title Development of an Expert Cad System for Visual Design of a Bridge in a Landscape

summary Architects, landscape architects and urban designers are often required to be involved in the process of bridge design from an aesthetic point of view. The authors have been developing a comprehensive CAD system to support such visual design works, especially at an early stage of design. Conventional complicated technical standards and guidelines tend to discourage creative design. In order to support free conception and creation of bridge forms, this system includes a visual design core system as a workshop, even enabling freehand sketch drawing on existing landscape images of the site. This is supported by a landscape simulation subsystem. The system can also provide initial design ideas with several different types of bridge form, derived from knowledge based subsystems on design guidelines and precedent examples which can be quoted also to examine the physical possibility of sketch drawn alternatives in terms of structural dimensions and construction costs. Created design alternatives will be analyzed by a visual impact analysis subsystem to assess their influences on surrounding environments from a visual geometri-cal standpoint. This system is intended to enable architects, landscape architects or urban designers to create and examine design alternatives on a real-time basis.
