模仿CAD绘图软件，可绘3D图形。主要解决了VB处理矢量图的问题，而且可生成3D预览图。很完整的源代码. -imitate CAD software, 3D graphics can be drawn. VB mainly to solve the problem of vector processing, but also generate 3 D preview map. Very integrity of the source code.

在VB环境中操作三维模型的实现方法 针对VC在开发虚拟设计和三维仿真程序中的不足，提出了基于VB环境开发三维仿真程序的可行性，并对其中关键的三维模型的显示、操作等技术性问题给出了具体的解决方法。-In VB operation method of 3d model In the development of virtual design in VC and 3d simulation program is proposed based on the 3d simulation progr
