Create Surface from Non Planar Curve

Hello Rhino forum,

I’m a newbie working my way through the Rhino Level 1 Training Guide.

I want to create a surface from a non-planar curve as shown below, with no curve in the x direction. Which commond do I have to use? I tried “Patch” but that creates a surface with a bend in the x direction.

Perhaps someone will take the time to answer my very basic question, thanks!

please upload your curve here.

Hi Alex, It is basically a cylinder. The radius is around 6.25. You could extrude a cylinder then use the curves you have to split that cylinder. That is one way to get there. —Mark

i simplified the curve before splitting but it should work without either.

I used @encephalon’s suggestion, which seemed the most straight forward to me.

I will also try to build the surface using @11165 and @markintheozarks suggestion, seems I can learn something here.

Thanks, guys!

I strongly recommend using extrusion+split on developable surface like this.
