The development team by KeyShot did a great job by the new version of KeyShot 3 and now they released updated plugins for KeyShot. They’re now taking your models directly from SolidWorks, Pro/E, Creo, Rhino and SketchUp right into both KeyShot 2 and KeyShot 3. The main feature of all the plugins is that it will allow you to import your models with both the colors you assigned to it and the assembly/group/layer structure you gave it.
All plugins are free of charge and you will just need one of the supported software packages to get them running. More information about the new features inside all plugins you can read following the link bellow.
