I’m trying to use the PublishCoordinates Method to publish linked project locations that have the same name as the host file’s project location, but I’m having trouble with the transactions.
The method requires both a transaction and a LinkElementId, the issue is that opening a transaction in the current document will not allow you to interact with the linked file(and subsequently the LocationId), transactions cannot be opened in linked files, and opening the document in the background converts the LinkElementId to a normal ElementId because the linked file is now the active file.
Has anyone successfully used this method and, how so? PublishCoordinates.dyn (14.4 KB)[ I’ve commented out my four failed attempts ]

P.S. This is a continuation of my quest to automate creating shared coordinates with only ablsolute northing, easting and elevation values.
I figured it out, my LinkedElementId constructor was missing an argument, which prevented it from creating LinkedElementID and LinkInstanceId properties that are essential in the publish coordinates method.
Hi, thx for the quick answer! I am usind Revit 2021 and Dynamo 2.6… I am now looking at the python code, perhaps I need to have the coordinate system already created in the model, with the given name in order for the node to work? I think that is the problem, I am trying to create the coordinate system with the given name upon publishing coordinates (this is my usual workflow in Rvt)
Edit: My mistake, it works like a charm. You really need to have a site with the given name already created in the linked doc. So I would need to find a way to do that
I updated the node again to work in all cases.
You must have as many Project Location Names as there are linkinstances or a unique Project Location Name for all linkinstances.
Hi, @Alban_de_Chasteigner ! Thank you very much for trying to make this work, but unfortunattely there is still an issue - the node now creates the sites if they do not exist, but it changes instances’ locations. I tried it yesterday with the previous edit and all the links were moved to the wrong locations. I just tried your last update now and half of the links were immediately moved to wrong locations again, so I had to stop its run manually. You can see on the screenshot links already disappearing:
Edit: Perhaps two separate nodes would work better, the one for publishing coordinates like it was before and another one that only creates coordinate systems in linked files by their given name?
If I understand your workflow correctly, I don’t think it’s supported in Revit.
The Publish Coordinates node creates the sites if they do not exist and publish the current shared coordinates of the host model to the linked models.
If you have several sites in the host model, those that are not active are not taken into account.
The way your node worked previously was doing just that - publishing coordinates to an existing site within the link. The only thing missing was that you already needed to have these sites created in the linked file. So that’s what I was wondering how to automate
Sorry to take so much of your time, I think I will just rollback to the initial version of your node and create the sites manually with the given names - it would take not more than an hour. Then publishing would work, I tried that already with a few instances only
I now understand your workflow better.
I updated the custom node again. This time, I’m not creating a new project location, but duplicating the active project location from the linked model and setting a new name. The link should no longer move.
If you have time to experiment with this new behavior, that would be appreciated.
