Using 2D projection to build surface based geometry in Grasshopper3D.
I've been using Grasshopper3D for commercial work long enough to develop some practical habits. I want to share one of them. Sometimes questions come with diligent but slightly overcomplicated definitions as examples - asking how to build a pattern or a truss. This usually involves geometry that is based on one or more vector surfaces. I wanted to share some less than obvious information that might help some people (beginners) with their projects.
