建筑结构CAD数据交换技术研究

DATA EXCHANGES OF CAD SYSTEMS FOR BUILDING STRUCTURES

随着CAD技术的发展,CAD在建筑工程领域的应用越来越广泛。本文在分析国内建筑结构CAD应用现状的基础上,对结构CAD如何有效地利用建筑CAD的设计成果作了深入研究,提出了基于构件识别和工程数据库管理的建筑与结构CAD之间进行数据交换的技术。

Based on the analysis of the current available CAD systems, this paper presents a data exchange technology of variable CAD systems for building structures. Recognizing components in a building plan is the main solution of obtaining data items from architectural drawings to derive the associate attribute data for the structural design systems. A feature-based approach is employed in the realization of recognization process. The recognized components are refined automatically by the system and are further modified by the user interactively. Algorithms of refinements are presented in the paper.
