Is there a reason the CP Tier is parent to the System Tier? Seems to me that it should be the other way around. Circuits are typically smaller than systems, and plastic parts of a system will not have a circuit.
They are in different tier groups, so System is 1 in its tier group and CP is 1 in its.
That's what I would think, but my system and pressure subnets are not generating, whereas I had no trouble getting them built with UPDM 2018, and I thought it may be due to the CP tier. I'm clearing out the topology right now, and when I re-enable it I'll see if I can give you some better details as to what I'm seeing.
Aha! My associations failed to import. I tried exporting them, and nothing came out.
Well, this is weird. With UPDM 2018 my associations came in slick as snot. Now they're coming in, but meaningless. Just a heads up, I need to reanalyze my scripts.
