Specify one alphabetic sequence per project.
If you use an alphabetic sequence for revision numbers, you can specify the characters and the order in which they occur.
To define an alphabetic sequence
- In the project, click View tab
Sheet Composition panel
(Sheet Issues/Revisions). - In the Sheet Issues/Revisions dialog, under Alphabetic Sequence, click Options.
- In the Sequence Options dialog, enter the characters to use for the sequence.
The sequence can include letters and other characters (such as *, &, and %). It cannot include spaces, numbers, or repeated characters.
If the project contains more revisions than the number of characters in the sequence, Revit uses double characters. For example, if you define the sequence abcdefghij, and a project has more than 10 revisions, Revit numbers the later revisions using aa, bb, cc, and so on.
- Click OK.
