1. Look for the "Project Janitor" group of tools under the "BD Management" tab.
2. Press the tool button that matches the type of style/pattern you want to remove.
3. Select which styles\patterns should be removed and what should be done with elements using the style\pattern.
   This is the unified workflow for all tools so it will be easy to understand and to interact with.
   At the beginning, the tool will analyze your model to get all patterns/styles and usages.
   Then you can map or even delete elements that use the pattern/style selected.
   By pressing go, it will check your selection whether it affects elements in groups or not.
   It will prompt you with a confirmation message about what is going to change in your model.
4. Press OK to commit changes back to Revit.
