One of the ways in which the wrapping of walls may be controlled in doors and windows is by creating a reference plane and setting its Wall Wrapping property to true.
As an illustration, consider a typical door family. Here a reference plane was placed in the ground floor plan view, named “Wall Wrapping Plane”. Notice the wall wrapping property of the reference plane is set to “True”. Create a family instance parameter for offset of the reference plane.
Dimension the offset of the reference plane from the face of the wall.
Select this dimension and label it with the parameter that was created for wall wrapping.
The dimension will now display the parameter name.

Load this family into a project where it is placed in a wall that has both the interior and exterior walls wrapping at inserts.
Notice how the interface of the wrapping is attached to the wall wrapping reference plane (and this is controlled by the Wall Offset parameter).
If this parameter is changed the wrapping changes appropriately. Here it is shown at the zero extreme.
If the offset is taken outside the bounds of the wall, Revit recognizes this and generates an error message.
The first message is generated with reference to a project dimension, but as is shown in the second image, even if the dimension is not present, the offset out of the wall bounds is not accepted.
Notice that in the opposite offset direction it is possible to offset the wrapping beyond the wall bounds, but there is a limit where the functionality breaks down. In this case the wall is 264mm thick and the offset is designated as 276. Still, the wrapping still performs as required.
Note what happens when the offset is taken 1mm further! The wall structure definition disintegrates.
Be careful with this functionality then, since Revit does not recognize when the offset is out of bounds.
