Hi,
Is it possible to set parameter by name in linked model?
I want to set set value for all elements,not only for a certain category.
I want to set set value for all elements,not only for a certain category.
How can I get certain parameter value of pipes from a linked file?
Hey I was able to edit family type parameters and instance type parameters in linked files using this graph and a few python scripts. Essentially it sets the instance parameters of all elements of a given type. The true false switch allows you to edit the type parameters of all family types in a given family. I’m not sure what you need to use it for but I was using it for window and door schedules. It should theoretically work for any built in category. Also make sure you read and understand the code before using it because it’s opening files in the background and then syncing with the link’s central model. If you’re not entirely sure how to apply this to your specific workflow, then don’t use the script cause it can seriously break your model if you don’t use it right.
I’ll comment the contents of the scripts separately in a different comments because its a bit lengthy to put it all here.
