The Establishment Of The Model Library Of Technology Drawing And The Application And Study Of The Second Exploration

Technology drawing is a subject-specific basic test of the industry science universities and colleges, aims at training the student's drawing ability and the ability of space visionary, space to read engineering drawing, to analyze and solve the problem. The teaching model is playing an important role at positive assisting teaching during the process of helping students to understand content of courses vividly as the important component of means of teaching. But have the problems of two respects in our teaching practice: Object teaching model is carried inconvenient on one hand, and easy to damage, inconvenient on being kept, doing sports and demonstrate that analyze with sports that a lot of defects exist too in object teaching model; On the other hand the using of teaching software of multimedia with three dimensional model and three-dimensional animation can not realize the mutual behavior user, make students' thinking development must be limited, they can't utilize convenience on renewal of knowledge and swift advantage.This text has varied the teaching model of technology drawing, has designed structure and content of the model library, and has set up the entity (parent) of the parameter model on Pro/Engineer platform, has used API interface of Pro/Engineer wildfire, on V C ++ integrated developing platform, have realized management and parameter mutual, regeneration, revealing and revising of model of the model library of making maps to the project.This text employs the teaching model library based on three-dimensional modeling technology where the electronic computer software is set up and parameter regenerated system of model, can not only overcome the defect that the traditional teaching method of technology drawing exists, improve the ability of analyzing and solving the problem, but also that the further studying and improving of this system will exert an influence on technology geometry.
