Revit Tip: Revision Schedule

Using the revision feature of Revit

Revit allows for tracking of revisions and tagging clouds.











Problem

Without using the Revision feature of Revit, our drawings wind up with a chart that lists all revisions regardless of relevance to the sheet.










Solution

  1. Create a border that has a Revision Schedule in the title block. (more on this later)
  2. Create revisions in your project
    • Under settings>revisions click add:New.
    • The sequence number corresponds to revision number, so this will be displayed in your tag triangle. (more on that later)
    • Add a date and description for the Revision
    • Do not check issue until all the clouds have been created.
    • Once you move to the next revision you can change the visibility to tag only. This will hide the clouds and leave the triangle for previous versions.
  3. On a sheet, not in model space, create a revision cloud. Change the properties of the cloud to the appropriate revision that you set up in step 2. NOTE: If you have multiple clouds on the sheet they all need to be in one sketch, not separate clouds. One cloud per revision, otherwise each instance will show up in the schedule.
  4. Use the tag feature to tag the cloud as you see fit.
  5. At the start of a new revision:
    • Create a new revision in settings.
    • Check the box to issue the previous revision
    • Change the visibility for the previous revision to “TAG”
    • Add your new revision clouds.








This will also allow us to tag a cloud similar to tagging a wall. It will also allow our Revit model to track all the revisions in case we need to go back to one. Most importantly, the revision list on the title block now only shows those revisions that the sheet was issued for.










We have introduced the new automatic revision schedule to the newest template and it works great in 2009.

One thing you might not know is the ability to ‘tell’ Revit which revision a particular sheet should be shown in. Previously, we were required to place a revision cloud on every sheet for every revision for the schedule to read properly.











Instead, once all your revisions are set up in the Project information just click the sheet border and click Properties.






For the menu scroll down to the Revisions on Sheet entry and hit the edit button.







Now you can select which Revisions this sheet is included with.





Maybe in the next version they can figure out how to tie this into the drawing list…

Hi, how did you the column comments in the shedule?

I bet they just changed the "Description" field to be called "Comments" in the revision schedule embedded on the sheet.
