基于AutoCAD的参数化CAD系统的接口技术

The Interface Technology of the Parametric CAD System Based on AutoCAD

工程设计中 ,基于 Auto CAD进行二次开发参数化 CAD系统得到了广泛的应用。对 R14版的 Auto CAD进行二次开发的常用方法是 ARX(Auto CAD Runtime Extension)法。利用此方法开发的应用程序与 Auto CAD的接口方式不同 ,直接影响着整个系统的实用性和用户界面的友好性。本文论述了应用程序与 Auto CAD接口的几种技术 ,并介绍了实现方法。

Parametric CAD system, based on AutoCAD, has been widely applied in the customized application development in engineering design. ARX (AutoCAD Runtime Extension) is the common method in such a further developments for AutoCAD about R14, and the application programs developed in ARX have different interfaces from AutoCAD, which directly affect the practicability and user friendliness on the whole systems. The paper discusses some kinds of interface technologies between application program and AutoCAD,also introduces the implementing methods.
