thanks @gonzalocasas.  
Thanks for the NURBS link, that didn’t come up in the previous messages. There are two threads that I posted, this one and also another about [Rhino from\_geometry()](https://forum.compas-framework.org/t/compas-rhino-from-geometry-implementation/460).

Above in [this thread](https://forum.compas-framework.org/t/grasshopper-workflow-which-libraries-modules-to-use/456/8), there are some comments about NURBS actually, I found that when converting from [Rhino to COMPAS, there are only three lined types](https://github.com/compas-dev/compas/blob/main/src/compas_rhino/geometry/curve.py#L20) supported which don’t capture the richness of a NURBS curve. The NURBS curve isn’t implemented yet, as you say.

Maybe I need to review the NURBS package as you mention in the meantime?  
I notice that the COMPAS NURBS you sent is actually not integrated to the COMPAS Docs, that’s also why myself and others didn’t see it. It’s in the Gramazio Kohler repositories.
