IFC SDK

The IFC SDK provides datatypes and code supporting the read and write of IFC files. This is an experimental project aiming at advancing implementation and uses of C++ Modules at large. The SDK contains C++ datatypes that can be memory-mapped directly onto the on-disk format. See the IFC Specification for more details.

If you want to participate in the development of the IFC SDK, you are welcome! You can report issues, comment on pull requests, and learn about what we are working on. You can also submit pull requests to fix bugs or add features reflecting the Specification: see CONTRIBUTING.md for more information.

Building and Running

This project uses CMake for defining projects, and the code has been tested to work on Windows and Linux. It can be built and run under WSL (Windows Subsystem for Linux) as well.

The JavaScript IFC viewer can be run by loading the index.html file in a browser.

IFC files to experiment with can be generated by using a current Microsoft C++ compiler. There are a couple of IFC files checked into the repo for basic testing purposes. Longer term, we want to be able to generate IFC files using the SDK itself. To generate an IFC file, you can use a current Visual C++ compiler. The following will generate an IFC containing almost everything in the test.cpp translation unit. Currently, non-inline functions or methods will not be generated into the IFC.

cl /std:c++20 /exportHeader test.cpp

This will create an IFC file named test.cpp.ifc. This can be dumped with ifc-printer like this.

ifc-printer.exe --color test.cpp.ifc
