@grahamlyon1977 - thanks for the clarification.
to address your question, "Why would we model it as duct/pipe? ":
This was was really more directed toward @dominikleuchter 's suggestion that "could probably use Flex Duct from HVAC as a template for the flex conduits"...
My inquiry in the prior thread seeing if this was truly the case... as I stated:
Does it provide you with the control and capability that you need from a geometry perspective, or does it leave anything to be desired? The reason I ask is that we've had requests for folks that have attempted to route PEX piping (like this and this), using flex piping, which is basically the same editor as Flex Duct... and they have struggled, as the functionality was designed for flexible connections at equipment more so than routing long distances, and on multiple planes.
