I am very new to using Dynamo and working with graphs, but I am looking to try to change the subcategory line color via Dynamo. Looking to see if anyone else has done this before and or has a graph that I could reference.
Hi @JeremyH57,
You can use the Set SubCategory Properties node in Genius Loci package for that purpose.
Hey thank you for the Node and package reference. When I go to run the script there are no errors but still wont change the line color of the sub category. Any advice ? Like I said I am very new to Dynamo.
Hi Jeremy,
It should work. Which version of Dynamo do you use ?
Can you check that the default values are enabled ?
Alban, where you are getting “graphic style” in the set subcategory i am just getting “function” here is the version of Dynamo : 
Can you share your graph (.dyn file) ?
I will check the default values.
when I use the file you sent the Set SubCategory comes up “null”
There is a glitch with the input Material with your dynamo version.
Can you add a codeblock with a null and connect it to the input Material ?
Can you add a sample Revit file also ?
Sorry for the inconvenience. I will investigate to understand the issue.
No worries !!! I’m new at this and need the help.
Okay. It was indeed a problem with the default input. Not the Material input but the LinePattern one.
