    Question Sheet Issue/Revisions - Individual revision requirements of each sheet in a project.

    Hi,

    I'm relatively new to Revit (I've taken a course and done over 20 hours of independent revision) so I'm still getting my head around actually using and understanding the interface.

    I've been tasked with setting up the templates and families for my work and am having issues with the revisions. We are a M+E construction company so typically we issue packages featuring every drawing in the project, but then issue revisions as needed. As we often issue Mech and Elec separately, our revisions can be as below, with different dates and revision numbers depending on whether it is Preliminary, Tender or Contract.

    Electical

    P1 01.02.18
    P2 07.02.18
    P3 14.02.18
    T1 21.02.18
    T2 28.02.18

    Mechanical

    P1 01.02.18
    P2 05.02.18
    T1 21.02.18
    T2 25.02.18


    I can customize the Numbering sequence but my problem is that I can't have two different revisions of the same name. Currently, the only solution I can find is working as Per Project and in the sheet's Properties>Identity Data>Revisions on Sheet, selecting which revisions are relevant. Per Sheet overwrites the Numbering which won't work when, as above, we don't issue a P3 drawing for the Mechanical. To maintain the correct issue date to each sheet, I've tried adding E or M to the Numbering and treat every issue individually in Sheet Issues/Revisions (shown below).

    Sheet Issues/Revisions

    Seq 1. EP1 01.02.18
    Seq 2. MP2 05.02.18
    Seq 3. EP2 07.02.18
    Seq 4. EP3 14.02.18
    Seq 5. T1 21.02.18
    Seq 6. MT2 25.02.18
    Seq 7. ET2 28.02.18

    Electrical

    Seq 1. P1 01.02.18
    Seq 3. EP2 07.02.18
    Seq 4. EP3 14.02.18
    Seq 5. T1 21.02.18
    Seq 7. ET2 28.02.18

    Mechanical

    Seq 1. P1 01.02.18
    Seq 2. MP2 05.02.18
    Seq 5. T1 21.02.18
    Seq 6. MT2 25.02.18

    Ideally, the Sheet Issues/Revisions dialogue would be individual to the sheet that is open so I can apply a numbering sequence to each as needed, but as it is the project overall this is the best solution I can find.

    Let me know if you have any ideas!
    Thanks in advance

    An option to consider might be not using the "revision number" to hold your revision number. We have a couple projects where we are managing revisions to different issued packages at the same time. To handle it I've modified our revision schedule and tags to display the "Issued To" parameter (which we don't use). Your numbering scheme is more complex, so you'd have to test how you could best manage order, and dealing with which revisions are issued.

    I would suggest using the revisions as Revit intends them to be used (good advise for everything else in Revit). If you don't it will either end up with a lot of extra work or mistakes in the future.

    What you will be able to do is get rid of the P, T and C in the revision numbers and use a phase in your project. Meaning that in the P phase (and add that to your titleblock somewhere) you have 1 issue date and start your revisions with A, B, C etc. and a date of course that is shown on your sheets. Then when you move out of the P phase to the T phase, remove all revisions, add a new issue date to the sheets and start your revisions with A again. And the same goes for the next phase. The revisions are per sheet in this case and not per project.

    You can use M er E in the description of the revision maybe, so you can more easily find them in the list of revisions and you can check if there are only E revisions on a E sheet. Something like:
    M | Changed this and that
    E | Changed some stuff
    E | More changes
    M | And even more

    This way you won't have to do manual sequences in your project (manual is scary). Sure it might be different then what you are used to, but so is the software you are working with and having all this stuff sorted for you mostly automatically is what is one of the benefits from Revit.

    AND of course, welcome to the forum !

    I hope when you use the term "Phase" you aren't referring to Revit phases? If you add Revit phases your drawings would change. If the timing works you could certainly archive the model, delete revisions and start over, but you still won't be able to have P2 sheets with different dates. While one way of managing it would be to have separate models for mechanical and electrical I wouldn't go down that route unless separate models are required by your client. (I don't do MEP, but everything I've heard suggests that there is more benefits to having them in the same model)

    NO of course not, I mean overal project phase, so the Preliminary, Tender or Contract sj3girl is talking about.

    But I do suggest to archive your project, get rid of the revisions, add a new issue date and start over with the revisions if you want to hold on to those phases (for a lack of a better word), but also forget the P2 revision and just use the system Revit has build in (let Revit sort out the revision numbers on a per sheet base and just use A, B, C, D, etc.)

    You can also have the M and E in the same model, but like I suggested make revisions with a description having the M or E in them, so you know which one to choose when adding them to your sheet or adding a Rev Cloud.
