Hi,
I have some problems to import parameters values into Revit.
The dynamo script reads my excel file without problem, the list is ok.
But then the value writtent in Revit are completely wrong.
This are the values inserted in Revit (7237.7860 m³/h and 7339.7266m³/h) but in my Excel file the values are 63 and 64.
How am I supposed to fix that?
Thanks.
@erfajo so in Revit, air flows are in ft³/hr?
Edit:
Just converted the air flows in Excel from m³/h to ft³/h.
Dynamo still has the correct value but again, Revit’s are completly wrong.
Have you tried the MEPover node “SetParameterAsProjectUnits”? Because it sounds like a conversion issue between Revit and Dynamo, but I could be mistaken.
Edit: From a quick Google search it seems that the internal unit for air flow is ft³/min (CFM), does that seem more reasonable?
@erfajo is right here.
I don’t know why exactly it happens but I’ve just checked how it changed and added a calculation within Dynamo and though it’s not ideal it does work.
SetParameterAsProjectUnits works ok.
This was indeed a unit problem 
I wonder if I am going to convert in Excel or Dynamo or use SetParameterAsProjectUnits
Thanks.
Just so you know @erfajo Revit was built in the USA a decade ago and the very first version(s) had no metric in it, it was all imperial 
Rebuilding a software to go unitless is… a HUGE task:)
Why are the US still using imperial measure is … another debate. But in the mean time, the US changing the units of measurements wont solve the issue
So we go with simple conversion
I think that One day they wil adapt and need to adapt even the US
they are almost alone
but its harder for a large country to adapt then a little country
