Motivation
Why do designers draw?
- Reflection-in-Action (Schön & Wiggins 1985) : seeing-moving-seeing cycle
- Restructuring & Emergence (Verstijinen 2001) : see another interpretation or alternative
- Visual Thinking and Imagery (Goldschmidt 1991) : Seeing as & Seeing that

Discussion
- Early design critiquing + freehand sketch
- Stimulate thinking, explore alternatives
- Integrate knowledge-based tools into design
- Critiques directly on drawing & various formats
- Design constraints → spatially expressed rules

Future Work
Rules - more sophisticated design rules
- express rules graphically
Domains - geometry and elementary physics
