Can not delete Subcategories in Imported Categories

Sometimes it happens that Subcategories are not deleted when you remove the DWG from your project or family. In the Visibility Graphics these Subcategories are stored and there is no way to purge this (even through Object Styles and remove it does not work). How to erase these items...

  1. Start AutoCAD

  2. Create a drawing with the exact same Layer names as you can find in the Subcategories

  3. Draw on each Layer a Line

  4. Go to Revit

  5. Import this AutoCAD drawing in your Revit project or family

  6. Select the Imported drawing

  7. Use Query and select one of the lines

  8. Press the button Delete

  9. Repeat step 7 and 8 for each layer

Now, your Revit project or family is completely purged from these Subcategories!
