Architects and civil engineers can use Jonny to present their 3D-ViCADo-models on their smart phones or tablets. Walking through a building, free-rotation and the resizing of perspective by intuitive gestures are basic functions offered by Jonny. Jonny enables architects and civil engineers to communicate with investors, decision-makers and producing industries in an easy and effective way. Jonny is particularly beneficial for house builders, who are now able to see their new homes at the very first beginning of the planning phase and feel at home long before the topping out ceremony is celebrated. Jonny is available free of charge to everybody. Jonny-models are produced in the 3D-CAD-application ViCADo and are freely available without a license. Note: This app can only be used with Jonny-models that are given to you by your architect or civil engineer.
