摘　　要：针对工程制图中截交线虚拟实验中的柱、锥截切的特点，确定了模型的点、边、面形式的数据结构，并定义了模型数据类；通过比较判断平面与线段相交的算法和判断平面与立体相交的算法，确定了将其转换为平面与线段相交求解的新算法，并以此算法为理论基础，研究开发了此类实验的系列应用程序。在实际应用中，该虚拟实验的反应速度和适时显示的流畅性得以显著提高，为进一步提高工程图学虚拟实验的实用性提供了技术支持。For the virtual experiment of cutting cylinders and cones used on cutting plane , this paper analyzes the experiment, confirms the model structure of point-edge-plane based on the computer graphics , and defines data class of model. And the arithmetic for estimate intersection of plane and line and intersection of plane and solid is compared, the arithmetic for the experiment is built, and the formula of calculation point of intersection is acquired. And based on the formula, application of this kind experiment is designed. In use, the reaponse rapidity and fluqency grade of this virtual experiment are improved obviously. And the foundation for improving practicability on virtual experiment of engineering graphics is provided.
