How do I retrieve the Shared Site parameter for a Link Instance


I am trying to get the name of the shared site for each instance of a linked model. I have tried to use the GetParameterValueByName node and used “Shared Site” as the parameter name. I have also used the below Python code snippet to try and retrieve the shared site, but it returns that it has no value:

parameters.append(element.LookupParameter("Shared Site").HasValue)

The image below shows that the links indeed have a shared site assigned to them:


Here is the dynamo script I created that just returns empty-handed:


Any help will be much appreciated. I feel as if I’m missing something right in font of me.

Can you show the python code?

Hi @charl.pretorius,

This parameter value is accessible by the linkInstance name.

In python :

import clr
# Import RevitAPI
import Autodesk
from Autodesk.Revit.DB import *

import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument

rvtLinkCollector = FilteredElementCollector(doc).OfClass(RevitLinkInstance).ToElements()
for rvt in rvtLinkCollector:
OUT = names




Thanks for the solution! I would never have thought that the name property also exposes the shared site. I have trawled through the API docs and nowhere is that made clear.

It’s a pity that it’s just a string combined with everything, but luckily it’s trivial just to trim everything off before the location.


The gist of the code is in my original post, but below is the entire snippet for reference, also changed to get the parameter value as a string, which just returns empty strings:

# Import RevitAPI
import clr
import Autodesk
from Autodesk.Revit.DB import *

# Import DocumentManager and TransactionManager
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

elements =[UnwrapElement(link) for link in IN[0]]

sites = [element.LookupParameter("Shared Site").AsValueString() for element in elements]

#Assign your output to the OUT variable.
OUT = sites

5 years later, any way yet in API to change the Shared site parameter passing in a Project location?
