This app helps MEP elements (duct, pipe, cable tray, and conduit) to modify level offset up or down.

By splitting the elements and input offset/angle value, the app redraws elements automatically.

The app works with any language version of Autodesk® Revit®, but the command is in English.

It is useful for Revit HVAC, piping, and electrical modeling.

It saves modeling time, improves model quality.
