IFC (Industry Foundation Classes)

The IFC format (Industry Foundation Classes) is an open format used to describe construction and building-related data in a standardized way. The first version was released in 1996, has continued to evolve over the years, and continues to be updated to this day.

IFC files are text-based and contain data primarily aimed at the building industry. An example of the data contained is 3D model/object geometry data. IFC files can be opened in most CAD programs and some 3D modeling programs.
