To Add a Reference to an Object

Use this procedure to create an entity reference from another object.

1. Open the tool palette that you want to use, and select an AEC entity reference tool.

   An AEC entity reference tool is located in the Helper Tools category of the AutoCAD Architecture Stock Tool catalog.

2. Enter ad (Add), and press Enter.
3. Select the object that you want to reference.
4. Specify a point on the original object to use as the insertion point for the entity reference marker.
5. Specify a location for the entity reference in the drawing.

   The distance between the entity reference and the reference marker is equal to the distance between the original object and the insertion point that you specified.

6. Enter a rotation angle for the entity reference, or press Enter for zero rotation.
7. Press Enter.

The entity reference and reference mark are placed in the drawing at the specified location and rotation angle. If you edit the original object, the same changes are made to the entity reference.
