Smooth T Spline/Weaverbird object from GH Hex surface?

Hi All,

I've been through the process by the amazing Rodrigo on how to create http://designplaygrounds.com/projects/responsive-morphologies-gh3d/.

I'm now at the stage where I have the hexagonal surface and can adjust the percentage cells that have either one aperture or another. I can bake out the surface into a seemingly single surface in Rhino.

My question is, how do I create the smooth, 3D T Splines mesh as created by so many others, in the example by Rodrigo, but also elsewhere on the forum (http://www.grasshopper3d.com/photo/hexa-mesh?xg_source=activity)?

Thank you all for your help in this, and if you require me sending any more information about my stage-progress, just let me know and I'll post it here.

Thanks again,

Liam
