Issue with Subdividing Surface on Grasshopper(Isotrim)


I have constructed a surface out of a closed nurbs curve and the patch component however, when I try to divide the domain and subdivide the surface with isotrim the isotrim surface is not the same shape as the desired patch surface.

I have attached the grasshopper file with internalized data below, any help would be very much appreciated.

A patch surface is a trimmed surface (Brep). Iso’s use the underlying surface of that trimmed surface. That is just something you need to understand about Nurbs models.

Oh I see.
Then do you have any advice for how I can fix this issue(as in, turn the closed nurbs curve into a surface which I can then subdivide with isotrim).
