Dimension Properties

Controls the format of dimensions. You can set the properties for all dimensions, or for just a single dimension. See See Object Properties.

Text

There is no Text page in dimension Properties, but parameters can be set in the Selection Info palette. For details on Text parameters.

...

Controls the shape of dimension arrows and the position of text relative to the dimension line.
  

Variable Name and Value: If the dimension is produced as a result of Auto Dimensions (most commonly used together with Auto Constraints), the dimension will have a variable name and value assigned to it. This value appears in Properties / Format window, as well as the Calculator Palette.

...

Note: See Auto Dimension Auto Constraint and  and Calculator Palette - Variables Palette.

...

Dimension Size Scale: The scaling factor for displaying the dimension.
Arc Length: Available for Angular dimension, displays the arc length rather than degree measurement.
Associative Dimension: Checked by default. Associative dimensions retain their positions and the dimension text will update when their associated object changes. To tell whether a dimension is associative, select the object. Any dimension associated with the object will be colored blue. 

...

Note: This parameter is only available when setting the default properties of dimension tools (see Object Properties). You will not see it in the Properties window for a selected dimension. This parameter must be set before the dimension is created.

...

Text Style: Select the Text style for the dimension. Text styles are specified in the Style Manager.
Height: Sets the height of the dimension text.
Font: Specifies the font use in the dimension text.
Color: Sets the color of the dimension text.
Frame around text: Draws a rectangular frame around the dimension text.
Fill Color: Specifies a color which will fill the text frame. The options are: None, Background and Custom. Background fills the frame with the background color. Custom allows you to select a color.
Text Position: Controls the dimension text position:
Text Movement: These options control how the dimension text is moved when editing the dimension. See Editing Dimensions.
Horizontal: Select the text alignment with respect to witness lines. The preview window displays each option. Options vary for dimension and leader text.
Dimensions - Centered
Dimensions - First Extension Line
Dimensions - Second Extension Line
Dimensions - Over First Extension Line Dimensions - Over Second Extension Line Leaders - Default Justification(Depends on the leader orientation) Leaders - Center Justification Leaders - Left Justification Leaders - Right Justification

Vertical: Select the text alignment with respect to the dimension/leader line. Outside places the text on the side of the dimension/leader line opposite the selected dimension/leader points. Above On Line Outside
Text Gap: The distance between the dimension text and the dimension line.
Adjustment: Available for VerticalOnLine position, The distance of the text above or below the dimension line. A value of zero (default) will place the text on the same level as the dimension line. Higher values move the text above the line; lower (negative) values move the text below the line.
Force Text Horizontal: Makes the dimension text horizontal no matter how the dimension is rotated.
Force Text Inside Extension Line: Keep dimension text between the extension lines, regardless of the distance between the extension lines. If unchecked, the system will decide where to place text.

...

Lines that connect the dimension line to the object being dimensioned.
Draw as Spline: If checked, the Leader tool will use a spline rather than a line to attach the dimension text to the corresponding drawing location. See Splines and Bezier Curves.
Extension: The length of the extension line segments that extend outward beyond the dimension lines.
Offset: The distance between the extension lines and the dimensioned object.
Do not Draw: Options for omitting parts of the extension lines.
Color: Sets the color of the extension lines.
Line Width: Sets the line width for the extension lines.
Line Type: Specifies the line type for the extension lines.
Generate Fixed-Length – Use the Length field to fix the length of the maximum drawn length for extension lines.
Length - Specify the length used by the Generate Fixed-Length property.

...

Alternate units are a secondary set of units for each dimension, such as 1" [25.4mm].
 
Use alternate units: If checked, the dimension and/or tolerance will be displayed with a value in alternate units, in square brackets following the primary dimension. The parameters are the same as on the Units / Tolerance page.
