I am starting to test out the mechanical systems tools within Revit, and whenever I try to create an exhaust system for my generator, I get this error.
"Mechanical Exhaust Air 1: Flow direction mismatch. Impossible to calculate flow. Check flow direction on all equipment in this system."
On my connectors I have tried numerous combinations of flow directions, but I continue to get the same result. Anyone know how or why you get this error?
