Manage dimension feature class properties

Dimension feature class properties are managed through a Catalog view in ArcGIS Pro.

The Feature Class Properties dialog box is used to set the alias and the spatial and attribute indexes, while the Dimension Feature Class Properties pane is used to view and manage properties unique to dimension feature classes—reference scale and dimension styles.

To open these, right-click a dimension feature class in the Catalog pane or Catalog view and click either Properties to open the Feature Class Properties dialog box or Dimension Feature Class Properties to open the Dimension Feature Class Properties pane. Note that some properties are editable, while others are read-only.

Use the fields view to manage the fields associated with a dimension feature class. You can edit the fields list, subtypes, and domains of a dimension feature class from the view.

Fields

The Fields view lists the fields in the dimension feature class. The following fields are required and can't be deleted:

  • OBJECTID
  • SHAPE: Polygon shape representing the outline of the dimension feature.
  • DIMLENGTH: Length of dimension line.
  • BEGINX: X-coordinate of the start dimension point.
  • BEGINY: Y-coordinate of the start dimension point.
  • ENDX: X-coordinate of the end dimension point.
  • ENDY: Y-coordinate of the end dimension point.
  • DIMX: X-coordinate of the dimension line height.
  • DIMY: Y-coordinate of the dimension line height.
  • TEXTX: X-coordinate of the text point (null if the text has not been moved relative to the dimension feature).
  • TEXTY: Y-coordinate of the text point (null if the text has not been moved relative to the dimension feature).
  • DIMTYPE: A value of 0 indicates an aligned dimension that displays the distance between the measure points; 1 indicates a linear dimension that displays the distance between the extension lines.
  • EXTANGLE: Extension line angle.
  • STYLEID: ID of the dimension style.
  • USECUSTOMLENGTH: A value of 0 indicates that the feature's length is used for the dimension text; 1 indicates that a custom value is used for the dimension text.
  • CUSTOMLENGTH: Value used for the dimension text if USECUSTOMLENGTH is 1.
  • DIMDISPLAY: Null indicates that both dimension lines are displayed, 1 indicates that only the start dimension line is displayed, 2 indicates that only the end dimension line is displayed, and 3 indicates that none of the dimension lines are displayed.
  • EXTDISPLAY: Null indicates that both extension lines are displayed, 1 indicates that only the start extension line is displayed, 2 indicates that only the end extension line is displayed, and 3 indicates that none of the extension lines are displayed.
  • MARKERDISPLAY: Null indicates that both dimension line end arrow markers are displayed, 1 indicates that only the start dimension line end arrow marker is displayed, 2 indicates that only the end dimension line end arrow marker is displayed, and 3 indicates that none of the dimension line end arrow markers are displayed.
  • TEXTANGLE: Rotation angle of the text specified in radians. You can rotate the text separately only if you have defined a dimension style that does not have the text set to be parallel with the dimension line.
  • Shape_length
  • Shape_area

The STYLEID field normally contains a value greater than or equal to 0. This value is the number of the dimension style in the style collection.

Reference scale

The reference scale is read-only in the Dimension Feature Class Properties pane.

Dimension styles

The Dimension Styles group in the Dimension Feature Class Properties pane allows you to manage the dimension styles. The dimension style collection lists the predefined dimension styles you can assign to dimension features when creating or editing them in ArcGIS Pro. Each dimension feature has an associated dimension style in the list. When a dimension style is edited through the Dimension Feature Class Properties pane, the original symbol is kept and a new symbol is created in the collection. You can delete a dimension style, but any features that reference it will be drawn with a red box when displayed. To view the properties of a dimension style, click the Copy and edit this dimension style button and access the properties with any of the controls in the pane. To create a style for use in the dimension feature class, click the Add dimension style button.
