Introduction - E3DAD

• This project is part of the Easy 3 D
  Architectural Design project. The project E3DAD
  is a collaboration between three groups
• Design Systems Group/VR-DIS platform (Faculty of
  Architecture, Building and Planning)
• Visualization Group (Faculty of Mathematics and
  Computer Science)
• IPO, Center for User-System Interaction

4
Introduction - Early design phase

• Sketch design phase
• Preliminary design phase
• Definitive design phase
• Final (shop) design phase

5
Current drawing systems

• Current systems
• Low level graphic primitives
• Limited set of manipulations
• Architectural drawing systems
• Primitives tailored for the domain
• Build-in rules to simplify the manipulations (but
  not for the early stage of design)

6
How we can improve the early design stage?

• Theory of Generic Representation (GR)
• Design system based on GR
• Evaluation of a design system

7
Graphic Units and Generic Representations

• A well defined form of graphic representation is
  a graphic unit (H.Achten, TU/e)
• Grid
• Contour
• Axial system
• A set of graphic units is a generic
  representation
• Contour in grid
• Contour and axial system in grid
