面向智能CAD的分层构造自动型方法

ICAD-ORIENTED AUTOMATIC MODELLING BASED ON HIERARCHICAL CONSTRUCTION METHOD

本文着重对由抽象符号转化成具体形体的技术作了研究，提出了分层构造的自动造型方法．它支持直接由抽象的设计方案自动生成设计结果的三维表示，因而更适合于以辅助方案设计为核心的智能ＣＡＤ系统．一个基于该自动造型方法的椅子智能ＣＡＤ实验系统已在浙江大学人工智能研究所投入运行．

This paper mainly discusses the technology of transforming abstract symbol into concrete 3D model. A hierarchy-construction automatic modelling method is proposed, it supports transforming abstract design sketch into expected result 3D model, and meet the modelling demand of computer aided sketch design, so it is suitable for intelligent CAD systems. This method has been implemented in an intelligent chair-design system,which is running in Al Institute of Zhejiang University.
