Hi got different poly curves and would want to create a surface within those poly curves. I’m stuck here and cannot go froward. Any pointers. Here are the poly curves generated from Dynamo using the points.

Here is the script for it.

Hi Rooney,

Did you try running the list of polycurves through a Surface.ByLoft node?

@Rooney_Wayne You seem to be exploding the polycurves (by using Polycurve.Curves) into their component curves and then trying to loft  
Pass the Polycurves directly. It should work.
