Hello, I am building a triangular lattice structure between two surfaces. I have come up with a lattice structure that I am happy with that works between two simple loft test surfaces, but when I apply the same definition to the final surfaces I want to use it for I can’t get it work in the same or…

Here is a screenshot of the test (first) definition if helpful: [image] Screenshot of the final (second) definition: [image]

It seems the issue is the way the surfaces are made from SubDs and the way they are ordered. On a very simple SubD plane converted to nurbs I get a somewhat symmetrical (still incorrect / not controllable) result: [image]

[image] rayhoracek: something simple Doing an AEC truss using a double curvature Nurbs Surface (or 2) OR a blob type of Mesh using Vertices Normals (steady amplitude or variable: say related with attractor Pts/Curves/Objects or some other way like s Sin/Cos global distortion etc etc) is the …

Thanks for the help and advice. I should have been more clear but this is for an elbow brace so luckily I don’t have to worry about things like BIM and outputting lists. The final strut collection will be put through Dendro to connect the thickened strut volumes all together into a single mesh for 3…

[image] Ray: same as normal nurbs surfaces with this definition. Did you ever figure out a good method?

No, unfortunately - another GH expert told me it’s better to build the surfaces as lofts from curves instead so you can control the order so I did that and it worked.
