3.1 Drawings and information conveyed by drawings.

• Computer-aided design models
• Freehand sketching
• Orthographic projection (first angle, third angle, section, assembly, general arrangement)
• Exploded views
• Block diagrams
• Flowcharts
• Circuit diagrams
• Schematics (wiring diagrams, pneumatics, hydraulics)
• Title block
• Projection symbols, view (elevation, plan, end, section, auxiliary)
• Types of line (outlines, hidden detail, centre line, projection, dimension, leader, construction)
• Surface finish
• Manufacturing detail
• Standard features (screw threads, nuts, bolts, pins, repeated items, counterbore, countersink, centre mark)
• Abbreviations (across flats, centre lines, diameter, drawing, material, square, chamfer, countersunk, hexagon head, radius, thread, undercut, pitch circle diameter)

3.2 Dimensions and tolerances on engineering drawings.

• Dimensions (linear, diameter, radius, angular)
• Tolerances
• Limits and lifts
