摘　　要：利用先进的开发平台开发自己的优势产品是当前软件行业的一个重要趋势。本文讨论了ＡＲＸ（ＡｕｔｏＣＡＤｒｕｎｔｉｍｅｅｘｔｅｎｓｉｏｎ）开发平台的原理与主要功能，类比说明了ＡＲＸ优于Ａｕ－ｔｏＬＩＳＰ和ＡＤＳ的深层原因，简要介绍了ＡＲＸ的类库集及其提供运行时类型描述机制，讨论了ＡＲＸ与ＭＦＣ混合编程的优势及实现方法。文章阐述了基于ＡＲＸ开发平台开发的曲面造型系统ＳｕｐｅｒＳｕｒｆ的主要数学方法，具有组合曲线功能的ＳｕｐｅｒＣｕｒｖｅ三维曲线子系统的关键问题以及面向对象的裁剪ＮＵＲＢＳ曲面体系结构。该系统与ＡｕｔｏＣＡＤ无缝集成，可用于构造具有复杂构型规律的零件表面和模具型腔。最后，文章给出了ＳｕｐｅｒＳｕｒｆ曲面造型系统的主要功能。The trend to develop applications based on advanced software platforms has been shown. The principal and main functions of ARX(AutoCAD runtime extension) are introduced. The reason that ARX is superior to AutoLISP and ADS is shown by comparison. Brief description of ARX classes library and the runtime type discription mechanics are included. The method and priority of programming with ARX and MFC are discussed. Furthermore,SuperSurf surface modeling system, which is based on ARX, is introduced. The mathematical foundation of SuperSurf,SuperCurve subsystem and objectoriented trimmed NURBS surface structure are researched in detail.Finally, the major functions of SuperSurf are introduced.
