TWO-DIMENSIONAL TEACHING IN 3-D MECHANICAL DRAWING

摘要

The contents of the book 3-D mechanical engineering are introduced briefly in this paper. And then it is described in detail that how to enhance the 2-D application ability while teaching 3-D mechanical drawing, especially about the theory of the projection view as well as the transformation between 3-D space structure and 2-D plane view. In the teaching process, 3-D animation can be used to help student to understand the projection theory and the transformation process thoroughly. A new method called 4-D Space Cinema Teaching is proposed. Finally, the teaching results during these two years are summarized.
