BIM Vision

BIM Vision is a free IFC model viewer. It allows you to view models from CAD systems such as Revit, ArchiCAD, Graitec, DDS-CAD, Tekla, VectorWorks, Bentley and others, without the need to purchase a commercial license for these systems.

Bim Vision displays models in IFC 2×3 format. It has many built-in review resources and is one of the first viewers with an open programming interface.
