The file extension IFC marks files in the so-called Industry Foundation Classes format. It is an open building standard for the digital description of Building Information Modeling (BIM). Ifc files contain the 3D model data of a building or its furnishings including elements such as windows, walls, floors as well as their attributes, materials and shapes. In addition, the entire logical structure of the building is displayed in an IFC file.
IFC is the standard exchange format for building data and is used, for example, in CAD, static and energy calculation software.
IFC is the default version of such files. In addition, IFC files in the XML standard are provided with ifcXML and ZIP-packed IFC files with the extension ifcZIP. It should be noted that there are different versions of the IFC standard and older programs may have problems reading an IFC file.
Most often resolving problems with opening IFC files is very simple. Just install an appropriate program that supports such files. All of the listed programs support IFC files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of IFC files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate IFC files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Adobe Acrobat applications is not on the list, select "Browse" option in order to manually locate the directory where Adobe Acrobat has been installed.
Sometimes problems with opening IFC files may not lie with the application itself, but can arise due to other causes, such as:
