A reference callout in Revit points to an existing view instead of creating a new one. It acts as a pointer that directs you to a specified view already present in the project. You can place reference callouts in various views, including:
- Plan views
- Elevation views
- Section views
- Callout views
- Drafting views
Multiple reference callouts can point to the same view, ensuring consistency and reducing duplication.
Key Considerations for Reference Callouts:
-
View Compatibility:
-
In section, plan, elevation, or callout views, reference callouts can link to cropped views of the same type as the view they’re placed in.
-
In drafting views, reference callouts can point to any plan, section, elevation, or callout view, provided the crop region is visible in those views.
-
Important: Drafting views must use reference callouts; they cannot contain detail or view callouts.
-
Crop View Parameter:
-
Ensure that the Crop View parameter is enabled in the referenced view. This guarantees proper linking and display of the callout.
-
No Parametric Relationship:
-
Reference callouts do not have a parametric link to the referenced view.
-
What this means:
-
Resizing or modifying the reference callout does not affect the crop region or content of the original view.
-
For example, if you adjust the boundary of a reference callout, the referenced view’s dimensions and settings remain unchanged.
Why Use Reference Callouts?
-
Efficiency: Reuse existing views without creating duplicates.
-
Consistency: Maintain uniformity across multiple views referencing the same detail.
-
Organization: Easily navigate to relevant details from various parts of the model.
