This application is divided into two sections, one being a 1st and 3rd angle projection tool and the second a game. This is not a drawing tool i.e. you cannot draw in this app. The projection tool allows you to project isometric models onto a projection tool so that four orthographic views of the model can be shown. Clicking between 1st and 3rd angle changes the orthographic views automatically. The game is based on helping you understand the position of the orthographic views. Correctly answering the questions will allow you to move up a level. Points are allocated for correctness and speed.
