I'm completely new with IFC files. For my company I need to read IFC files see http://www.kleinhandel.nl/test.ifc for example. I don't know how to read this in C#. I guess I need to de-serialize it, but how?
I've found this website, but there are no downloads available :(
I use DDS Viewer to view and program modules to IFC files (using C#). Unfortunately the viewer doesn't allow write capabilities as yet. But at least you can read and at least you can view and query the model. Additionally, DDS Viewer allows Javascript access to the model.
You can find the tool here: http://www.dds-cad.net/132x2x0.xhtml
