Which term refers to a freehand drawing used early in the design process to quickly communicate ideas without focusing on accuracy?

• A. Concept sketch
• B. Annotation
• C. Primary research
• D. Isometric drawing

Answer: (A)

Rough, freehand sketches are used early to capture and communicate ideas quickly without worrying about precision. This kind of drawing focuses on ideas, layout, and overall concepts rather than accurate details or measurements, making it ideal for brainstorming and sharing concepts with others early in the design process.

An annotation is just notes added to a drawing, not the drawing itself, so it doesn’t serve as the quick, visual idea of a concept. Primary research is about gathering information and data, not creating sketches. Isometric drawings show a more precise, scaled 3D representation used later for development, not for rapid idea communication in the early stages.
