    Mark Numbering

    Is there any tools out there for numbering the Mark automatically from left to right say in some kind of order and with abit of formating.

    as we use 00 for ground and 01 for first floor etc..

    so would 00-01 00-02 etc..

    Cheers

    I use the Exitech Toolkit (subscriber only) however I have used this and seem to recall it working just fine.

    There are some dynamo graphs that can do that pretty easily as well. If you're not familiar with it, this might be a good one to try to learn on.

    This is quite easy to do with Dynamo but as Chris says it would be a good one to try yourself. Some pointers to get you started;
    - Use Category nodes to select all the categories you want and put them together in a list.
    - Use that list with Get All Items Of Category, to get everything you want in the model.
    - Use the Location node to get the coordinates of everything, sort by X, Y, Z (Or get level and sort by that, whatever you want).
    - Make sequence of numbers from 1 to the total number of elements.
    - Write that into the Mark parameter of all the elements.

    However, my general advice is DO NOT USE OR TOUCH THE MARK PARAMETER IN ANY WAY
    Why? Because it is automatically filled in by Revit every time you place something so it is better to leave it alone and use a parameter that isnt.

    A common sequence of events that happens on projects;
    - Someone places a piece of equipment, an Air Handling Unit. They use Mark to number it as AHU01.
    - They tag the AHU with Mark and it looks great on the plan.
    - The project goes on, someone places some pumps in the plant room, someone makes some plumbing fixtures etc.
    - The person who modelled the AHU places a second one and numbers it AHU02.
    - Revit gives an error saying 'Elements have duplicate mark values' and they ask me what that means.
    - I look in the model and find hundreds of objects, mechanical equipment, plumbing fixtures, air terminals, whatever, all called things like AHU285...

    Just leave it alone. Make a shared parameter called 'Component Number' or something if you really want to fill in a number for every instance.

    "as we use 00 for ground and 01 for first floor etc..

    so would 00-01 00-02 etc.."

    If you did this with Mark you would have to keep updating it, as any new component will take the last number and add 1, even if it is not on the 00- level.. Better to have no data than wrong data.

    +1

    I have a (Dynamo) script to nuke all <Mark> fields of all categories pre-model release.


    +another benefit (of not using the OOTB) <Mark> - it can't also be down-pushed to children, whereas a custom one can.

    I will TRY and give it a go on Dynamo, but I am not very good on it at all.

    I also have set up the new parameters for the type mark and mark, but dont always use the mark one but starting to see why I should use it all the time.

    cheers

    as I would have to create seperate numbering for supply grilles and extract grills how would I split these 2 up as using categories just give a list of all the air terminals.

    This is where taxonomy kicks in hard. And the classifications sigh-with-an-eyeroll that people still beat themselves up over all this.

    Relying on a single field (here, the OOTB <Mark> or even an SP <Custom Mark>) to convey all that you're trying to will only lead you to madness.
