Found that the issue is with GUID. While using dynamo to populate this new GUID is been created as this is treated as a new parameter rather than an existing one. Here is the task
Step 1: I have a Revit title block family where it has some shared parameter
Step 2: I load this family into the Revit file and linked the shared parameters using shared parameters from the manage
Step 3: now I want to push these shared parameters from shared parameters.txt to project parameters
I am trying to automate step 3 any suggestions?
