A callout shows some portion of another view at a larger scale. In a construction document set, use callouts to provide an orderly progression of labeled views at increasing levels of detail.
Modify Callout Views
Change the type, area, head format, and other parameters of callout views.
Adjust the Callout Leader Line
In the parent view of a callout, you can move the leader line to any point on the callout bubble.
Create a Callout Head Family
Specify a desired callout format or include specific information in the callout head by using a callout family.
Change Display Properties for Callout Tags
You can control the line weight, color, and the pattern used for callout bubbles and leader lines. The settings that you specify here apply to all callouts in the project.
Create a Reference Callout
Insert a reference callout to an existing view, or create a new drafting view.
