jakob

Hi Jakob, Thanks for this pointer. I will look, but running this in GUI is not an option I will see if there is a RunCommand option/variation that does not require operator input. Thanks and regards, Zoltan

Hi @Rhino131 Sorry - didn’t notice the “Scripting” category :clown_face: My bad! Hopefully you’ll figure something out or get help from one of the begger brains! :slight_smile: -Jakob

MeshFromLines - now that sounds like the real deal. Many thanks for the pointer/nudge.

No worries. If you’re dealing with many lines, this code will be more performant for extracting face loops: [image] Face Boundaries faster Scripting If you translate this GHPython code to C#, I bet that’ll get you close to native performance: [2023-08-25 14_…
