Structures from Point Group - Only one structure is being created instead of all eleven in group

Thank you in advance for any assistance. I’m new to Dynamo for Civil 3D. I’m trying to create a script that will create pipe network structures from a point group of catch basins. The point group contains eleven points but only one structure is being created. I’ve attached an image of my dynamo script.

Hi @dana.riceN32EY you should familiarize with the concept of Lacing to understand why you had a different result from what you expected.It is plenty of articles in the general Dynamo session of the forum.

Thank you
