ArchiCAD 15 enriches architectural  forms available for designers to unleash  their creative minds, and it also expands  the scope of the BIM workflow to include  renovation & refurbishment projects.  The evolution of forms has always  walked hand-in-hand with the evolution of  structures. From the simplest barrel  vaults to the most sophisticated rib  vaults, the architect has always aspired  to combine durability, utility and beauty  (Vitruvius). These very principles can be  seen in the finest examples of Modern  architecture as well. ArchiCAD 15  expands the design capabilities of its BIM  tools, including new Shell structures, to  support the broadest spectrum of  architectural shapes and forms found in  both classical and modern architecture.  Welcome to ArchiCAD's Interactive Training  Program. This Program is composed of a  series of easy to use and fun Interactive  Training Guides (ITG) that help users learn by  doing. These interactive training modules are  intended to expand your ArchiCAD knowledge in  broad range of topics. To get the best interactive  results, we recommend you install ArchiCAD and  complete the exercises with the help of the  narrated movie clips.
