I found the following thread but I was hoping a new thread may keeps things clear.
I was able to hide all instances of a specific dimension style throughout the views in the my project.
After I have run the Hide Elements node, I have not been able to get all of the elements to unhide via the Unhide Node. One of the three test elements does unhide but not the other two.
I’ve tried closing Dynamo and re-running the Unhide Node but nothing seems to work. I have to manually go into the views in Revit and unhide the dimension instances.
Any advice is appreciated!
