Workflow Integration:

1. Access: Launch the plugin from the Add-ins tab in Revit's ribbon interface
2. Selection: The tool automatically loads all families from your current project, displaying them in an organized, searchable list
3. Filtering: Use the search box to quickly locate specific families or family types you want to rename
4. Batch Operations: Select multiple items and apply consistent naming rules using prefix/suffix tools or find/replace functionality
5. Preview: Review all proposed changes in the interface before committing to ensure accuracy
6. Apply: Execute the renaming operation with full transaction support and automatic rollback on errors

Integration with User Workflow:

• Fits seamlessly into project setup phases when establishing naming standards
• Supports ongoing project maintenance when family libraries are updated
• Enhances collaboration by ensuring consistent naming across team members
• Reduces quality control time by eliminating manual naming inconsistencies

Installation: The plugin installs as an Autodesk Bundle to C:\ProgramData\Autodesk\ApplicationPlugins\. The installer automatically detects your Revit versions (2019-2026) and configures appropriate components. No manual file copying required.

Requirements:

• Windows 64-bit operating system
• Revit 2019, 2020, 2021, 2022, 2023, 2024, 2025, or 2026
• .NET Framework 4.7.2 or higher
• Administrator privileges for installation

Uninstallation: Remove through Windows "Add or Remove Programs" or delete the bundle folder. All plugin files are contained within the bundle directory for clean removal. No registry modifications or system file changes are made.

Post-Installation: The "Family Rename" button appears in Revit's Add-ins tab after installation. Restart Revit if the button doesn't appear immediately.

Technical Specifications:

Built with .NET Framework 4~8 for optimal Revit integration

Uses Revit API transaction management for safe operations

Implements comprehensive error handling and rollback mechanisms

Memory-efficient processing for large family libraries

Development Standards:

• Follows Microsoft C# coding conventions
• Comprehensive unit testing coverage
• XML documentation for all public APIs
• Modular architecture for easy maintenance and updates

Performance:

• Optimized for projects with thousands of families
• Minimal memory footprint during operation
• Fast search and filtering algorithms
• Efficient batch processing with progress indicators

Compliance:

• Adheres to Autodesk development guidelines
• Compatible with Revit's security model
• No external dependencies or third-party libraries
• Respects Revit's undo/redo functionality

Updates: Regular updates ensure compatibility with new Revit versions and incorporate user feedback. Update notifications provided through the plugin interface.

Licensing: Commercial license included with purchase. No recurring fees or subscription requirements.

Current Limitations:

• System Family Protection: System families (walls, floors, etc.) cannot be renamed - this is by design to protect model integrity and follows Revit API limitations

• Large Project Performance: Projects with 10,000+ families may experience slower loading times during initial family list generation

• Undo Limitations: Due to Revit API constraints, family renaming operations cannot be undone using Ctrl+Z. However, the plugin maintains its own change history for reference

• Network Projects: When working with Revit Server or BIM 360 projects, ensure proper synchronization before and after renaming operations

• Special Characters: Family names containing certain special characters (< > : " | ? * \) may require manual validation

Workarounds Provided:

• Progress indicators for large project operations
• Comprehensive preview system to verify changes before applying
• Built-in validation to prevent invalid character usage
• Detailed error messages with suggested solutions
