DIMSCALE resets to 0

[tgross.197084]

One of my users came to me with a weird behavior on her drawing (while working in AutoCAD2010). It seems to be drawing-specific. After an annotation scale has been set in a drawing, it doesn't seem possible to set DIMSCALE properly.

All of the dimension styles, text styles, tables styles, and multileader styles in the drawing are non-annotative. You can set DIMSCALE to, ex. 48, but then it changes back immediately when you run a dimension command (and the Fit value for the dimension object created is 1).

Command: dimanno

DIMANNO = 0 (read only)
Command: cannoscale

Enter new value for CANNOSCALE, or . for none <"1:1">: ..

Cannot set CANNOSCALE to that value.
*Invalid*

Command: dimscale

Enter new value for DIMSCALE <0'-0">: 48

Command: dimscale

Enter new value for DIMSCALE <4'-0">:

Command:
Command:
Command: _dimlinear
Specify first extension line origin or <select object>:
Specify second extension line origin:
Specify dimension line location or
[Mtext/Text/Angle/Horizontal/Vertical/Rotated]:
Dimension text = 10'-8"
Command: dimscale

Enter new value for DIMSCALE <0'-0">: *Cancel*

The reason this happened is that the user was drawing in a non-annotative drawing and copied in annotative dimensions from another file. (We work for public clients who are picky about their standards, so the obvious answer of "use annotative annotations" can't help me here).

We have a few installations of AutoCAD MEP floating around, so I checked to make sure that AECDWGSETUP was set so as to not automatically create DIMSCALE overrides.

Any suggestions?

Why don't you post the drawing? You can post it without any objects in it, if that is a concern.
