hi all,
Is there a way to take SubDs objects in GH and covert them to nurbs? I do not see a _ToNurbs component right now. It looks like the SubD ControlPolygon made it into last week’s build, but not _ToNurbs yet. Correct?
Thx,
G
oooh, that makes sense! in a weird way. thanks 
Hi all,
We are working on some tools that require Subd-to-Nurbs conversion in GH for certain operations. And we a way to _ToNurbs in GH that give us packed surfaces.
The solution @Mahdiyar provided last year does not give us the option to create output that’s a single surface.
See below:
Can you please add the _ToNurbs component to Grasshopper?
Also why so many modeling tools are missing in GH?
for example in SubD alone, this is what’s available in GH:
and this is what’s available in Rhino:
Thanks,
Gustavo
Hi @gustojunk,
The capability of the ToNURBS command is available in RhinoCommon using SubD.ToBrep. You should be able to create a C# component that calls this.
test.gh (46.3 KB)
Let me know if you need help with this.

thanks @dale, this will do it! I still do not understand why so many basic geometry tools are missing as Grasshopper Components. It’s like if you guys expect only programmers to be able to use GH beyond the basics?
Sometimes I want to try a few concepts to then pass to our team, so they can write cleanly and optimized, but missing so many tools really kills a lot of exploration IMO. Just me?

I’m sure @DavidRutten is more than happy to add new components based on demand. But what Grasshopper is missing is often achievable by calling RhinoCommon directly using a scripting component like C#.

Meanwhile, you can find some of these basic subD commands in IAC plug-in:
SubD is also WIP far as I know. The options are changing often with service releases.
