Provide additional detail about or alternate views of various parts of a model.
In Revit, you can create reference callouts, detail callouts, and view callouts.
Reference Callouts
Use multiple callout tags in different views to refer to one callout view.
Detail Callouts
Use a detail callout when you want to provide details about a part of the building model. The detail callout provides more granular information than the parent view. You can add details and annotations to the detail callout. These details do not display in the parent view.
When you add a detail callout to a view, Revit creates a detail view. The detail view displays in the Project Browser under Views (all)
Detail Views.
For a detail callout, you can specify whether its callout tag displays in the parent view only or displays in the parent view and intersecting views. For intersecting views, you can automatically hide the callout tag if the scale is coarser than a specified value.
Furthermore, you can specify whether the detail view uses the style and offset that you specify in the detail view parameters, or the same clipping as the parent view. (Elevation and section views use the Far Clipping parameter. Plan views use the Depth Clipping parameter.)
View Callouts
Use a view callout when you want to provide more or different information about a part of the parent view.
For example, you can use a view callout to provide a more detailed layout of fixtures in a bathroom.
When you add a view callout to a view, Revit creates a view that has the same view type as the parent view.
Example
- If you add a callout tag to a floor plan view, the callout view is also a floor plan view, and displays in the Project Browser under Views (all)Floor Plans.
- If you add a callout tag to a structural plan view, the callout view is also a structural plan view, and displays in the Project Browser under Views (all)Structural Plans.
A view callout offers the same capabilities as its parent view. For example, you can specify another view to use as an underlay, assign a color scheme, and specify a view range. Use properties of the callout view to specify these parameters.
