面向定制的工程CAD系统模板技术

工程CAD可以通过提供定制功能以满足日益增长的个性化需求，并适应不同企业，行业的标准和惯例，文中在以往模板技术研究的基础上，借鉴面向规模定制设计的方法，设计了面向定制的模板技术实施方案，（1）参照功能需求的分解树，面向多个用户需求提炼功能模式；（2）建立工程信息的多层结构，分析应模块；（3）为特定模块设计多视图的模板，保联工程CAD的可定制，可复用以及定制对象同系统的无缝集成，最后介绍了PDSOFT系列中的模板技术应用。

Customization Oriented Template Technology for Engineering CAD System

AEC CAD should provide the capability of customization to meet the increasing needs of diversified projects and adapt to various kinds of standards and routines applied in different industries and enterprises. Based on the various concepts of templates being promoted and applied in recent years, the paper brings forward a schema for implementing customization oriented template technology: (1) Referring to the functional requirements decomposition tree, functional patterns addressing the requirements of multiple users are extracted. (2) An hierarchy of multi level engineering information system to facilitate the analysis of corresponding modules is constructed. (3) Multi view templates are worked out for each kind of particular modules so as to realize seamless integration of customized objects with the system as well as to ensure the capability of customization and reuse of AEC CAD. At last, the application of template technology to various software products of PDSOFT is introduced.
