[quote user="Oto"]Text fields doesn't honor MS_MEASURE_AREA_UNIT2 variable so label "sq. m" is shown as "m2" [/quote]
If that's not a programming question, then please ask it in the MicroStation Forum.
What you're referring to is the unit decorator. The choice is, for example, Sq meters or m2 (when master units are metres).
Another setting relevant to all measurements is accuracy, which determines how many digits appear after the decimal separater (e.g. 1.23 or 1.2345).
