When I use the unroll command in Rhino, the surface seems to unroll normally.
However, when I use the same code in a GhPython, things go haywire. Sometimes the development doesn’t even come out and it gives the error “Not set to instance of an object”.
Every time I tried this, it worked flawlessly in Rhino. Whenever I tried the same in grasshopper, it didn’t seem to work. Is this a bug, or am I doing something wrong?

The red is the unroll that GH did and the blue is the one I got with rhino.
