Renumbering rooms and doors within Revit Architecture can be a tedious and frustrating process. This free tool from CTC makes the process easy.
Now you can quickly and easily renumber your rooms in an alphanumeric sequence. This tool allows the user to define the numbering sequence, and does not randomly auto-number like other tools. Revit Renumbering is customizable and allows you to add separators and suffixes to the room number format. The auto-swapping feature will ensure there are no duplicate room numbers. The status text will display the next room number in sequence so the user can monitor the changes. The user can also undo individual room numbers.
Now you have the choice to either number doors sequentially, or number them based on the room data. The sequential option numbers doors independent of the room number, and the tool remembers the previous door's number and will maintain the proper sequence on subsequent doors. Room-based door numbering permits auto-numbering using the “From Room” and “To Room” property of the selected door. Revit Renumbering automatically clears the door memory at the end of the Revit session, or allows the user to clear the memory with the simple click of a button.
Update: This tool has been rolled into CTC's BIM Project Suite as one of the free tools.
