About Associating the Attachment of a 3D Annotation Shown in a Drawing
Associativity of attachment is maintained only for annotations that meet the following criteria:
• Annotations must be attached to geometry.
• Annotations must use an annotation plane that is not flat to screen.
Some model annotations, such as symbols, surface finishes, set datum tags, and dimensions that are shown in a drawing have bidirectional associativity of attachment references. That is, when you change the attachment references of 3D annotations in a model, the references of the shown annotations are updated in the drawing. Similarly, when you change the attachment references of the shown annotations in a drawing, their attachment references are updated in the model as well. For such annotations, on the Dependencies tab of properties dialog box of that annotation, the References driven by model option under the Attachment area is always selected.

 You cannot modify the attachment references of certain shown annotations in a drawing. |
Some model annotations, such as notes and geometric tolerances shown in a drawing can have attachment references that can be made independent of their 3D attachments. For such annotations, you can decide whether or not to retain the reference associativity.
When you add, delete, or change the attachment references of a shown annotation that supports independent attachment references in a drawing, a confirmation dialog box appears indicating that the attachment reference associativity of the shown annotation with its associated 3D model will be broken.
