I am attempting to set the value of the ‘Specified Exhaust Airflow’ on a Space. The default value is 0.00 CFM. I have a list of spaces and a list of CFM values of equal length that I am assigning. If I check the output from the spaces coming out of the SetParameterByName node in Dynamo using GetParameterValueByName it appears to be working, but in Revit nothing appears to be changing. Any ideas as to why this may be?
