Add a Subcategory in Detail Item Family

[GregX]

Hello,
I have never tried it (but will try if and when I’ll have spare time) but if you have some python knowledge you could try and look at this:

create and assign subcategories in revit using python

Once you manage to get it working on one family you should implement it to work on multiple families, something like this:

Batch / Open projects or families with Dynamo

I wanted to batch edit families and have already prepared my graph that can make the changes that I want and save the file. The problem is that I can just make it with the “Current Document”. Is there a way to do it in Dynamo? In order to use DynamoAutomation I need Dynamo Studio, isn’t it? Actually, what I want to achieve is to change the font in all the Revit families? Any ideas? Should I just use DynamoAutomation? Thanks [image]
