IFC File – What is .ifc file and how to open it?

IFC File Format

The Industry Foundation Classes (IFC) file format is an open standard for exchanging building information between different software applications. It was developed by BuildingSMART, a non-profit organization dedicated to advancing the use of open standards in the construction industry. IFC files are used by architects, engineers, contractors, and facility managers to share data throughout the design, construction, and operation of a building.

IFC files are based on a data model that defines the objects, properties, and relationships that can be used to represent a building. This data model is constantly being updated to reflect the latest changes in the construction industry. IFC files can be exported and imported from a variety of software applications, including CAD programs, BIM software, and facility management software. This allows users to share data between different software applications and to collaborate more effectively on building projects.

Opening IFC Files with Software

IFC files can be opened and viewed using various software programs specifically designed for working with Building Information Models (BIM). Some popular options include:

• BIM Collaborator: A collaborative BIM platform that allows users to open, review, and mark up IFC files.
• BIM Viewer: A free, open-source IFC viewer that enables users to view and navigate IFC models in 3D.
• ARCHICAD: A commercial BIM software suite that supports IFC import and export.

These programs provide features for visualizing, analyzing, and manipulating IFC models, making them valuable tools for architects, engineers, and construction professionals involved in BIM workflows.

External Resources and Libraries

In addition to dedicated software, there are also online resources and libraries that support IFC file handling. These include:

• IFCjs: A JavaScript library that allows developers to work with IFC data in web applications.
• IfcOpenShell: A C++ library that can be used to read, write, and modify IFC files.
• The BuildingSMART Model Server: An online platform that provides access to IFC data and tools for collaboration and interoperability.

These resources extend the capabilities of IFC file handling, enabling developers and researchers to create custom applications and integrate IFC data into various workflows.

What is an IFC File?

An IFC (Industry Foundation Classes) file is a digital representation of a construction project that is used to facilitate interoperability between different software applications. It serves as a common language that enables the exchange of data and models among various disciplines involved in building design, construction, and operation. The IFC format defines a comprehensive schema for representing building elements, their relationships, and associated properties. This allows project teams to create and share detailed digital models that can be used for planning, design, coordination, and facility management throughout the project lifecycle.

Applications of IFC Files

IFC files are widely used in the architecture, engineering, and construction (AEC) industry. They are commonly employed for:

• BIM (Building Information Modeling): IFC files provide a foundation for BIM workflows, enabling the creation and exchange of digital models that represent the building’s physical and functional aspects.
• Interoperability: IFC files bridge the gap between different software tools, allowing project teams to collaborate seamlessly. They enable the exchange of data between design, analysis, and simulation applications, fostering a streamlined and efficient design and construction process.
• Project Documentation: IFC files serve as a comprehensive repository of project information, capturing the building’s geometry, materials, systems, and relationships. They provide a valuable record for future reference during renovations, retrofits, or maintenance operations.
