The course is aimed to let students understand basic knowledge of the engineering drawing. In addition,students can use the rules for lines and letters to describe the shape. We make use of theory of projective geometries to draw the engineering drawing for mechanical parts. Finally, Students are expected to be capable to read and to make engineering drawings through the learning and practice. The contents include: CNS standards, applied geometric drawings, orthographic views, dimensions and notes, auxiliary views, sectional views, tolerance and fits, surface roughness。
