Title block integration: Ideally the revision should be synchronized back to the drawing title block automatically to ensure that the system and the drawing file are kept aligned.NOTE: To open DWG.Automated revision numbering: Each time a drawing goes through workflow, the major and minor revision should be automatically incremented by the system to avoid the need for somebody to remember to make the change manually.For reference, the relevant section of the guide is 5.1 (Revision Control during Work in Progress - WIP).ĭrawing Management Systems such as Lunr and Meridian make it easier to follow best practices like this with engineering drawing specific features. This kind of minor revision scheme is consistent with the guidance of outlined in the UK BIM framework ISO 19650 Part 2 around revision management within a CDE (Common Data Environment). This is often referred to as minor revisions and is represented with a format like alpha.numeric like A.1 or 1.1. One last thing to note is that during a single change cycle on a drawing, the file may go through a number of iterations as it's reviewed and adjusted to meet the project requirements. Revision numbering schemes like this are a useful method to ensure that everybody understands exactly where a drawing is at in its life-cycle at any point, and helps avoid costly errors and lost time. Once it's submitted as-built it would then move to revision 1. In these sequences, the letter "O" and the number "0" are removed from use to avoid ambiguity between the two.Īs an example, drawing ME_501_A_001.dwg may start as revision A, and go through to revision D during the project phase. One that we commonly see is to use alpha characters (A - Z) for the drawing revisions prior to when the drawing is released as-constructed, then move to a numeric numbering system for operations and maintenance changes. There are many kinds of revision numbering schemes. ![]()
