By default, the callout head for a reference callout includes a label (such as Sim, an abbreviation of Similar). You can change this label to meet project needs or corporate standards. For example, you can use Mirror or Reverse as the reference label.
To change the reference label
You can change the way that the reference label displays in the callout tag, or add the referencing detail or sheet numbers to the callout head. To do so, create a callout head family, and add labels that use these parameters. See Creating a Callout Head Family.
