unique ID for project

phildebrandt — Mon, 03 Jan 2011 19:28:09 GMT

Does anyone know if there is a unique ID number for projects stored in the Revit file?

I found one in the ProjectInfo.uid (see code snippit below)

            Autodesk.Revit.DB.Document actdoc = this.ActiveUIDocument.Document;
            ProjectInfo pi = actdoc.ProjectInformation;
            pid = pi.UniqueId;

However, this is the UID of the ProjectInfo object, it can be the same in 2 different Revit files.

I'm trying to find a UID that is the same for the local and central files of the same project but different between seperate projects.

Anyone know if one exists?

Hi,

This is almost the same question discussed here -> http://forums.autodesk.com/t5/Autodesk-Revit-API/How-do-you-access-a-model-s-GUID-or-UniqueId-using-the-Revit-API/td-p/3565152

I know this is an old post but I was facing the same issue and I found something that may help you. This works for Revit 2013.

UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;

string ifcproject = ExporterIFCUtils.CreateProjectLevelGUID(doc, Autodesk.Revit.DB.IFC.IFCProjectLevelGUIDType.Project);

This is the website were I found the info

I once created a dedicated add-in to address this issue:

Hi,

Fast forward 7 years, anything new with that?

Nope, sorry, no news on this front. You might want to have a look and see whether there is a wish list item for this functionality in the Revit Idea Station and vote for that...
