Convert OBJ to RFA

Understanding OBJ and RFA file formats

The OBJ file format is a widely-used 3D model format that represents 3D geometry, including the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon. It is a simple data-format that represents 3D geometry alone, without any representation of color, texture, or other common 3D model attributes.

The RFA file format is associated with Autodesk Revit, a building information modeling software. RFA files are Revit Family Files, which contain 3D models and components used in architectural design. These files are essential for creating detailed architectural models and are used to store information about building components.

Converting OBJ to RFA

Converting an OBJ file to an RFA file involves transforming a general 3D model into a format that can be used within Revit for architectural design. This process is not straightforward due to the differences in the data each format supports. OBJ files are primarily focused on geometry, while RFA files include additional information necessary for building modeling.

Best software for OBJ to RFA conversion

One of the best ways to convert OBJ to RFA is by using Autodesk Revit itself, although it requires a few steps:

• First, import the OBJ file into a software that supports OBJ, such as Autodesk 3ds Max.
• In 3ds Max, use the File → Export option to save the file in a format that Revit can import, such as DWG.
• Open Autodesk Revit and use the Insert → Import CAD feature to import the DWG file.
• Once imported, you can save the file as an RFA by using the File → Save As → Family option.

While this method involves multiple steps, it is currently one of the most reliable ways to convert OBJ files to RFA format.
