“Could not find node at … where support is attached” error

Thanks for the suggestion. I tried snapping the support points to the Point output of the LineToBeam component exactly as you described and then used those points as input for Support Pos/Ind. Unfortunately, the issue persists and Assemble Model still throws the same error:

“Could not find node at (…) where support is attached.”

I am attaching a screenshot of the script showing how the support points are generated and connected. It seems that even when using the LineToBeam Point output, Karamba still fails to associate some supports with valid nodes in this highly connected parametric structure.
