Hi Guys,

Returning to a problem that has plagued me before, and hoping someone can help me with it.

I am trying to renumber elements in Revit (rooms in this instance). I have managed to create room numbers that have the unit number as a prefix, however the actual room number is just a random number assigned by Revit.

I am trying to give all numbers with the same prefix a unique number in sequence from 0 to 10. So any numbers with prefix AAAAA. will read AAAAA.01 AAAAA.02 AAAAA.03 etc. to complicate the matter, the list is not ordered. I could reorder it, export it to excel and try renumbering it there, but that messes up my selected order and the numbers no longer correspond to their element locations.

Any help would be greatly appreciated.

Thanks,

Sam
