Paneling Tools - Custom pattern failing


Pretty new to Rhino. I’m trying to apply a kerfing pattern to a doubly curved surface. I’m using ptPanelGridCustom to apply the below pattern.

It works fine on a flat surface.

When I apply it to my curved surface, part of the pattern works fine, but a portion of the interlocking part breaks, resulting in stray lines everywhere.

I initially started with 4 open curves.

I had the same issue so tried changing the geometry to 2 closed curves, but that didn’t fix the problem.

Any insight as to where I’m going wrong?

Thanks in advance.

This unit pattern has overlapping parts, which is predictable when distributed over a flat grid. Let me spend more time to see if you can reconfigure the pattern to have more control over the overlap, and distribute more predictably. I’ll get back to you soon.

I redid your example with new module that is more modular (and has no thickness for simplicity), but you should get the idea of a workflow that might work for you.

Amazing! Thank you Rajaa so much for your help and solution to this issue. I’ve really enjoyed your tutorials on Rhino and Grasshopper.
