Release 1.4.0 final

Release 1.4.0 final is out. You can find it on It is the first release where we are able to combine IFC 2×3 and IFC4 in the same database. Users are now able to have a project with models from different structure. For example the architect in IFC2x3 and the Construction Engineer in IFC4.

We could only test the IFC4 feature very basically. We received a couple ofIFC4 models from users, and found some test models on the internet. Some of these models where not valid IFC4 because they did not comply to the schema. When you have IFC4 files, please send them to us for testing. We will also   put up a public demo/test  server soon.

Because of the collaboration with, the plugin is now shipped with the BIMserver release.

Besides the main new feature of IFC4, there are improvements on performance and stability. We intent to release updates of the 1.4.0 version with a date stamp. So keep watch of those on github.
