The Pressure Loss Report is a new function added in Revit MEP 2013. It can be used to create a report for duct and pipe pressure loss in mechanical and piping systems. See.
The Pressure Loss Report can be saved as HTML format by using the default template. Users can customize the report format by editing the xslt template file.
The template file can be found in the Program folder:
C:\Program Files\Autodesk\Revit 2013\Program\AddIns\MEPCalculation\PressureLossReport.xslt
You can add your HTML script to the template to create your own report style.
Note: Please back up the template file before editing it. An invalid template file may cause the Pressure Loss Report function to stop working.
This example shows how to add a Revit logo and some words to the top of the report.
