Dimension VariablesThe ollowing list shows the AutoCAD dimension variables that can be

stored within a drawing or template fle. The value o each o these variables iswritten into the fle when the drawing is saved, so the next time the drawingis opened, the values remain the same. Although the easiest way to set thesevariables is to use the Dimension Style Manager, the values or most o thevariables can also be set by entering the variable name or by using the SETVARtool. Some variable values are derived by AutoCAD rom the current condition

o the drawing or the drawing environment, and cannot be set directly. Theseare reerred to as read-only variables.

The ollowing list provides a brie description o the system variable andthe deault setting when no specifc drawing is reerenced. The symbol ( )indicates that the variable is read-only.

DIMANNO Tells i the dimension style is annotative.DIMAPOST Preix/suix or alternate units dimensions.

DIMARCSYM 0 Displays arc symbols in arc length dimensions.

DIMASSOC Controls associative dimensioning.

DIMASZ 0.800 Dimension line and arrowhead size.

DIMATFIT 3 Controls placement o text and arrowheads when there is insu-icient space between the extension lines.
