本次毕业设计的任务是用VB开发交互式CAD系统的图形编辑部分。VB采用了面向对象编程, 为开发交互式系统提供了一系列的属性、方法和控件设计。交互式CAD系统是计算机绘图系统中比较先进和完善的一种系统形式,是计算机图形最自然的方式之一。具有交互绘图的功能。能实现鼠标绘图、图元选择和编辑,对选中的图元进行修改、几何变换和删除等操作具备图形输出功能。交互式CAD系统的特点是方便、直观、高效。本次设计的重点是图形编辑中的图形的平移和旋转。交互式cad系统在办公、绘图平面设计、工业设计等方面都有很多应用。

Abstract [资料来源:http://www.THINK58.com]

This graduation project duty is develops the interactive CAD system with VB the graphic editor part. VB has used the object-oriented programming, In order to develop the interactive system to provide a series of attributes, the method and to control a design. The interactive CAD system is in the computer cartography system quite advanced and the perfect one kind of system form is the computer corresponds one of most natural ways. Has the alternately cartography the function. Can realize the mouse cartography, a chart Yuan choice and the edition, to the chart Yuan which selects carries on operation and so on revision, geometry transformation and deletion has the graphical output function. The interactive CAD system characteristic is convenient, direct viewing, is highly effective. This design key point is in the graphic editor graph translation and revolves. The interactive cad system in aspect and so on work, cartography plane design, industrial design all has very applies. [版权所有:http://think58.com]
