Technical Drawing Simulators

Reading and drawing a part is one of the hardest skills in technical drawing, because you have to imagine a solid from flat drawings. These simulators cover the whole path. First you rotate a real part in 3D and compare it with its front, top and side views, in first-angle projection, the system used in Europe. Then you move on to isometric and oblique drawing, from choosing the right part to drawing it on an isometric grid. Finally you dimension parts by tapping their lines and try standard scales on an A4 sheet. I built them so that every answer is checked instantly, before you pick up paper, pencil and ruler.
