I’ve got a similar request, to determine if a second parameter could be “flowed” through the system…
In a drainage system, pipe cannot reduce size in the direction of flow (code requirement). So, I’m trying to come up with a method that will check the sizes of all upstream pipes to make sure any particular pipe segment isn’t smaller than any segment upstream (or prior) to it.
Is there a way to pass a parameter through the piping system that tracks what the maximum upstream pipe size is it might there be some other recommendations to accomplish what I’m trying to do?
I’ve cross posted here:
