摘　　要：嵌套图形作图是工程制图类课程中比较有技术难度的作图训练项目，单纯借助尺规作图的常规作图方法无法实现，必须进行一定的分析研究和方法设计。通过建立绘图参数（包括定形参数与定位参数）与已知参数之间的关系，对某嵌套图形进行了作图方法与步骤的探索和设计。其分析和设计过程另辟蹊径，对该类图形的尺规作图规律和作图方法研究具有重要的借鉴和参考意义。Nested graphic drawing is a difficult drawing training item in engineering drawing courses. It is impossible to draw a nested graphic simple by the normal and conventional drawing method. Some analysis and method design must be carried out in drawing nested graphics. In this paper, the connection between drawing parameters （including setting parameters and positioning parameters） and known parameters is established, and the drawing methods and steps of a nested graphics are explored and designed. The new geometric drawing method for a nested drawing has important and significant reference for the study of the rules of drawing and drawing method of this kind of graph.
