Projection

Hi!
I do not understand why only one line will projected to the surface? Should an imported surface in dynamo prepared to a geometry first?

Thank you!

Because its most likely a list of surfaces with one item. Change the lacing of Surface.ProjectInputOnTo to Longest and it should work.
