面向产品结构设计的图形置换技术

A Graphics Substitution Approach to Product Structural Design

在产品结构设计的概念设计阶段，具有一定工程意义的图形单元是工程师实现设计思想图形化的工程语言。本文以图形单元作为产品结构建模的基本单位，提出了进行产品结构模型编辑的图形置换技术，给出了实用、方便的单元操作方法，实现了基于功能设计图形结构的过程。

During the conceptual phase in product structural design, the graph modular with specific engineering semantics is a powerful expressive tool for engineers to convert design intent to drawing. Using the graph modular as the basic cell of product structure modelling, we put forward a graphics substitution approach to edit the structure model, and present a set of useful methods to operate the graph modular. The maping procedure from function to structure is realized.
