We have a model that for some reason has thousands of the SubCategory in Object Styles Detail Items called “+ 1 Gray Pen 1”.
I would like to select them and delete them but am having a problem getting the subcategory selection in Dynamo.
The subcategory “+1 Gray Pen” is not found. I am obviously doing something wrong. How can I structure the graph to select the desired subcategory?
Thanks.
Node “FilterByBoolMask” work in ather way. In “mask” you need connect list of boolean parameters, like: false, false, true …
Can you show code in python node (after Flatten node)?
(Sorry for my bad english 
)
To clarify- you use FilterByBoolMask as below
The Python script must convert the names to human format
Hey Benjamin.
I am having a similar problem but have not figured out how to delete a subcategory. Have you found a solution?
I can get the names as strings of subcategories, but to get the id and delete the subcategory/all elements of it itself?
Robert
In Revit 2017 your are able to batch delete the line style sub-categories.
I see. It works but still looking to make it automatic without manual labour.
How did you get the String Names of the Object Styles?
I have tried python subcat.Name.ToString()
but thats just giving me an error.
