also export the 3D model and its corresponding 2D drawings to BIMx format which can be viewed on a number of desktop and mobile platforms with native BIMx viewers. License types and localizations License types Commercial, educational and fully functional 30-day trial versions can be installed with the same installer. As long as no hardware protection is present or the software is not activated with a trial or an educational serial number, ArchiCAD can be launched in demo mode. The installer files can be downloaded without registration. The educational or trial serial numbers can be obtained after registration. Commercial version is protected by either a hardware protection key or a software key. If no key is present, ArchiCAD switches to Demo mode where Save, Copy and Teamwork features are disabled (printing/plotting is still enabled, even in case the project file has been modified since opening). START Edition is a streamlined version of ArchiCAD for smaller practices or offices who don't need collaboration and advanced rendering functionality. Educational versions are protected by serial numbers. Saved files in ArchiCAD educational versions are compatible with commercial ArchiCAD versions, but carry a watermark identifying the license type. Once a project has been edited with an Educational version, the watermark will persist in the file. Trial version is a 30-day fully functional version in which you can save, print and publish projects. File formats are fully compatible with the commercial version once the copy of ArchiCAD is used with a commercial license. Otherwise the files created by a trial version are only readable by the same ArchiCAD instance with which they were created. The trial version is protected by a serial number. Languages and localizations ArchiCAD is available in a number of localized versions. In addition to a translated user interface and documentation, these versions have a set of parametric objects (object libraries) developed considering the specific requirements of the regional market, and different default values for object properties, menu arrangements, etc. Extensions Various free and commercial add-on products and extensions add extra functionality to Archicad or provide further data exchange possibilities with other software applications. Some of these extensions are developed by Graphisoft, such as the freely available Trimble SketchUp, Google Earth or Maxon's Cinema 4D import/export add-ons or other extensions sold separately such as Graphisoft MEP Modeler, Graphisoft EcoDesigner or Graphisoft Virtual Building Explorer; while there are a number of add-ons provided by
