Thank you for kind explanation.
I understood the Kotatsu, its so simple.
Actually, this is my first time I post here.
I’ll be careful to name title and what to make.
That is to say, maybe I should use NURBS when more exact models with accurate dimensions is required; for example, designing a piece of furniture, and it’s more suited to use Polygons when complex visualization with fabric simulations for rendering is required, is it ok?
Mr.Daniel’s textile draping is so interested.
I didn’t know such a way to use Grasshopper and Kangaroo, I’ll challenge it.
