Application of BIM technology in post-process system of CAD software for rural residence structures
CHANG Zhiguo;School of Civil Engineering,Tongji University;Shanghai Tonglei Civil Engineering Technology Co. ,Ltd.;
Based on BIM technology,a post-processing system of CAD software is developed for various forms of rural residence structures. According to the object-oriented programming theory,a series of intelligent objects are abstracted which can describe the geometry information,structure properties and design conditions of the parts in real structures. The complex spatial relationships and construction details can be shown directly,accurately and completely by 3D solid modeling. Therefore,on the basis of the solid model, the specified entities can be selected to extract the geometry information, and the construction drawings and processing drawings can be completed by the projection and its elimination and automatic labeling. In the software system,the manufacture information of components and parts can be extracted from 3D solid model,which can be output in the data formats required by CNC device,including the binary data,Excel,etc.
