Thanks for the quick response.
No, I'm referring to the command "trimblein"used for scaling a drawing to 1/12th and exported as dxf for use as a background in the handheld Trimble nomad unit
I'm not aware that there was ever a TRIMBLEIN command. A listing of all the CADmep commands can be found here...

If you had a TRIMBLEIN command, it was likely from another program (something TSI/ASTI sold) or a Lisp routine, etc.
Darren,
The command is an Autocad command in 2016 Cad-Mep
TRIMBLEIN is not an AutoCAD 2016 command. It's not a CADmep 2016 command either.
As I said earlier, if that works in your install of 2016, it's another software package or macro or lisp routine or alias or something that someone else created.
I'd check in the "draw..." folder listed in your screen cap because CADmep out of the box does not have any folders with that name under "C:\Program Files\Autodesk\Fabrication 2016\CADmep\"
