Thank you for the good work so far on SubD modeling and features.
For the marine industry, there are a few vessel hull types that ask for SubD modeling and I did a test. It all looks very promising.
The attached hull is something that can be used for testing SubD: 11 Discourse SubD-ShipHull.3dm (4.9 MB)
Furthermore there’s a little Grasshopper script to make a lines plan and being able to do curvature graph analysis: SubD-Grasshopper.gh (24.3 KB)
What I found out after generating a Nurbs object out of SubD, is that every panel is converted to a Nurbs patch. What I liked about T-Splines was that it was possible to convert areas to a single Nurbs piece as long as the panels had four sides. In the case of this hull that could be a big part of the hull shape. Is that something feasible?
What I miss right now for fairing purposes is:
