Actually same problem for my side,

For example;

 - Round transformation; you can see properties tab; Loss method, loss method settings.

   If you select coefficent from ASHRAE then revit will automatically select data ( from ashrae table )

This point, we have a big problem !

There are a lot of fittings that we may use our projects. For example, different Tee's, rect to round transformer, shoe branch, reducers, wye etc.

Problem 1 - If you want to create a new family, how can i input loss coefficeint data !!!

Problem 2 - If you use revit default fittings for tee. Revit did not give a permission change loss method setings. Report show 0 for tee. Of course, i want to input data for manually however i could not find yet.

Help me please !!!

Hi, try to change the decimal separator of your computer from "," to "."

Go to the settings of your computer into "region" and change it.

Reboot revit and launch the calculations again, it should work

It would be great if Revit could the decimals configuration (".", ",") from our Revit Project units
