Can we have a ToNURBs with options Grasshopper component please?

Rhino SubD
1

Hi Guys,

My junior designer ran into an issue today.

He has a SubD object which he is pulling into GH to script up a number of Boolean operations.

In the course of GH doing the booleans it converts the SubD into a Brep, however the default on this conversion unpacks all the faces into separate surfaces.

If you convert the SubD using the ToNURBs you have the option to pack faces.

It is less than ideal in the work flow to have to manually do the conversion to get the packed version.

Attached is an example of what we are seeing.

I checked the API and it appears the options are not exposed yet, so we couldn’t ‘roll our own’ in C# either.

Can you please add a ToNURBs with options into Grasshopper for us? PLEASE?

Opps - I may have been mistaken about the options being available in the API
