支持设计重用的建筑工程图三维信息建模

3D Model of Building Engineering Drawings for Design Reusing

本研究统计了建筑工程图中标准层间重复内容的重用潜力,分析了重复性特点,提出了基于三维信息建模的重复性模型。该模型对重复内容的竖向和横向分布规律进行建模,采用"块-引用"机制作为重用部件和实施重用的载体和工具,对原本扁平化的工程图设计信息进行了重新组织。重构后的设计信息集合成为一个反映重用规律的有机整体,不仅充分避免了复本图元的存在,实现了联动修改,大大减少了绘制和修改工作量,还为自动打印等更深入的自动化功能提供了操作环境,大大提高了设计效率。

By investigating the characteristic of information repeating in building engineering drawings,a 3d design reusing model is developed to exploit the potentialities.The model has the capacity to deal with the vertical repeating and the horizontal repeating.It helps the flat original data in drawings be reorganized into a multi-level tree structure.Each reusable part finds its place in the leaves and is deployed automatically to where it should reappear through the branches in the tree.Software system based on the model employs the＂block-reference＂function in AutoCAD to store the reusable parts and implement the assemblying action.It helps to save all the copies for the repeating information to achieve the synchronous modification.More advanced functions such as automatical printing for standard floors have been involved in the system.The statistic on practice shows that it can enhance the efficiency by more than 50%.
