generative modeling for Rhino
I too would like to use the "Extrude curve Normal to surface" as in Rhino for GH. Is there any other discussion on this topic or can anyone else please help?
I need to construct vertical and horizontal support webs (normal to the surface, not parrallel to each other) of a constant width.
Similar to the attached rhino doc.
That looks great! Many thanks for your help. I'm new to GH and will need time to understand each part. I am interested where you got the curve data in the curve paramater at your start?
I previously started with the example by Zubin (p153 fabrication) attached, as it is handy to have sliders for the curves but your method appears simpler.
The way you have extruded the curve from the surface works along the normals, which is probably good for Des; But, the way you've projected the original curve to the original surface doesn't quite follow the surface normals. Check it with Rhino's "Pull Curve to Surface" command.
Admittedly, Juan's original question in the post isn't clear to me. But inferring from the post's title, I think an accurate normal projection is what was originally asked for. The attached definition will provide an accurate projection of a curve to a surface via the surface's normals.
From there one could use various methods to extrude or loft along the surface normals.
