Spatial visualization ability is an important factor in a child's cognitive development. Its development is affected by numerous factors such as general intelligence, problem-solving skills, gender, playing building games, experience with engineering drawing and 3D modelling, etc. The study aimed to explore how engineering 3D modelling with…

An ever-increasing array of design visualisation tools are available to designers. As such, design education is constantly challenged to keep up with these trends so that students are best equipped for entering industrial practice. This paper reports a study into the use of digital sketching, a relatively new digital visualisation tool. The study…

The purpose of the study was to explore the effects of augmented reality (AR) in an introductory engineering graphics course. The study specifically examined the potential for AR to affect the spatial visualization ability of students and influence student motivation. This study included 50 students from an introductory engineering graphics course…

The definition of visualization in engineering graphics has evolved over the years due in part to extensive research in visualization by the engineering design graphics profession. The literature indicates research in the areas of engineering graphics and the use of visualization has grown from improvement of visualization skills and the…

This review paper presents a systematic literature review on the use of Augmented Reality (AR) in engineering education, and specifically in student's spatial ability training, for the last decade. Researchers have explored the benefits of AR, and its application has been of increasing interest in all levels of education. Engineering students tend…

For the last decade, remedial spatial visualization training has been offered to first-year engineering students in traditional classroom settings where students attend class and interact face-to-face with an instructor and peers. An alternative to the traditional pedagogical approach is a multi-modal blended learning format that combines in-class…

The purpose of this study was to determine the influence of computer-aided design (CAD) software-based instruction on the spatial visualisation skills of freshman engineering students in a computer-aided engineering drawing course. A quasi-experimental design was applied, using the Purdue Spatial Visualization Test-Visualization of Rotations…

Many articles have been published on the use of 3D printing technology. From prefabricated homes and outdoor structures to human organs, 3D printing technology has found a niche in many fields, but especially education. With the introduction of AutoCAD technical drawing programs and now 3D printing, learners can use 3D printed models to develop…

Industrial Designers need to understand and command a number of modelling techniques to communicate their ideas to themselves and others. Verbal explanations, sketches, engineering drawings, computer aided design (CAD) models and physical prototypes are the most commonly used communication techniques. Within design, unlike some disciplines,…

Spatial abilities have been used as a predictor of success in several engineering and technology disciplines (Strong & Smith, 2001). In engineering graphics courses, scores on spatial tests have also been used to predict success (Adanez & Velasco, 2002; Leopold, Gorska, & Sorby, 2001). Other studies have shown that some type of…

Engineering graphics has historically been viewed as a challenging course to teach as students struggle to grasp and understand the fundamental concepts and then to master their proper application. The emergence of stable, fast, affordable 3D parametric modeling platforms such as CATIA, Pro-E, and AutoCAD while providing several pedagogical…

The purpose of this study is to determine which 3D viewers should be used for the display of interactive graphic engineering documents, so that the visualization and manipulation of 3D models provide useful support to students of industrial engineering (mechanical, organizational, electronic engineering, etc). The technical features of 26 3D…

Spatial visualization is a fundamental skill in technical graphics and engineering designs. From conventional multiview drawing to modern solid modeling using computer-aided design, visualization skills have always been essential for representing three-dimensional objects and assemblies. Researchers have developed various types of tests to measure…

This dissertation presents information gathered and analyzed through an electronic internet-based Delphi Survey process. The purpose of this study is to identify a consensus of factors that might forecast the future effects of Rapid Prototyping (RP) technology on engineering design education when used for the purpose of overcoming the limitations…

A control group of 17 engineering students produced 2- and 3-dimensional shapes with manual drafting tools; an experimental group of 12 used computer-assisted drafting. From pre/posttest data, it appeared that computer models were no better at improving spatial visualization or orthographic projection skills. (SK)
