Abstract: In the field of CAD teaching, there have been many innovative teaching methodologies and
software to help students understand abstract principle, complicated assemble procedures and forms,
and students draw a complex engineering drawing easier. But until now, CAD drawing exercises of
students do not much ground-breaking change. Teachers do not have enough time to carefully track
every drawing steps and methods, and there is no possibility to correct their problems. An interactive
CAD drawing experiment platform is developed. The interactive platform, on the one hand through
the system automatically stores the student in the process of drawing the progress, so that teachers can
understand the student's practice, and then provide a recommendation. And on the interaction between
students and teachers, will also encourage cooperation between the students together to complete
complex projects.
