“…3D modeling and technical drawing serve as integral components in engineering, providing the means to conceptualize and communicate complex designs and structures visually. The study by Merzdorf et al introduces the Object Assembly Sketching test, a new assessment tool for evaluating sketching skills in engineering through object assembly tasks, highlighting the importance of sketching for spatial abilities [27]. The paper by Li explores the integration of art education in engineering graphics teaching as a means to cultivate interdisciplinary talents, enhance artistic literacy, promote learning of projection theory and mapping knowledge, and proposes a systematic integration method of visual thinking and creative thinking, contributing to innovative education in engineering graphics [28].…”

Integrating low-cost fused filament fabrication 3D printing as a foundation for learning 3D modelling is explored. This method blends traditional computer aided design (CAD) instruction with additive manufacturing possibilities. Experimental results demonstrate increased comprehension speed and reduced learning time. This hands-on approach empowers students by enabling direct engagement with the modelling process. Analogous to reverse engineering, the strategy instructs engineering students from final product to model creation, closing the gap between theory and practice. Incorporating 3D printing bridges this divide, enhancing understanding, creativity and problem-solving. The study underscores technology's influence on learning strategies, aligning with the surge of 3D printing in education. Results link advanced design technology usage to improved student performance, with 3D-printed materials yielding 45% higher grades and 30% faster task completion. This study advocates curricular advancement for design-focused careers through enhanced technology integration and favourable 3D printing model reception.

“…A sketch is said to improve spatial abilities (Chester 2007;Delahunty, et al, 2012;Merzdorf 2022). Subsequently, EGD provides learners with an opportunity to learn how to identify and solve design problems using critical and creative thinking when applied to civil, electrical, and mechanical drawings.…”

In Technology, learners are introduced to draw both technical and artistic graphics, in addition to skills such as investigation, design, making, evaluation and presentation. These skills should be gradually improved each term. However, it has been observed that teaching graphics remains a challenge for many high school technical teachers and pre-service teachers in higher education institutions. A major focus of engineering graphics and design education is on drawing-based communication, such as technical drawings. Technical drawing is considered a universal language understood by technicians and engineers around the world. The aim of the study was therefore to investigate the experience of teachers teaching graphics in technical high school classrooms, particularly in the Senior Phase Technology classrooms. The study was a case of a semi-rural school involving a Technology teacher with experience in teaching Technology and graphics. Qualitative was-structured interviews and non-participant observation were used, and inductive content analysis was used for data analysis. The results showed that although the teacher understood very basic concepts of graphics, the use of demonstration aids graphics teaching. Furthermore, the results showed that procuring resources for successful graphics teaching is a challenging factor. This article then concludes that constructivist theory has potential towards the teaching of graphics.

“…Informed by a systematic literature review and expert consultation, we developed an Object Assembly Sketching skills test to benefit engineering educators in teaching and assessing perspective sketching skills through spatial reasoning exercises [13]. The test asked students to assemble 3-dimensional shapes using mental imagery and mental rotation, and to sketch assembled objects in 1-and 2-point perspective.…”

“…Sketches were graded on representation accuracy, precision, scale, proportion, converging lines, line smoothness, and line weight. We conducted a pre-post intervention study of sketching skills improvement in two sections of an engineering graphics course, with approximately 45 students in each section, across two semesters [13]. Students completed the test before and after four weeks of sketching instruction and practicing with SketchTivity.…”
