Chapter 5 Using Dimensions And Constraints; Dimensions; Temporary Dimensions - Autodesk 24000-000000-9860 - Revit Architecture - PC User Manual

Using Dimensions and
Constraints
Dimensions are view-specific elements that show sizes and distances in a project. There are 2 types of dimensions: temporary
and permanent.
Constraints are non-view specific elements that can function independently of dimensions. Constraint elements appear
in all views in which their references are visible; dimensions are view specific. You can modify and delete constraints
independently of dimensions or remove them when you delete dimensions.

Dimensions

Dimensions are view-specific elements that show sizes and distances in a project. There are 2 types of
dimensions: temporary and permanent.
Revit Architecture places temporary dimensions as you place components. You create permanent dimensions
to define a particular size or distance. Each dimension type can be modified, and the component that is
dimensioned updates accordingly.
Temporary and permanent dimensions, by default, use the unit settings specified for the project. For
permanent dimensions, you can create custom dimension types that override the default unit settings. See
Creating Custom Dimension Units

Temporary Dimensions

As you create or select geometry, Revit Architecture displays temporary dimensions around the component.
This is useful for placing the component in the proper place.
Temporary dimensions are created to the nearest perpendicular component and increment by the set value.
For example, if you set the snap to 6 cm, the dimension increments in values of 6 cm as you move the
component to place it. For information on changing the dimension snap value, see
on page 494.
After you place a component, Revit Architecture displays the temporary dimensions. When you place another
component, the temporary dimensions for the previous component disappear to reduce clutter. To view the
temporary dimensions of a component, click Modify and select the component. Remember, the temporary
