About Reference Callouts

Point to an existing view using a reference callout.

A reference callout is a callout that refers to an existing view. When you add a reference callout, Revit does not create a view in the project. Instead, it creates a pointer to a specified, existing view. You can place reference callouts in plan, elevation, section, callout, and drafting views. Multiple reference callouts can point to the same view.

When using reference callouts, consider the following:

• Reference callouts in section, plan, elevation, or callout views can reference cropped views of the same type as the view in which the reference callout is placed.
• Reference callouts in drafting views can reference any plan, section, elevation, or callout view if the crop region displays in these views. Drafting views must use reference callouts; they cannot use detail callouts or view callouts.

Check the properties of the referenced view to be sure that the Crop View parameter is turned on.

A reference callout does not have a parametric relationship with the referenced view. Therefore, if you change or resize a reference callout, the changes do not affect the original referenced view. For example, resizing the boundaries of a reference callout does not affect the crop region of the referenced view.
