Hey,
not yet. This is because I currently don’t use Rhino (or any other CAD) at work. Let me also claim that I’m really fluent with the RhinoCommon and Grasshopper API. And since I’m also professionally developing software, I don’t think it will give me much benefit for using the API. However, as soon as I would need to look for a particular algorithm (e.g. Kd-Tree, Convex Hull etc.) or if I’m looking for an optimization, then I believe it could be a great help or at least a time-saver.
