Display dimensions

For many applications, a map showing a feature's shape and some descriptive text is not sufficient. Precise measurements or distances are needed. Dimensions are a special kind of annotation for showing lengths or distances on a map. A dimension may indicate the length of a side of a building or land parcel, or it may show the distance between two features, such as a fire hydrant and the corner of a building.

You add dimensions to ArcGIS Pro as you would add any other data. Dimensions appear with other geographic data in the Contents pane and are drawn according to their order.

Aligned dimensions run parallel to the baseline and represent the true distance between the begin and end dimension points as shown in the following illustration:

Linear dimensions can be vertical, horizontal, or rotated as shown in the following illustration:

The functionality for editing dimensions is not currently available in ArcGIS Pro.

Dimension styles

A collection of dimension styles is associated with a dimension feature class. A dimension feature's style describes its symbology, what parts of it are drawn, and how it is drawn. Every time you create a new dimension feature, it is assigned a particular style. All dimension features of a particular style share certain characteristics, some of which can be changed on a feature-by-feature basis.

The following are the properties of a dimension feature that can be assigned based on a style:

Dimension Properties

Dimension line symbol

The symbol used for the dimension line.

Begin symbol

The symbol used for the arrow at the end of the begin dimension line.

End symbol

The symbol used for the arrow at the end of the end dimension line.

Begin dimension point

The symbol used to mark the beginning of the baseline.

End dimension point

The symbol used to mark the end of the baseline.

Dimension line display

Indicates which dimension lines should be displayed: all, begin only, end only, or none.

Arrow display

Indicates which begin and end symbols (arrows) should be displayed: begin only, end only, both, or neither.

Extension line symbol

The symbol used for the extension line.

Extension line display

Indicates which of the extension lines should be displayed: begin only, end only, both, or neither.

Offset

The distance between the dimension point and the beginning of the dimension line.

Overshot

The distance the extension line reaches beyond the dimension line.

Value to display for the text

The actual string that is displayed for the dimension text. This can be the value of the dimension only (the length of the feature or a user-specified value); the value with a prefix, suffix, or both; or a custom expression.

Arrow fit and text fit

The adjustment in the display of the arrows and text when the dimension's length is too short to show the arrows and text between the extension lines.
