What is an IFCZIP file?

An IFCZIP file is a compressed Industry Foundation Classes (IFC) file used by various CAD programs for building and construction project data exchange. It contains an .IFC or .IFCXML file, compressed to reduce file size for efficient storage and digital transmission. The compression makes it easier to archive and share detailed building information models (BIM).

More Information

The IFCZIP format is widely used in the architecture, engineering, and construction (AEC) industry, so workers often encounter IFCZIP files when exchanging complex BIM data. For example, construction professionals, architects, and engineers may generate IFCZIP files when exporting or saving project files from CAD applications to reduce the overhead associated with handling large data sets.

How to open an IFCZIP file

You can open IFCZIP files with Tekla BIMsight in Windows, but the software is discontinued. You can also open IFCZIP files with a ZIP utility, such as Windows File Explorer or Corel WinZip, to extract the contained IFC or IFCXML file, which you can then open with compatible IFC software.
