I have modeled a panel in a pattern-based generic model family, then created a mass using In-place mass inside a project template, finished the mass Mode, and finally, I tried to set parameter value for the generic model parameter but failed, the error says Parameter is Read-only, the Parameter is instance parameter, and the family is shared.
I appreciate you taking the time to answer my query, I am aware that the workflow I have followed will always generate that error, and I was wondering if somehow there is a script (Python…etc.) has been developed to access the family instances parameters, or maybe someone can provide a different workflow as a workaround for this problem.
The only solution that I could think of is to associate the parameter I want to set for every instance (Panel) in the curtain grid with a new parameter in the project environment, which I believe is a non-practical solution since I will have to create over 100 parameters for this element.
This is maybe the 5th family I have worked on so far, I have tried a couple of options including an Adaptive component family inserted in a pattern-based generic model, so I won’t mind a different workflow with extra effort.
I am really sorry for the late reply, I already know that your solution will work since you have suggested placing all the components in the Project Environment, but I am just waiting to try your solution myself before hitting the solution button (I know I will). What I like most about your solutions is that you prefer sticking to the OOTB nodes… many many thanks for your effort and time
For the members who is facing the same problem & have stumbled on this post, if you prefer using the Packages try using “Orchid Package: (Parameter.Associate) Node”, or a Python Script done by @awilliams
the bad news is that the Python script above was done in 2018, so I am not sure If it works with the recent Revit API, so I guess someone will have to modify it.
I haven’t had the time to try any of these solutions above, when I have time I will definitely try them all and give my feedback/update on this post.
