BIM Janitor is a collection of tools that allow a user to remove the following clutter quickly and accurately from Autodesk® Revit® projects:

1. Line styles
2. Line patterns
3. Text styles
4. Fill in region types and
5. Fill patterns.

Except for text styles, these items are not checked by Revit's "Purge Unused" command. BIM Janitor goes beyond just checking for unused styles and patterns. It also allows a user to convert from one style\pattern to another, delete all the elements using a style\pattern and preview all the views\elements using a style\pattern before removing it. 

Key Features:

1. Analysis and Identification: BIM Janitor initiates by thoroughly analyzing the Revit model to identify all existing patterns and styles, along with their respective usages. This initial analysis provides users with a comprehensive overview of the clutter present within the project.

2. Unified Workflow: The tool offers a unified workflow across all functionalities, ensuring ease of understanding and interaction for users. This unified approach simplifies navigation and enhances user experience throughout the clutter-removal process.

3. Bulk Actions: Users can efficiently manage multiple elements by setting their choices for one style and copying them to other rows using familiar commands such as Ctrl+C or right-click and copy on the data grid. This feature facilitates bulk actions, saving time and effort for users.

4. Group Handling: BIM Janitor seamlessly handles elements within groups, notifying users of any required changes within these groups. Users have the option to either keep the group intact or ungroup it, depending on their preferences and project requirements.

5. Preview and Analysis: Prior to making any modifications, users can preview all views and elements associated with a particular style or pattern. This preview functionality enables users to assess the impact of their actions and make informed decisions.

6. Customization: The tool allows for the customization of actions, providing users with the flexibility to tailor the clutter removal process according to their specific project needs. Users can choose to delete elements, map styles/patterns, or perform other actions as required.

7. Group-Level Actions: Users can apply copy-and-paste actions to all groups, streamlining the management of elements across multiple group instances. This feature enhances efficiency and consistency in clutter removal tasks.

key benefits:

1. Streamlined Clutter Removal: BIM Janitor simplifies the process of removing clutter from Revit projects by offering a unified workflow and comprehensive set of tools. This streamlines clutter removal tasks, saving time and effort for users.

2. Comprehensive Analysis: The initial analysis conducted by BIM Janitor provides users with a clear understanding of the existing clutter within their Revit projects. This comprehensive overview allows users to make informed decisions and prioritize clutter removal efforts effectively.

3. Customization Options: Users can customize clutter removal actions according to their specific project requirements. This flexibility allows users to tailor the tool to suit their workflow preferences and project needs, enhancing overall efficiency.

4. Improved Project Performance: Removing clutter from Revit projects can help improve project performance by reducing file size, enhancing model stability, and optimizing rendering and analysis processes. BIM Janitor facilitates these improvements by offering a systematic approach to clutter management.
