Engineering Graphics and Computer Aided Drawing

The conventions that make a drawing readable by someone who has never met you, and then the foundation of the whole subject: representing a three-dimensional point or line by two flat views, and recovering the true length and true inclination that neither view shows directly.

Prisms, pyramids, cones and cylinders, first in simple positions and then tilted. The whole of the inclined-axis work is one repeated trick: draw it easy, then tilt it, then tilt it again — and never change a length that the tilt does not change.

Cutting a solid with a plane and drawing what the cut face really looks like, then unrolling the surface flat. Development is the topic with the most direct industrial use in the course — every duct, hopper and sheet-metal transition is made from one.

A single pictorial view that shows three faces at once, and the distinction between an isometric view and an isometric projection that the exam repeatedly tests. Then CAD — which the syllabus assesses internally only.
