Each one drills a different part of technical drawing, and marks what you draw.
- Orthographic projectionGiven an isometric view of a part, draw its front, top and right-side views and get specific, immediate feedback on what is wrong.10 exercises
- Geometric constructionsStraightedge-and-compass work on a grid: bisectors, equal divisions, parallels, squares, and the parabola by the rectangle method. Draw your construction lines, and the marker grades the result.10 exercises
- Oblique projectionRedraw a part as a pictorial with its front face true shape and its depth receding at 45°. Compare cavalier, cabinet and general oblique on the same solid and see what each does to the shape.10 exercises
- Reading three viewsGiven the front, top and side views of a part, build the part itself. The opposite direction to drawing the views, and a different skill.10 exercises
- Isometric drawingDraw a part the way it looks, on isometric grid paper: heights vertical, widths and depths at 30°. Given its three views, put the part back together as a picture.10 exercises
