Challenge

• How to support architects with a computer tool in the early stages of design?

Page 5: Structural Sketcher A Tool for Supporting Architects in Early Design Slava Pranovich Technische Universiteit Eindhoven Dept. Math. and Computer Science.

Requirements

• Design elements suitable for early design

• Fast and efficient

• Short learning time

• Fun to use

Graphic Units

A well defined form of graphic representation is a graphic unit (H.Achten, 1998)

•Grid

•Contour•Axial system

•Etc.

•Zone

Geometry Engine

• Design = Graphic Units + Relations• Propagation of geometrical transformations• Properties for graphic units and relations• The KITE manipulator

User interface

Depth + layout geometry = relations

Conclusions

• The use of graphic units is natural for architects• Geometry engine provides the flexibility in

exploring design variants• User interface simplifies the use of the system

such it can be used in early design• The KITE manipulator provides fast geometry
