CAD design documentation

Technical Drawing: Communicating Design Ideas – Technical drawing is a shared visual language for showing the exact shape and size of an object. Designers start with freehand sketches, then use pictorial views (isometric, oblique) to show the object in 3D, and orthographic projection (front, top and side views) with standard lines, dimensions in millimetres and a scale so that anyone can make it. Today most drawings are made with CAD software.

Additive manufacturing

3D Modelling: From a Cube to a Printed Object – A 3D model is a shape stored in a computer as points (vertices) joined by edges into flat faces: a mesh. We build models by starting from simple shapes (primitives), moving, rotating and scaling them, and pulling faces out (extrude). Then we add materials and lights and the computer renders a picture. The same model can be sliced into thin layers and built by a 3D printer, or used in games, films, VR and product design.

Automated systems and IoT

Robotics: How Robots Sense, Think and Act – A robot is a machine that senses the world, decides what to do with a program, and acts with motors. It has a body (structure), sensors, a controller, actuators, a transmission such as gears, and a power supply. Robots help in factories, hospitals, farms, homes and space.
