FamilyInstance.ByCurve returning Null values

Revit
1

Hi, I’m trying to automate the creation of beam encasements around structural framing in a linked model.

I’ve got a line-based generic model family, with varying types based on the beam, and have used the Bimorph package to retrieve the location of the beams. However, when I try to use the FamilyInstance.ByCurve node from Clockwork, it’s returning null results.

I’ve tried playing with the lacing and levels, but can’t seem to get it to behave. Any suggestions?

Ignore everything around lists, and even your graph. Save it and start a new Dynamo graph in a new Revit file with one of your family types loaded in it. Can you make this work for one curve with one family type? If not then you can zero in on the root cause having nothing to do with your data structure and move o to other possible issues.
