Truss Design from planer curves

Hi all, I’m attempting to create a truss system out of an uneven poly surface in grasshopper. When I create the ‘Set one surface’ , ‘segments’ , ‘surface’ , etc… grasshopper then creates a full border around the entire surface and builds in that space. It ignores the boundary of the surface in the image I posted here. Is there any way around this?


Try this. The 2x move component are just for better visualisation. The whole thing was to extrude the trimmed surface and use “Trim with Breps”, to get rid of the curves outside the boundary.
For the future, better upload your specific file, so nobody has to recreate something. (16.4 KB)
