机械制图中相贯线的求解研究

通常求解相贯线的投影是利用投影的集聚性或运用辅助平面及球面几种方法进行,求解过程比较复杂。运用编程技术来实现实体相贯线作图的过程,使用方便,但需要编程基础。通过制作三维模型,利用自动生成工程投影,构建了相贯线投影图。最后对几种求解的优势进行分析,为机械制图中相贯线教学提供参考。

Solving the projection of intersection line is usually by use of Clustering of projection or the use of auxiliary plane and spherical several methods, so the process is more complicated. It is easy to realize the process of intersection line drawing by using programming techniques, but it requires programming. By making a 3D model, the projection of the intersecting line is constructed by using the projection of the project. Finally, this paper analyzes the advantages of several solutions, providing reference for the teaching of mechanical drawing.
