摘要
为开发建筑信息模型(Building Information Modeling,BIM)软件,阐述BIM的技术特点,选用ObjectARX技术在AutoCAD平台上进行二次开发,开发轻钢厂房结构BIM软件.该软件直接读入包括SAP和ANSYS等软件的结构模型,根据用户选择的节点类型和设计规范自动完成构件和节点的设计,并进行钢结构三维实体信息模型的拼装;在此基础上,采用分解、分层和组合的方法组织节点的数据结构,实现钢结构节点的全自动交互式设计、编辑及复核,设计结果的图形与文本查询等功能;直接生成供工厂使用的各个零件的制作翻样图、材料表以及结构体系造价等信息;该软件还实现三维实体模型到ERP软件的输出接口.
To develop the Building Information Modeling（BIM） software, the technical characteristics of BIM is introduced, and the BIM software of light steel mill building structure is developed by the secondary development technology using ObjectARX in AutoCAD. In the software, the structure model such as SAP, ANSYS, and so on can be read directly, the member and joint design can be automatically implemented according to the chosen joint type and design specification, and the 3D solid information model can be assembled. So the data structure of steel joints can be organized by disassembly, layering and reassembling, the automatic interactive design edit and check of the joints of steel structure, and the graphic and text query functions can be implemented. The processing map, material list, project cost, and so on can be generated for users. The exportation interface of 3D solid information model for ERP software is also realized.
