组合体的读图与画图在工程制图课程中是重点和难点，正确理解投影面垂直面的“类似形”投影是关键。文中作者提出用“点线面分析法”来求解“类似形”。综合应用“点线面分析法”和“形体分析法”，能够帮助学生识读和绘制组合体，并提升学生的空间想象能力。

The drawing and reading ability of the complex are the most important part in the course of the engineering drawing. Un-derstanding the characteristics of oblique surface's projection is the key. A dot-line-surface analysis method has been proposed to draw the similar projection of the true shape. The synthetic ap-plication of dot-line-surface analysis method and shape analysis method can help student to read and draw the complex, and can help them to establish the corresponding relationship between plane drawing and spatial shape.
