Revit MEP 2012 Round duct fittings coefficients METRIC

Hello!

 

I am having a problem with a pressure drop calculation in Revit for round duct. When working with Imperial template loss coefficients are defined accordingly and all works fine, but when you switch to Metric template, it looks like Revit can't read any information about the diameter of the pipe and can't define the coefficient. If you check the tbl file for lets say CD3-11 or other round duct fitting, you might notice that the information provided in inches and (mm). I tried different scenarios like editing .tbl files and ashrae.xml, but though still can't get it working. I believe that the issue is caused by project units.

 

Is there anyone with similiar problem ? Is there maybe any fix for it ?

Hello!

 

I have the same problem. Did anyone find some solution? I think the problem is with all tbl files where are used metric dimensions.
