The IFC (Industry Foundation Classes) file format is an open, international standard for Building Information Modeling (BIM) data. It is developed by buildingSMART International and is intended to describe building and construction industry data. IFC files contain a digital representation of buildings, including their geometry, spatial relationships, properties, and other relevant information. This allows for interoperability between different software applications used in the architecture, engineering, and construction (AEC) industry. The format supports the exchange and sharing of building information throughout the entire lifecycle of a building, from design and construction to operation and maintenance. IFC files are structured using a schema that defines the different types of entities and their relationships, ensuring consistency and accuracy in the data. The IFC standard is continuously evolving to incorporate new technologies and industry practices, making it a crucial tool for collaborative BIM workflows.
