Architecture / Industrial Design
What the Architecture / Industrial Design domain tests
This domain assesses spatial and visual reasoning, basic geometry, scale drawing, and design principles. It tests how well you read plans, sections, and elevations and how you justify design choices with function, proportion, and context.
Core rules and concepts
- Orthographic projection separates plan (top view), elevation (front/side), and section (cut view). Line weights and hidden lines carry meaning.
- Scale is a ratio: 1:50 means 1 drawing unit represents 50 real units. Convert units before multiplying.
- Proportion and anthropometrics link dimensions to human use; ergonomics is not decoration.
- Design principles include balance, hierarchy, rhythm, contrast, and unity; sustainability includes material life cycle and energy use.
- In industrial design, form, function, manufacturability, and user safety must be considered together.
Worked example
A wall is drawn 4 cm long at scale 1:50. Find the real length. Reasoning: 1 cm on paper represents 50 cm in reality, so 4 cm represents 4 × 50 = 200 cm = 2.0 m. If the drawing were 1:100, the same line would represent 4 m. Always state the unit conversion explicitly.
Traps that cost marks
Reversing the scale, mixing centimetres and metres, reading a section as an elevation, and judging a design only by appearance while ignoring function or safety. In spatial reasoning, do not assume hidden lines are visible edges.
