Can someone please go over how to create a nurb surface, and patch surface. I don't understand this.

I will do some quick tutorials for modeling with NURBS surfaces soon.
You can create surfaces with Loft tool and Patch tool. You can extrude them. Slice with Add Point tool.
Actually all edit tools works with NURBS surfaces.
And most of Primitive tools have an option to create polygons or nurbs.

Current tool-set is still quite limited.
But there will be more additions during LWCAD 2018 cycle.

Here is the old tutorial.
