基于三维实体模型的钢结构工业厂房CAD/CAM软件后处理系统

为提高钢结构工业厂房设计的准确性、精确度和工作效率,为某钢结构工业厂房CAD/CAM软件研制出基于三维实体模型的后处理系统.该系统基于面向对象的编程技术,抽象出描述实际结构零件几何信息、结构特征和设计条件的智能型实体对象.将对象以及对象之间的层次关系和逻辑关系存储在AutoCAD图形数据库中,形成三维实体模型,用于直观、准确和完整地表现具有复杂空间关系和细部构造的真实结构；实现数据库对象的建立、编辑、查询、显示和数据整理等操作.该系统结合具体结构形式的特点,实现用于施工图设计和深化设计的全部关键功能.

CAD/CAM post-process software of industrial steel structure plant based on 3D solid model

To improve the design correctness,accuracy and efficiency of industrial steel structure plants,the post-process system of a CAD/CAM post-process software is developed on the basis of 3D solid model.Based on the object-oriented programming technology,a series of intelligent solid objects are Abstracted to describe parts with deferent geometric information,structure characteristics and design requirements in real structures.The objects and their hierarchy and logic relations are stored into AutoCAD graphics database to construct a 3D solid model,which can visually,accurately and completely present the real structures with complex spatial relations and detail parts.The operations on the database objects such as creating,editing,querying,rendering,data processing and so on are implemented.All the key functions on construction drawing design and deep design are implemented for the post-process system by combining with the characteristics of concrete structures.
