  • web-ifc if you are interested in low-level IFC parsing, WebAssembly, Emscripten, C++.

  • web-ifc-three if you want to help us with the Three.js geometry generation.

  • examples if you want to help us by creating more example implementations of IFC.js.

  • This repository if you have ideas about cool tools that could help others develop BIM applications!

  • Try it and spread the word!

Testing files

You can find the IFC files for testing here.


You can refer your issue to the specific repository:

  • web-ifc if you have any problem with the parsing / loading (items not being readed / loaded correctly, information missing).

  • web-ifc-three if you have any problem with the adaptation we did for Three.js (efficiency, Three geometry generation, etc).

  • This repository if you have any problem with the boilerplate code it offers to develop BIM viewers.
