Assemble Model gone red

Support position extracted from a point coordinate list for lines (converted to beams) is not accepted by Assemble Model (although the beams are). These points show up green at the right places in the Rhino window. How come? (49.7 KB)

Hi @ingemar, make sure to flatten the Elements input (or namely every input) in the Assemble Model component as Karamba3D maintains the data structure of grasshopper.

Thanks again Matthew, it worked out fine by flattening!
