The appearance of the Dimension markup is configurable, including its line and fill color, line width and style, opacity, and font characteristics for the caption.

To change the appearance of a Dimension markup, select it and click the Properties panel. Several properties will also be available on the Properties toolbar when the markup is selected.

Appearance Properties

Color: Sets the line color.

Fill Color: Controls the fill color of the endpoints.

Highlight: Makes the fill color and line transparent so underlying content shows through.

Opacity: Sets opacity level of the line and endpoints, from 0 (invisible) to 100 (opaque).

Line Width: Sets the line thickness in points. A setting of 0 effectively renders the line invisible.

Style: Determines the pattern of the line segment.

Show Caption: Select to include caption text on the markup. Click Edit to choose which measurements to include.

Line Start and Line End: Controls the appearance of the endpoints for each side of the line. The diagram below shows samples of each type of endpoint.

Each endpoint has an associated Scale that determines the size of the endpoint in relation to the Line Width. By default, it is set to Auto and will automatically adjust as the Line Width is changed.

Font: Sets the font used for the selected text.

Font Size: Sets the size of the font.

Text Color: Sets the color of text.

The Font Style and Script Style settings control the formatting of the text. Options include Bold, Italic, Underline, Strikethrough, Superscript and Subscript. Generally, any combination of these styles can be applied to format the text.
