A common argument when adopting the British BIM standards in Revit is that “Revit can’t do P01, P02” etc. I’ve read and seen a lot of articles where people use other columns of the revision schedule to fake the numbering.
There is a much easier way. As with all these things, it’s not 100% to the letter of law, but it’s easy and it works.
1. Open the Sheet Issues/Revisions dialog from the View > Sheet Composition > Revisions.
2. Click on Numbering options > Numeric…
3. In the Prefix field, type P.
4. OK everything and carry on revising as normal.
You’ll now have revisions P1, P2, P3, etc. It’s that simple.
Of course, that doesn’t allow you to use a leading 0, but everyone knows P1 is P01. You can’t do the additional WIP revisions of P01.01, P01.02 but then why would you be recording these on a sheet?
When you change to Construction revisions (C1, C2, etc), simply clear the revision schedule, edit the Prefix and off you go again!
