针对AutoCAD建筑图纸山图时的一些实际问题,开发了一个基于AutoCAD平台的图纸输山应用程序系统,系统设计主要包括菜单程序设计、对话框界面设计和功能实现设计。菜单程序的设计目的在于在AutoCAD界面下直接调用对话框应用程序,而对话框界面设计力求满足用户所需数据的直观查找、相应参数的方便输入和所绘图形的选择,功能实现设计的关键是处理用户操作或者说对话框回调。
Aiming at some practical problems of AutoCAD architectural drawings and maps, a drawing and mountain application system based on AutoCAD platform was developed. The system design mainly includes menu programming, dialog interface design and function realization design. The purpose of the menu program is to call the dialog application directly under the interface of AutoCAD. The design of the dialog interface strives to find the data which the user needs intuitively, and the corresponding parameters are conveniently input and the choices of the drawing are drawn. The key of the function realization design is Handling user actions or dialog callbacks.
