Using 3D Parametric (Autodesk Inventor®) and 2D Geometric CAD Software (AutoCAD®) in a Design Engineering Course

Abstract

AbstractThe students of Industrial Design Engineering and Product Development degree at Jaume I University (UJI) in Castelló (Spain) receive an integrated training in Technical Drawing and Computer Aided Design (CAD). Learning starts from graphic representation techniques knowledge to a progressive introduction of 2D CAD and 3D CAD. Recently the degree has been adapted to a new curriculum considering that future industrial designers must master 3D modelling CAD to produce quality 3D models, without overlooking the fact that they must also obtain standardization knowledge and skills in 2D drawing. Thus, students should acquire modelling skills at an early stage of their training. This work describes the experience carried out in CADI subject, previously devoted to learning 2D technical drawings with an anecdotal introduction of 3D modelling. During first semester of 2021/2022 course, important changes have been performed so that not only geometric software but also parametric one have been used, introducing 3D modelling of simple parts, without losing sight of obtaining accurate 2D technical drawings, either drawing directly with the 2D software or obtaining views from the 3D model and finishing the technical drawing with the 2D software to be properly standardized. Students value the use of both software and the learning material provided. The experience has been positive, allowing not only the obtaining of proper technical drawings, but also the introduction of parametric models design. Some little changes will be performed in future for a better learning of quality 3D models allowing reusability.KeywordsTechnical drawingsComputer aided designCAD software3D CAD modelling
