Convert IES to RFA

Understanding IES and RFA file formats

The IES file format, developed by the Illuminating Engineering Society, is widely used in the lighting industry to describe the distribution of light from a luminaire. It contains photometric data that helps in simulating how light will spread in a given space. On the other hand, the RFA file format is a Revit Family file used in Autodesk Revit, a Building Information Modeling (BIM) software. RFA files contain 3D models and associated data that are used to create building components in architectural designs.

Converting IES to RFA

Converting an IES file to an RFA file involves integrating photometric data into a 3D model that can be used in Revit. This process is essential for architects and designers who need to incorporate accurate lighting data into their BIM projects.

Best software for IES to RFA conversion

One of the best tools for converting IES to RFA is Autodesk Revit itself, as it allows users to import IES files directly into a lighting fixture family. Here’s how you can do it:

• Open Autodesk Revit.
• Go to File → Open → Family and select a lighting fixture family.
• In the family editor, go to Create → Load IES File.
• Select the IES file you wish to import.
• Adjust the lighting parameters as needed and save the family as an RFA file.

For those who prefer a dedicated conversion tool, ElumTools is a plugin for Revit that provides advanced lighting analysis and can handle IES to RFA conversions efficiently.
