Development and Research of an Automatic Engineering Graphics Marking System

CurrentCAD based on Scalable Vector Graphics (SVG) technology and introduces a number of innovative features in the way of answering graphics examination questions. These include the ability to answer questions in 2D and 3D computer-aided design, as well as automatic correction of assignments online in the Web environment. Additionally, it develops an intelligent engineering graphic marking system. Teachers can log in the system, and build different types of test papers, import test papers, set up evaluating standards, import the students’ information, query the answers and the results of the test papers. Students log in the system, and answer the questions online. CurrentCAD has the functions of auto-evaluation, result analyzing and statistical analysis. On the one hand, this reduces the heavy workload of teachers in correcting homework. On the other hand, students can be free from time and place restrictions, self-testing at any time, and directly understand their own learning situation. Cloud CAD is free of installation and plug-ins, free from the dependence on AutoCAD and other drawing software, thus enabling cross-platform, cross-system and cross-terminal use, online drawing design and intelligent marking functions.
