Hi. I understand that Revit will not run a fixture unit count if any piece of piping is open, ie not connected to anything. How have people gotten around this problem with vent piping, and piping entering and leaving the building?
Solved! Go to Solution.
Its my experience that if you change the SAN elbow into a tee then contiue drawing with Vent 'system' pipe, the fixture count is lost, even if the vent pipe is capped.
Has anybody found a solution or workaround to this?
The outside connection can remain open, as long as the rest of the system has no openings.
