Abstract: To solve the inconsistency between short periods and excessive teaching contents, an
integration teaching method of simplifying teaching contents and emphasizing practical operation
synchronously is proposed. The functions and characteristics of domestic and overseas 2D drawing
softwares are studied synthetically. On the premise of satisfying the configuration request of software
and hardware, the teaching software ought to be characteristic of wide application, easy adaptation
and friendly operation interface so on. In addition, the view that teaching software should embody the
advanced idea of design thinking separating from expression format. The teaching practice shows that
the CAD teaching method taking operation ability as goal can conform to the requirements of periods
and abilities. And the knowledge field of students can be spread.

Key words: mechanical drawing, CAD teaching, domestic CAD software, integration teaching
