Richmond Surface III

[FordEarl]

Hello,

I am trying to recreate a Richmond Surface III in GH but I am having difficulty with the following:

1. creating a single surface when using surface from points
   this is what I am getting as result
   
   

this is what it should look like

2. I also want to keep the surface closed without gaps or overlaps when adjusting the sliders for the steps in the range component, including the v_step slider (v values) and the variable N slider.

Any help would be appreciated.

I know nothing about a ‘Richmond Surface’ but came up with this white group that seems to work well, with no other changes:

Graft your A (U parameter) input for the Cross Reference, then interpolate and close-loft the points at the end?

Thank you very much to you both!
Both options work great!
