Deconstructing and Reconstructing NURBS Surfaces

Created by: wassimj

Problem statement

I am trying to learn how to deal with NURBS surfaces. I am not able to deconstruct and then reconstruct a NURBS surface using "Deconconstruct Surface" and then connecting that to "Build NURBS Surface". When I do so, I get various errors based on the options I choose. What am I doing wrong and what are the correct options and inputs to make it work?

Steps to reproduce

1. Create a NURBS Surface in the scene
2. Select it and link it to "Deconstruct Surface"
3. Link the outputs of "Deconstruct Surface" to the inputs of "Build NURBS Surface"

Expected result

A NURBS Surface output from the node "Build NURBS Surface"

Actual result

Error message

Sverchok version
