Abstract

The invention is applicable to computer aided instruction for engineering drawing. According to different users, the method decomposes relevant functions into different module units including management module based on network, kernel module for judging credit based on detailed analyzing knowledge points, module for students to submit homework, module for completing homework and querying feed back, and networked module for managing titles of engineering drawing. Under specific requirement, the system can implement specific rules for judging credits, possessing better flexibility. According to presetting rules, the method can mark highlighted tags on error positions in graph. Through colors, linewidth, line type, and text discrition, taking full advantage of graphical display, the invention realizes adding artificial comment automatically.

Description

technical field [0001] The invention relates to a method for computer-aided engineering drawing teaching, which belongs to the technical field of computer automatic evaluation and testing systems. Background technique [0002] There are too many manual intervention links in the existing drawing exercises and evaluation of tests. In the case of paper work, judges need to visually inspect or even use drawing instruments to measure in order to judge the correctness of the work graphics. If computer graphics are used for homework, it is still at the stage of manual review. The method adopted is to manually open the graph, perform manual query, attribute display, etc., or insert the correct answer, perform comparison, and give a score. Obviously, there are uncertainties in the accuracy of visual inspection and the correctness of detailed attributes. Furthermore, if appropriate comments are to be given, the workload is enormous. Obviously, there are defects such as low efficie...
