Hi everyone,
I’m beginner with Dynamo and I would like to understand this error. I would like to build walls with listing topographic points for a semi automatic modeling with Dynamo but at this stage of the process I dont understand, even when I put curves.
If anyone has the solution please ! thanks 
Hello @Evolve and welcome to the forum, maybe that one expect curves and not polycurves, try with a geometry explode node or polycurves curves node before feed in
are your sure the curves is on plane ?, try pull the curves on plane node with xy plane…maybe;) not at dyn in the moment
okay I would try this ! thanks
yeah or pull them to levels plane not sure we have ootb nodes for that, but guess clockwork have a node for that,
