Hello. I have the following issue: I need to divide each closed curve, into several smaller closed curves, along existing division lines. Is there any way to do this with less labor? [Divide_curve]

I think you could make a surface out of your initial closed curve, split it, and retrieve the edges of each slice

Curve.CreateBooleanRegions might work for you. I don’t know if it’s implemented in native Grasshopper components yet, but one can implement it a scripting component if not: [image] Divide Closed Curve into Cells with Python or Efficient Method Grasshopper Ah that’s a real…

Thank you. I downloaded the grass-file, but I get an error when opening the python script: ‘type’ object has no attribute ‘CreateBooleanRegions’. Maybe the problem is in the Rhino version? I have 6. [image]

That was my first thought, but I have a lot of branches and elements, so this approach takes a lot of time and I’d like to do without building surfaces so as not to reduce the speed of the script.

Can I get any solution in Rhino6?
