    Unique ID's

    I have been playing around with binding files and I have noticed that when you do this, any data that was in the linked file prior to binding, seems to be removed one the file has been bound.

    Does this mean that the elements receive updated element ID's or does the information simply get deleted?

    (as I understand it)

    The ElementID is a unique "Double" value assigned to every incremental element (extending beyond user-accesible elements, so things like each line of a floor sketch gets one, etc) per model - it's not a truly "unique" value (that'd be the GUID, not exposed within Revit).

    When you bind a model, all the elements from that (at first linked) model are coming into the recieving (host) model, and so ElementIDs need to be piled in on top of ElementIDs inside said host (to avoid conflict) - so yes, essentialy "wipe" (technically rewrite) any previous ElementID (of the once-linked model).



    Question is; given ElementIDs slight lack of versatility, what workflow (employing them) will suffer because of this discovery? As in, what does the loss actually lose downstream?

      Thanks Snowy,

      Much appreciated. Makes sense.
