Creating Change Rule Sets

  • Last UpdatedNov 21, 2025

When a Change Library is created, a Change Rule Set (CRST) is not automatically created.

  1. To create a CRST below a Change Library, navigate to the RPLB.

  2. Select Create > Change Ruleset.

    The Create CRST form will be displayed, and you can give the CRST a name.

  3. When you click OK on the Create CRST form, you will see the Change Representation Rules form to allow you to define individual DCRULEs and ACRULEs and to make references from these to existing DCSTYLs and ACSTYLs.

    The Change Representation Rules form will be considered in two stages:

    • The upper part of the form is concerned with the creation and deletion of DCRULEs and ACRULEs within a CRST. If creating a DCRULE it allows you to restrict the application of a DCRULE to a specified changed element. If creating an ACRULE it allows you to restrict the application of an ACRULE to a specified changed annotation type. This part of the form is explained in Creating and Deleting Change Rules.

    • The lower part of the form displays a list of all currently defined DCSTYLs or ACSTYLs, depending on the selection made in the upper part of the form, and allows you to select any one of these to be referenced by the current DCRULE or ACRULE. This part of the form is explained in Associating Change Rules with Styles.
