Introduction
Autodesk Revit is a powerful BIM tool that uses several file types to support architectural, structural, and MEP workflows. Each file type serves a unique purpose, from managing project data to storing reusable components. In this guide, we explore the most common Revit file types—RVT, RFA, and RTE—explaining their functions, uses, and how they fit into a Revit project workflow.

Overview of Revit File Types
Revit uses specialized file formats to streamline design, documentation, and collaboration. Understanding these file types is crucial for efficient project management and seamless collaboration with team members.
Primary Revit File Types:
- RVT: Project files containing design models and associated data.
- RFA: Family files used for creating reusable components.
- RTE: Template files for starting new projects with predefined settings.
1. RVT (Revit Project Files)
The RVT file is the main file type in Revit, representing a complete project, including its 3D models, 2D views, and associated data.
Key Features of RVT Files:
- Stores all design elements, including walls, doors, windows, and floors.
- Contains project documentation, such as plans, sections, and schedules.
- Supports collaboration through worksharing in a central file.
Common Uses:
- Managing architectural, structural, and MEP models.
- Coordinating designs across multidisciplinary teams.
- Sharing project files with stakeholders and consultants.
File Size Considerations:
- RVT files can become large as project complexity increases. Using linked models and purging unused elements helps reduce file size.
Pro Tip: Save RVT files regularly to avoid data loss and use BIM 360 for cloud-based backups.
2. RFA (Revit Family Files)
RFA files represent families in Revit, which are the building blocks of a project. Families are pre-defined or custom elements, such as doors, windows, furniture, or HVAC components, that can be reused across multiple projects.
Key Features of RFA Files:
- Contains parametric data, allowing users to modify dimensions, materials, and behavior.
- Includes 2D and 3D representations of the family.
- Can be loaded into RVT files for use in a project.
Common Uses:
- Creating reusable components to maintain consistency across projects.
- Storing manufacturer-specific elements with detailed specifications.
- Developing custom families for unique project requirements.
File Size Considerations:
- Overloaded RFA files can slow down project performance. Use lightweight families with simplified geometry for better efficiency.
Pro Tip: Organize families into categories for easy access, and use Type Catalogs for managing multiple variations.
3. RTE (Revit Template Files)
RTE files are templates that contain predefined settings, views, and families, allowing users to start new projects with a consistent framework.
Key Features of RTE Files:
- Includes default settings like project units, view templates, and title blocks.
- Preloaded with standard families and annotation styles.
- Serves as a foundation for new projects, ensuring consistency across teams.
Common Uses:
- Standardizing workflows in architectural firms or engineering teams.
- Streamlining project setup by eliminating repetitive tasks.
- Customizing templates for specific project types, such as residential, commercial, or industrial designs.
Pro Tip: Save frequently used templates in a shared network location for team-wide access.
Other Revit File Types
In addition to RVT, RFA, and RTE, Revit uses other file types to support specific workflows:
File Type | Extension | Purpose |
---|---|---|
Revit Backup File | .0001.rvt | Auto-generated backup files to restore earlier versions. |
Revit Link File | .rvt | Links external Revit models into the current project. |
Shared Parameters | .txt | Stores parameters shared across projects and families. |
IFC Files | .ifc | Open-format files for interoperability with non-Revit software. |
How Revit File Types Work Together
1. Linking RFA into RVT
- Families stored in RFA files are loaded into RVT files to populate a project with components.
- Example: Load a door family (RFA) into a residential project (RVT) and customize its dimensions.
2. Starting a Project with RTE
- Use an RTE file to initiate a project with preconfigured standards.
- Example: Start a commercial building project with preloaded title blocks and view templates.
3. Sharing Files for Collaboration
- Use RVT files for project collaboration. If working with external consultants, export the model to IFC format for interoperability.
Tips for Managing Revit File Types
- Organize Your Files: Create folders for RVT, RFA, and RTE files to ensure easy access and version control.
- Optimize File Performance: Purge unused families and regularly audit your files to improve performance.
- Backup Frequently: Use Revit’s auto-save feature or BIM 360 for cloud-based backups.
- Use Shared Parameters: Create shared parameter files to maintain data consistency across families and projects.
- Keep Templates Updated: Regularly review and update RTE files to align with current standards and best practices.
Common Challenges with Revit File Types
- File Size Issues: Large RVT or RFA files can slow down performance. Use linked models and lightweight families to optimize files.
- File Compatibility: Older versions of Revit cannot open newer files. Always save in a compatible format when sharing with external teams.
- Data Loss: Working without backups can result in significant data loss. Use Revit’s backup files or BIM 360 for recovery options.
Conclusion
Understanding Revit’s file types—RVT, RFA, and RTE—is essential for managing projects effectively. RVT files serve as the backbone of your projects, RFA files provide reusable components, and RTE files streamline project setup with predefined standards. By mastering these file types, you can enhance collaboration, ensure consistency, and optimize your workflow for better project outcomes.
FAQs
- What is the difference between RVT and RFA files in Revit?
RVT files are project files containing the entire building model, while RFA files are family files representing reusable components like doors or furniture. - Can I open RFA files directly in Revit?
No, RFA files must be loaded into an RVT project file to be used. - What is the purpose of RTE files in Revit?
RTE files are templates used to start new projects with predefined settings, ensuring consistency and saving time. - How can I reduce the size of RVT files?
Use linked models, purge unused families, and avoid overloading your model with unnecessary details. - Can I convert RVT files to other formats?
Yes, RVT files can be exported to formats like DWG, IFC, or PDF for compatibility with other software.
