Dimension Settings Dialog Box (AutoCAD Mechanical Toolset)

Use this dialog box to set preferences for Power Dimension commands for the current standard.

Dimension style
	Base dimension style Sets the dimension style to be used as the base dimension style. All the dimension types are based on the dimension style or a variation (a sub-style).
	Edit Displays the Dimension Styles dialog box, enabling you to create, modify, and assign dimension styles.
	Force power dimensions to use this dimension style Prevents the dimension style from being overridden with the DIMSTYLE command.
Default representations
	Chamfer Displays the Chamfer Representation dialog box, enabling you to select the default chamfer dimension representation from a predefined list of representations.
	Radius Displays the Radius Representation dialog box, enabling you to select the default locations for dimension line, dimension text, and arrowhead for radius.
	Diameter Displays the Diameter Representation dialog box, enabling you to select the default locations for dimension line, dimension text, and arrowhead for diameter.
Dimension Text
	Ignore AutoCAD scale factor for linear dimension measurements Makes Power Dimensioning ignore the DIMLFAC system variable and other settings that control the linear scale. AutoCAD Mechanical toolset uses several scaling mechanisms such as scale areas, detail views, and annotation views, that are not available in AutoCAD. Power dimensioning recognizes the scales and automatically compensates for them. If you choose to honor AutoCAD scale factors and use different scales in different places in a drawing, AutoCAD Mechanical toolset's scaling mechanisms may not reflect the correct dimension value. Note: This setting is not available for Inventor linked drawings.
	Predefined Text Displays the Predefined Text dialog box, which enables you to create predefined dimension text templates for Power Dimensioning commands at draw time.
Fits and Tolerances
	Fits Displays the Fits Representation dialog box, which enables you to set the default fit representation. It also provides access to the System Editor, which enables you to modify the Windows registry settings that define the existing fit representations as well as create new ones.
	Tolerances Displays the Tolerance Representation dialog box, which enables you to set the default tolerance method. It also provides access to the System Editor, which enables you to modify the Windows registry settings that define the existing tolerance methods as well as create new ones.
	When a fits list requires updates Configures how fits lists rebuild. You can choose to update fits lists schematically, have the system prompt you, or update fits lists on demand by selecting the manual option.
Placement Options
	Display visual aids when creating dimensions Displays an icon on the crosshairs when a dimension is created, indicating the type of dimension being created.
	In chain dimensions, replace arrows with points for lengths less than Defines the distance at which arrowheads are replaced with points in chain dimensions.
	Use distance snaps for placement Turns on distance snaps, which cause dimensions to snap into place as you move the dimension line in the drawing area.
	Snaps value Sets the distance from the snap position to the object being dimensioned.
Display dimension text editor Sets how often the dimension text editor appears during a command session.
Show text override prompt Enables the display of the text override prompt enabling you to modify the dimension text on the command line during the dimensioning process. By default, this check box is cleared.
Restore defaults Resets all settings to the factory settings for the current standard. If the current standard is a custom standard, the settings default to the factory settings of the standard it is derived from.
