Computer-aided Marking Sleeve Parts Diagram Operating Software Development

For the purpose of practical need of instruction in Descriptive Geometry and Mechanical Drawing, This paper researched and developed a set of CAl courseware, which to correct works of shaft and sleeve parts drawing. The intention of the courseware is to extricate the teacher from the repeat and overmuch workload during the correction works, to attract students? interesting of study, to raise efficiency. This courseware takes the ObjectARX as the secondary development tool, takes AutoCAD2000 project drawing system as the development basis of the software and applies the OOP technique to the software. This paper briefly introduces the current research situation of the correct works?software, the features of ObjectARX as the secondary development tool, stresses on the discussion structure and function realization of the three module──Interjecting to Drawing Software Module, Compare Parts Drawing Works Module and Result Display Module. The correct works?software checks up assignment automatically and displays the correct results. It also gives the advice on assignment and student's score and so on. These all achieve the goal of computer-aided instruction and make the courseware have well used. This courseware will take a certain aided function on lightening the teacher's labor intensity and improving the effect of instruction.
