The principal benefit of IFC (Industry Foundation Classes) object-oriented file format is its object description. Not only does the IFC protocol preserve the full geometric description in 3D, but it also knows object location and relationships, as well as all the properties (or parameters) of each object. With IFC input/output, ArchiCAD can communicate with a wide range of structural, mechanical and energy analysis applications.
It is important to consider what type of information should be exported to the different disciplines. For example, structural engineers will want the load-bearing parts of the building, while an HVAC consultant will need a richer model with more internal information. Besides preparation (described above), ArchiCAD’s IFC interface enables you to filter the building information model before exporting it.
Predefined (but customizable) Translators help you apply IFC model exchange settings as simply as possible, providing “one-click” export/import solutions.
See IFC Translators.
After exporting an IFC model, it is good practice to check the IFC model in an IFC viewer. There are many free IFC viewers on the market that can be readily downloaded:
•DDS-CAD Viewer: http://www.dds-cad.net
•Nemetschek IFC Viewer: http://www.nemetschek.com
•Solibri Model Viewer: http://www.solibri.com
•Tekla BIMsight: http://www.teklabimsight.com
