When creating revisions in Revit, the options for the Revision Number are numerical or alphabetical, however sometimes both are required A1, A2, A3 etc. Revit allows you to do this using the Revision Number column if you choose the Numeric option and give it a prefix of the letter you require. See Figs 1 & 2.
When you open the revision dialogue box, you now put the revision number in the Revision field and the revision column is updated as shown below. See Fig 3.
