Flow Units export to Ifc not correct (revit 2020) #444

Open MMorsinkhof opened 2 years ago

MMorsinkhof commented 2 years ago

If I export a Revit MEP model to Ifc the exporter(or revit) doesn't use the correct units for the flow parameter. It has to be L/s but in Ifc it becomes ft3/s. This is not correct, this unit isn't even available in Revit (by choosing by the project units). I tested with base quantities and by a custom pset, both won't let me export the correct units. I also tested it with the unit volumetricFlowRate, also this values is in Ifc in ft/3.
