C# classes to generate and parse OpenBIM IFC (Industry Foundation Class) files

These classes simultaneously support IFC2x3, IFC4 and Infrastructure proposals for IFC5, and are easily extended for experimental extensions.

Documentation on these classes is available on Building Smart websites, such as http://www.buildingsmart-tech.org/ifc/IFC4/Add1/html/ (Browse Alphabetical Listings)

For a list of software/applications supporting IFC interaction, refer to http://www.buildingsmart-tech.org/implementation/implementations/plominoview.allapplications

Implementataion of ifcxml is in early stage of development.

Projects to demonstrate the classes include https://github.com/jmirtsch/GeometryGymIFCExamples https://github.com/BuildingSMART/IfcScript

Please contact me in advance of making significant changes to the core code, as it's possible existing code might be ported to the open source repository if I've already implemented it.
