Mmm I don’t know how you are measuring interest but I they think many people make this type of models in Rhino and would find your plug-in really useful… I just feel it needs some proper broadcasting channels to reach them. Most users don’t check this forum and much less this specific thread.
Also I feel that if you could somehow combine this with Grasshopper that would also be extremely powerful and people who use that tool would find it even more interesting.
