DIMSCALE
Controls the scale factor for variables affecting dimensioning size, distance, and offset.
If set to 0 and annotative scaling is turned on, dimensions located in a layout viewport are scaled according to the relationship between the viewport scale in model space and the layout viewport scale in paper space. If set to 0 and annotative scaling is turned off, dimensions located in a layout viewport are scaled according to the layout viewport scale. When DIMANNO is set to 1 (dimension style is annotative), this system variable is set to 0.
