Hello I followed the diagrid tutorial found here: http://digitoolbox.wordpress.com/2008/08/14/how-to-create-a-differentiated-component-in-grasshopper/.
I've been trying to create a box section extrusion with the generated lines from the diagrid. The piping method is nice and clean but I want to manipulate the structure with a rectangular cross-section. I tried offsetting the curves, lofting, and then extruding them but the directions were not normal to the surface. Any thoughts on how to go about this? Thanks.
