If you have not got Vabi Elements installed, but you do want to check whether the IFC file complies with our conditions, it is best to use an IFC viewer. A good IFC viewer is the IFC Viewer as developed by TNO, which can be downloaded from http://www.ifcbrowser.com/ for free. The IFC Engine of this browser is used in Vabi Elements as well.
Another good and free tool which we advise is Solibri Model Viewer
