Computerized System and Method for Automated Computer Grading of CAD 2D and 3D Geometry Assignments

摘要

A computerized system, method, and code to automatically assess the correctness of a user's solution to a computer-aided design (CAD) 2D and 3D assignment, comprising: an instructor creating and storing in a memory of testing computer system a probing data set; submitting to the testing computer from user's computer system via a network a user's solution to a CAD assignment; assessing the correctness of the user's solution by the testing computer processor using the probing point set; and, transmitting to, and displaying on the user's computer system whether the solution is correct. If the solution is not correct, then the user may immediately re-compute and re-submit their solution to the testing computer system. Correctness is determined by the testing computer system conducting tests on the user's solution as compared to the instructor's solution, comprising one or more of a size test, position test, inclusion test and complement test.

主权项

1. A computerized method to automatically assess the correctness of a user's solution G to a computer-aided design (CAD) assignment, comprising:
a. computing and storing in a testing server's memory a probing data selected by the instructor or creator of the CAD assignment; b. receiving a user's solution to the CAD assignment by the testing server; c. assessing the correctness of the user's solution by a processor(s) of the testing server; d. displaying by the testing server whether the solution is correct; and, e. wherein if the user's solution is not correct, then it may be corrected and re-submitted by the user, and re-assessed for correctness by the testing server.
