In this video, we create stepped surfaces using NURBS surfaces and IsoCurves. While focusing on parameterization, we also touch upon the relevant Data Tree management tools and revisit Custom Preview, the Gradient, and the Color Wheel. Enjoy! This video is an introductory tutorial for beginners in Grasshopper3D and Rhinoceros.

In this video, we look into ways of converting Rhino's Subdivision Surfaces (SubD) to NURBS Surfaces in Grasshopper3D. We touch upon some SubD modeling tools, cover the SubD Face Packing, and discuss the Default conversion options.
