Possible to rename line styles?

Revit API
1

I have been looking at the api but have not seem to come across a way to rename linestyles. I know it can be done with Ideate though. just thought i could try it with pyrevit.

Can this be done?

Any references would be greatly appreciated.

I think the name comes from the GraphicsStyleCategory of the GraphicsStyle.

And I think its Name IsReadOnly

Builtin line styles cannot be renamed, but custom ones yes
untested, but it should look something like

import re
from pyrevit import revit, DB

def rename_linestyles(doc, find_text, replace_text, match_case):
   lines_cat = doc.Settings.Categories.get_Item(DB.BuiltInCategory.OST_Lines)
   
   with revit.Transaction("Rename Linestyle"):
       for subcat in lines_cat.SubCategories:
           if match_case:
               if find_text in subcat.Name:
                   element = doc.GetElement(subcat.Id)
                   if element:
                       element.Name = subcat.Name.replace(find_text, replace_text)
           else:
               if find_text.upper() in subcat.Name.upper():
                   element = doc.GetElement(subcat.Id)
                   if element:
                       pattern = re.compile(re.escape(find_text), re.IGNORECASE)
                       element.Name = pattern.sub(replace_text, subcat.Name)

# then use the def

Jean-Marc is right. His code does work for this.
In fact it seems to work for any category you want to collect - you can rename its subcategories.
Super-useful.

Just tried it and it worked. Thanks @Jean-Marc :goat:
