Idea Generation, Drawing and Visualisation Techniques
Generating and communicating ideas
Candidates must demonstrate a range of idea-generation methods and visualisation techniques, and explain why each suits a stage of the process. Early stages favour rapid, loose exploration; later stages require resolved, annotated visuals.
Concepts to know
- Idea generation: brainstorming, mind mapping, mood boards, SCAMPER-style prompts, thumbnail sketching, collaborative ideation.
- Drawing conventions: orthographic projection (front, top, side), isometric and perspective drawing, exploded views, section views.
- Visualisation types: thumbnail, rough, refined/final presentation drawing, technical drawing, digital render, mock-up, prototype.
- Annotation: labels, dimensions, notes explaining intent and materials.
- Paraline and perspective: conveying three-dimensional form on a two-dimensional surface.
- Digital tools: vector and raster software, 3D modelling, rapid prototyping.
Common traps
- Presenting only one idea - markers look for divergent exploration before convergence.
- Unannotated sketches that communicate nothing about intent.
- Mixing drawing systems (e.g. isometric lines drawn in perspective).
- Treating a mood board as a final outcome rather than inspiration.
Rule of thumb
Match the drawing to its purpose: thumbnails to explore, orthographic drawings to specify, perspective or renders to persuade. Annotate every drawing with what it shows and why.
Worked example
Designing a lamp: begin with 12 annotated thumbnails exploring form and joint options; select three for isometric sketches with dimensions; produce orthographic views for manufacture; finish with a perspective render showing materials and context of use.
