Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public static View CreateCallout(
	Document document,
	ElementId parentViewId,

	XYZ point1,
	XYZ point2
)

Parameters

document Document
The document to which the new callout will be added.
parentViewId ElementId
The view in which the callout appears. Callouts can be created in FloorPlan, CeilingPlan, StructuralPlan, Section, Elevation, and Detail views.
viewFamilyTypeId ElementId
The id of the ViewFamilyType which will be used by the new callout ViewSection. Detail ViewFamilyTypes can be used in all parent views except for CeilingPlan and Drafting views. FloorPlan, CeilingPlan, StructuralPlan, Section, and Elevation ViewFamilyTypes may be be used in parent views that also use a type with the same ViewFamily enum value. For example, in StructuralPlan parent views both StructuralPlan and Detail ViewFamilyTypes are allowed.
point1 XYZ
Determines the extents of the callout symbol in the parent view.
point2 XYZ
Determine the extents of the callout symbol in the parent view.

Return Value

View
The new callout view. The view will be either a ViewSection, ViewPlan or ViewDetail.
Exceptions
Exception Condition
ArgumentException Non-reference callouts are not allowed in parent views of this type. -or- Callouts of the supplied ViewFamilyType are not allowed in the parent view. -or- point1 and point2 do not differ when projected onto a plane perpendicular to the view direction. -or- Callout view creation is not allowed in this family.
ArgumentNullException A non-optional argument was null
ModificationForbiddenException The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
ModificationOutsideTransactionException The document has no open transaction.
Remarks
The extents of new callout are determined by using the two argument points as the opposing corners of a rectangle which is aligned to the directions of the parent view. The callout's near and far cut planes will match those of the parent view. The new view will receive a unique name.
