Revit Family
CAD & 3DRFA is a Revit loadable family containing geometry, types, parameters and a category. It differs from an RVT project; inspect both Family Editor behavior and the result after loading into a project.
- Main use
- Reusable building components such as doors, furniture and equipment
- Data type
- Binary data

Opening steps
Choose your environment or purpose to see its steps.
Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- Cannot place: inspect host requirements.
- Overwrite prompt: inspect changes to existing types and parameter values.
- Older version rejects it: families also follow Revit version constraints.
- Resizing fails: inspect constraints, formulas and reference planes with the author.
RFA → supported geometry export / project use
- Retain RFA for editing; use supported CAD export when the recipient needs geometry.
- Check type names, category, units, parameters and placement conditions.
Geometry export does not preserve equivalent types, parameters and hosting behavior.
Loaded families are not external links
Loading stores family data in the project. Editing the source RFA does not necessarily update every project; review overwrite choices during reload.

Worked example: checks before handoff
Example: test equipment types, connections, hosts and dimensions in a test model before production loading.

Related-format differences
| Format / method | Purpose and preserved information |
|---|---|
| .rfa | Reusable building components such as doors, furniture and equipment |
| RVT / DWG | RVT is a project; DWG exchange does not imply family parametric behavior. |
| RFA → supported geometry export / project use | Geometry export does not preserve equivalent types, parameters and hosting behavior. |
Handling and security
Review source and embedded properties, controlling distribution of internal product/equipment information.
Questions and answers
Does RFA contain the whole building?
It is normally a reusable component, not the entire project.
Does editing RFA update every model?
It depends on reloading and overwrite settings in each project.
Is the source RFA needed after loading?
Data is stored in the project, but retain a separate RFA master for reuse/maintenance.

- MIME type
- Consult the producer or delivery system. The extension alone does not establish a MIME type.
