Change a Dimension Value
When you adjust the value of a dimension, the referenced element changes in size or moves accordingly.
Add Prefix/Suffix to a Dimension Type
Add a prefix/suffix to a dimension type. Prefix/Suffix added in this way will not need to be added to each dimension instance.
Move Text for Dimensions
When dimensions display close together, making them difficult to read, you can drag text away from the dimension line to improve clarity.
Change the Dimension Tick Mark
To meet office standards or improve readability in drawings, you can change the tick mark that displays at the ends of a dimension line.
Remove a Dimension Line Segment
In dimension strings containing 2 or more segments, use Tab to highlight an individual dimension segment for deletion.
Define Alternate Dimension Units
You can display alternate dimension units along with the primary units for all permanent and spot dimension types. For example, if you define alternate dimension units, you can place dimensions that automatically display Primary Units (for example, feet and fractional inches), and Alternate Units (for example, millimeters).
Create Custom Dimension Units
When you create a project, by default Revit assigns specific units and accuracy to dimension styles based on project unit settings. You can create custom dimension types that override these default settings.
Apply a Label to a Dimension
In the Family Editor or the conceptual design environment, you can edit a permanent dimension to apply a label.
Change the Reference for a Radial Dimension
You can change the reference of an existing radial dimension from one arc to another, provided the new arc is concentric with the original arc.
Anchor Elements Referenced in Multi-Segmented Dimensions
In a multi-segmented, equality constrained dimension, you can use the anchor symbol to designate the anchored element. The element that is anchored remains stationary while you move other elements in a dimension.
