中文摘要：

针对加热炉钢结构在二维设计过程中存在投影关系复杂,难以表达空间结构的问题,以三维技术为核心,通过Visual Basic对Solid Edge进行二次开发.基于Active X Automation技术,采用先绘制布局再添加材料的处理方式,依照模块化设计思想,将整个钢结构分解为多个子结构.使用先独立生成再装配的自底向上设计模式,开发了交互式绘图程序,界面友好,使用方便,实现了Solid Edge环境下的三维参数化设计.有效地提高了设计效率和质量.并根据工程图纸进行实例设计,验证了所提方法的可行性和适用性.

英文摘要：

It’s hard to express the spatial structure in the 2-D design of steel structure of a heating furnace because of the complex projective relationships.A new way is proposed taking the 3-D technology as a core to redevelop the Solid Edge with Visual Basic,based on the ActiveX automation technology.Drawing a layout diagram as frame then filling the materials is used as design mode.The steel structure is divided into several sub-systems according to the concept of modularization.With the bottom-up pattern in design,every member is designed independently first then assembled together with each other to develop an interactive drawing software which has friendly user interface and is easy to use.In this way a 3-D parametric design system is implemented in Solid Edge environment,thus improving the design efficiency and quality.A design of engineering drawing is given as example to verify the feasibility and applicability of the method proposed.
