When using AutoCAD MEP or AutoCAD Architecture it is always important to open a version that preloads the correct profile. For example, when AutoCAD MEP is installed it automatically loads an imperial and metric profile with 2 preset desktop icons.
The challenge for a user is to make sure they have the correct version open when working on a DWG. If you are working on an imperial dwg you should open the imperial version of MEP.
To help users understand which version (current profile) is currently open without resorting to checking the profile in the OPTIONS, the following steps can be used to display the version in the status bar like this:
You will need to modify the acad2012doc.lsp file in AutoCAD MEP. Look for a similar .lsp file in AutoCAD and AutoCAD Architecture

3. Add this variable as the last line item: (setvar "modemacro" (getvar "cprofile"))
4. Save the file
