Very interesting. I have been playing with tunnels but not having success. Love to know a secret or two of this definition.

Thanks. That is the missing link I needed (I think at least).

Hi Damon, UV domains are indeed utterly meaningless. When we create a new surface we of course need to come up with some Domains, so usually we'll pick something that corresponds roughly to the dimensions of the surface, or the number of nurbs…

How is 'u' and 'v' determined for a surface?

I am trying to use the SubSrf(isotrim) module. It wants input of a range for u and v. I can input those and get a portion of the surface, but what I don't know is how to determine the region I want. The domain numbers do not seem to correspond to anything I can think of. Not to the number of control points for the NURBS surface. The surface is a direct input, so clearly GH has a default method of setting the uv grid for a surface.I even did a trial where I divided the original surface into a…See More

Your problem is that the curves you're trying to loft each have a different path structure. Flatten the projected curve and you should be fine.

Thanks for the detailed explanation. That makes it clearer. I have attached the definition that is not lofting. Maybe the problem lies elsewhere than the curve difference. I did rewrite it based on Dirk's advice, and that version works, but…

First of all, periodic curves are all one curve span, were as non periodic curves may be made of pieces of other curves. The places where those curve pieces are joined result in kinks at those points. After that, the main feature of periodic curves…

OK. Thanks! Your first suggestion worked. Instead of projecting the curve, I projected the generative points and then made the new curve from the new points. So this problem is solved, but I still wonder about the larger issue. What exactly is the…

If you can post a simple version of the definition, we may be able to help. Could be an issue of how the curves are organized.

Lofting periodic and closed curves

Newbie to GH hoping someone has a simple answer to this problem.I have a definition where two 3D curves are generated from a set of points (as control points and as an interpolated curve). Then those curves are projected onto a flat plane below. I want to loft the flat curves to the 3d curves, but GH won't do it. It says it has NULL values. Is it because the original curve is periodic and the flattened curve is not?If I bake the curves, I can loft them in Rhino. Rhino also has a "MakePeriodic"…See More

I'd be happy to teach it to you and or your students. I held a workshop here at the office and got everyone in the office up to speed on it..
