This paper aims to analyse to what extent the engineering curricula contribute to the development of visual literacy among engineering students. Communicating and thinking visually is a basic skill for all engineers, being a fundamental part of their educational stage. For this purpose, Engineering Graphics subjects from 30 engineering schools…

Engineering drawing is valuable in capturing geometric features, conveying engineering ideas, and creating a blueprint of the intended product. Engineering students usually perform orthographic projections, imagining a 3D situation and sketching its 2D representation. That requires imagination and mental visualization, determined by the learner's…

Over several years, first-year pre-service education students regularly experienced difficulty with engineering graphics activities. Research has already established that these activities require the use of well-developed spatial visualisation which is, for the most part, determined by a persons' spatial experience. The importance of this study…

The purpose of this study is to investigate student designers' attitude and choices towards the use of computers and paper sketches when involved in a graphic design process. 65 computer graphic technology undergraduates participated in this research. A mixed method study with survey and in-depth interviews was applied to answer the research…

This paper discusses the formulation of educational outcomes for engineering graphics that span the global enterprise. Results of two repeated faculty surveys indicate that new computer graphics tools and techniques are now the preferred mode of engineering graphical communication. Specifically, 3-D computer modeling, assembly modeling, and model…

Computer graphics systems typically produce a single, machine-like character font. At most, these systems enable the user to (1) alter the aspect ratio (height-to-width ratio) of the characters, (2) specify a transformation matrix to slant the characters, and (3) define a virtual pen table to change the lineweight of the plotted characters.…

A treatment group of technical-graphics students who were taught drafting principles using an interactive multimedia device to enhance instructor presentation of the material scored significantly higher, retained more, and had better attitudes than controls. There were no differences in amount of instructional time, but considerably more…

A study was conducted to determine the effectiveness of teaching multiview and pictorial drawing using traditional methods and using computer-aided drafting (CAD). Research used a quasi-experimental design; subjects were 37 full- and part-time undergraduate students in industrial technology or technology education courses. The students were…

Many of the costs of design, construction, and building operation derive from the reliance on drawings as the description of record of the building. As a replacement, this paper outlines the design of a computer system useful for storing and manipulating design information at a detail allowing design, construction, and operational analysis. A…

It is generally accepted that the ability to visualize is an important tool for engineers and technologists especially in engineering graphics. Enhancing the spatial visualization abilities of engineering students has long been a focus of engineering graphics educators. Over the years a variety of test and procedures have been developed to…

This mini-course and article are presentations from a workshop on computer-aided drafting. The purpose of the mini-course is to assist drafting instructors in updating their occupational knowledge to include computer-aided drafting (CAD). Topics covered in the course include general computer information, the computer in drafting, CAD terminology,…

Development of the Building Description System (BDS) was undertaken to explore use of the computer to construct models of complex physical systems. A fundamental goal of this work is a computer system capable of replacing drawings as the primary description for design and construction of buildings. This paper presents an overview of the database…

Studies whether traditional drafting equipment (TRAD) or computer aided drafting equipment (CAD) is more effective. Proposes that students using only CAD can learn principles of drafting as well as students using only TRAD. Reports no significant difference either on achievement or attitude. (MVL)
