To ensure an efficient operation of the integrated teaching method for Mechanical Drawing and Computer Plotting course, this paper, based on research and analysis, establishes the method’s guiding principles, analyzes the pedagogic design of teaching materials in the method from six aspects, and draws attention to problems with its operation. Based on a consensus reached as to the question "why adopt the integrated teaching method", we strive to answer the question "how to implement the integrated teaching method", i.e., how to integrate teaching materials of computer plotting with the teaching materials of mechanical drawing to achieve the results of "the integrated whole is larger than the sum of its parts".
