Surface to model

Hi, I am wondering how can this surface be modelled in Grasshopper3d? I have tried different option like assuming Hyperbolic surface but the results do not match with what I want. If I can only know the surface I can do the truss and etc.

Do you need to create this surface in grasshopper? Why not create in Rhino and do the truss work in Grasshopper?

Luchbox plugin has a different tessellation tool that fits what you want…

Hi Kim, long time no see. My problem is mainly with surface. How can I model the surface in GH.

I reckon you need to transfer the manual workflow you’d follow in Rhino. Gh is no different. Start from points, then curves, then surface?
