Cant create multiple family instances with list


I’m trying to place 4 family instances, I’ve passed the FamilyInstance.ByFace node a list of 4 points, but it only creates one instance:

The image below is the Revit 3D view, the blue spots are the 4 points, the circle is the family instance (generic model - a cylinder), you can see only the first point has a circle around it:


What gives?

Attached are the files.
Check placement routine 01.dyn (7.8 KB)
Place FI.rvt (2.1 MB)


Lacing needs to be on longest or Revit will stop at the length of the shortest list - the single family name in this case.

Ahhh - Should have thought of that!

Thanks for your help!
