Improving /preparing a Surface for Grasshopper use

Rhino Rhino for Windows

Hi everyone, I have a collection of tileable pattern from CAD & Sketchup but can anyone please point me to right direction on:

  1. How to create a clean one in Rhino? It always produces triangulated surface.
  2. How can I hide the seam line (I don’t want this seam edges to be visible when I used copy array in Grasshopper)

Please see attached file. Thanks!

Hello - there is one curve in there which has a self-intersection preventing PlanarSrf from working - if you clean that up, PlanarSrf should be what you need, I guess.

Hi Pascal, Thanks! how where you able to spot that? Is there a command in Rhino like find gaps/knots or something similar?

Hello - just boring old ‘binary’ testing - it looked wrong and I get the error message with all the curves, so try half at a time and half of those - it’s pretty fast to work down to a manageable few curves.

Thanks a lot, the PlanarSrf worked well. Now I have a surface. For #2 question, what’s your suggestion? any possibility of hiding these seam lines during array? Thanks

I would just delete those lines from the original curves and then create the array that you need. After that, you can surface the curves.

I see, thanks! Does it also implies that the common/recommended process in grasshopper is to first establish curves (then array or scale or move…whatever) then finally the surface creation is the last/ among the last in procedure? Thanks!

I’d say that the only recommended process in Grasshopper is to keep things as simple as possible. (-:

That is kind of implied by the need of parametric design, if you start from the surface you don’t really have control over it ;).
