Amiria Gale High school Design and Technology students often need to produce complex technical drawings using a compass, setsquares, T-square, and drawing board, demonstrating a range of technical drawing skills. This includes the ability to bisect angles, proportionally subdivide lines, enlarge items, find centre lines, construct tangents and tangential arcs, and use a compass to construct geometric … Read more
High school Design and Technology students are often required to construct developments (nets) of simple geometric objects, such as cubes, prisms, cylinders, and cones. This article introduces how to draw a development using a drawing board, set squares, T-square, and compass. What is a development (net)? A development or net is what an item would … Read more
Design and Technology students often have to render their drawings using graphite pencil, coloured pencil, marker pens, and other graphic mediums. This article provides an introduction to rendering to help students create drawings that accurately represent material, surface texture, and 3D form. What is rendering? Rendering means to apply tone or “shading” (light and shadow) … Read more
High school Design and Technology students are often required to understand, interpret, and draw in isometric, including isometric circles, arcs, and other curves. This article provides an introduction to isometric and concludes with sample examination questions. What is isometric? What is isometric used for Isometric creates three-dimensional representations of an object or scene. Designers commonly … Read more
Planometric is a pictorial (3D) drawing method where the base and plan view (view from above) are tilted over at 45° × 45° (or sometimes 60° × 30°), with the sides projected vertically downwards/upwards. The base and the top of the object retain their true shape.
A simple introduction to one-point perspective and two-point perspective drawing for high school students. What is perspective drawing? Perspective drawing is a pictorial (3D) drawing method that represents how things appear smaller as they get further away. It is one of the most realistic drawing methods and is often used for final presentations to show … Read more
Sectional drawings show what an object looks like as if it had been cut open or sliced through. Nut and bolt guidelines: In exams, which follow conventional British drawing standards, bolts are referred to like this: M10 × 45. The M means metric, the 10 means the outside/largest diameter of the thread is 10mm. The … Read more
Many high school Design and Technology students are required to draw exploded drawings, which show components ‘pulled apart,’ so you can see how the items fit together. An exploded drawing is often isometric or orthographic (but can be other methods, such as planometric too). Guidelines for exploded drawings: Note: You must be able to read … Read more
