I have a lisp routine for Autodesk 2012 CADMech. This lisp would allow you to select all the hangers within your drawing and input the desired "Z" elevation of the end of the ATR in inches. It worked on all hangers: Clevis, Roller, Trapeze (Profiled Bearer), etc.. I can't get it to work in 2017 Autodesk Fabrication/Building Data. Does anybody have a script that performs the same type of function and works in 2017 Autodesk Fabrication? Attached old lisp file.
