| Abstract |
In the teaching field, the existence of automated procedures that allow self-assessment or self-correction of exercises or exams is a great help. Most web learning applications generate tests with single, multiple, or text answers, or the use of closed-solution problems where only the student’s final answer is validated. The complexity increases when we try to score a text, but the most difficult evaluation is in the field of Graphic Engineering, inside CAD/CAM environments. The student assessment usually uses the revision of a digital file with a solution. While it is true that some software may offer tools to compare files, these are focused on the search for differences in their own versioning. When the 3D industrial model is created by students, the tools, planes or geometric sketches are very varied, and an automated assessment is not a simple task. This paper attempts to offer a possible way for the automated correction of the 3D modelling in industrial parts based on some parameters proposed. A programme, called CPIT (Corrector of Three-Dimensional Industrial Parts), has been designed to evaluate the similarity between parts within the CATIA® V5R19 environment using Visual Basic for Applications (VBA). This first version has been tested successfully with several exercises and it is necessary to improve some aspects of it, such as its performance in complex pieces or Boolean operation. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. |
