Curtainwall Mullion Material instance based

Wondering if there’s anyone who’s figured how to write a script to make a CW mullion change it’s material on an instance based? Duplicating all of my mullions seems overburdensome just to change the material.


Hi Joseph, welcome to the forum.
I don’t think what you are asking is possible. If it can’t be done with the user interface it can’t be done through the API and therefore, with Dynamo.
You could, though, use dynamo to change all your mullions to the desired type following a set of rules you define. This could save you some time (I’m not sure what your final goal is).
I checked if you could paint the mullions, which would work, but it seems it is not possible either.

One could likely duplicate the type and set the material parameter in the duplicated type without issue.
