T-splines to GH

Hi everyone, am still pretty new to GH and it will be great if someone can help me solve this.

I am trying to build a UV structure from a surface. I have drawn the surface and converted to T-Spline so as to get that extra smoothness (pls see first image), however the GH definition I have drawn do not go on the surface even after setting it. it only shows lines on the XandY axis.

Secondly if you look at my GH definition I get an error between EXPLODED and ITEM component not sure what am doing wrong.

The second image shows what am trying to achieve, any help will be greatly appreciated.

Thanks

Red arrows: right click->reparametrize

Blue arrow: I imagine you will need to play with the i numbers here as well

Thanks Ching, the reparametrize worked but still stuck with the Explode and Item connection. Any more ideas?

Thanks

Can you show us what's the V of the Explode outputting with a big yellow panel thing?

Send me the file and I will fix it

Your model is way too far from 0,0,0 so I moved it closer.

Also your surface is a trimmed surface which makes it require some more operations than the example you got.

Also, the fins do not have thickness if you follow that example. I'm sure they didn't publish everything on that page or something.

Thanks Ching,

I just tried opening the GH definition but got this error, could it be my version of GH?

Thanks

Most likely because I can open it fine with the latest version.

Ok, I'll try and upgrade my GH but in the mean time what did you add or remove from the definition?

Thanks for your help man..

Genius, I will try and draw this and see how it goes.

Thanks.
