Renumbering Drawings in P&ID

Our process engineers have decided to rename a bunch of our P&ID drawings. I was wondering if there was a solid proven workflow to do this. I completed the following work flow on a sample project for testing purposes:

Removed the drawings from the project
Renamed them in windows explorer
Added them to the project with the new numbers (had to rename the DWG Title / DWG Number in the drawing properties)
Re-connected the OPC's (tried this but the OPC's would not populate properly therefor I blew them all away and had to add new OPC's with descriptions, to's, from's...etc.)

Is this the most efficient way to do this?
Am I going to somehow corrupt the database?
I was hoping that someone had faced this task in the past.

It seems like you have followed the corrected steps. Here are the steps I would suggest as well.


1) Open AutoCAD P&ID and open your project.

2) Select the drawings located in your P&ID folder, and Remove them.

3) Audit the project. (This will clear the database and when you copy the new drawings to the project it will populate with new drawing names.)

4) Exit AutoCAD P&ID

5) Rename the drawings in windows explorer.

5) Reopen AutoCAD P&ID.

6) Reopen your Project.

7) Right click on your P&ID Drawings folder and select Copy Drawings to Project (find the drawings you renamed) and add to P&ID Drawings folder.


This is pretty much what you did it seems. You are correct in that the Page Connectors will not connect. This is because of the change in drawing names. So, Page Connectors will have to be reconnected.


You should be fine doing it this way without having database issues. However, you could always just setup a clean new project then copy the drawings to the new project. That would ensure the database is clean.


Also, make sure you backup your project prior to doing this, just in case you need to revert to the original project.

Couldn't you just right click on the drawing within the Project Manager, and choose "Rename Drawing...." I have used this a few times, and it seems to work fine. Achieves the same end result in fewer steps, unless I am missing something?....

Hey Doug,


Unfortunately it's not that easy. The problem with that method is that the content in the drawings doesn't always update correctly. I experienced this when trying to swap 3 different drawing numbers; it created all kinds of tagging, and data issues. The method Quentin prescribes is definitely the procedure you'll want to use since it ensures data integrity of all of the drawing content.


I hope this helps!
