摘要
相贯线作图是工程图学教学中的难点内容,其主要原因是学习者对相贯线的形状缺乏正确认识。研究利用Auto CAD三维实体模型构建相贯体及其相贯线的三维立体图,然后将其转换为二维投影图,既快又准确地画出相贯线的三视图。
This article studied has constructed using the AutoCAD three dimensional full - scale mockup passes through the body the three dimensional block diagram, Then transforms it into the two - dimensional projection, Both and accurately the picture shows off quickly the transversal thee views. This method all has the vital significance to the product modelling design and the project charting teaching.
