We discuss the importance of visualization skills in engineering education and propose a dual approach to helping students improve their spatial abilities. The approach is based on computer graphics applications, and uses both Web-based graphics applications and a sketch-based modeling, system. By combining these approaches, we can capture students'(More)
This paper presents a novel application of Augmented Reality for improving spatial abilities of engineering students. An augment book has been designed to provide 3D virtual models that help students to perform visualization tasks to promote the development of their spatial ability. A validation study with 24 freshmen on Mechanical Engineering at University(More)
In this work, the background and evolution of three-dimensional reconstruction of line drawing over the last thirty years is discussed. A new general taxonomy is proposed to describe and discuss the historical evolution of geometrical reconstruction and its challenges. The evolution of geometrical reconstruction from recovering know-how stored in(More)
roduct development is a key activity for enterprise survival and competitiveness. This process must be agile and efficient to provide enough flexibility to adapt to a changing market. Most new product development methods focus on the design and shorten the development cycle. Digital tools like computer aided design, engineering, and manufacturing (CAX) and(More)
This paper presents some learning support tools for developing spatial abilities in engineering design students. They are based on the previous authors' experience in teaching traditional Engineering Graphics and uses both on-line and batch computer-aided generation of 3D models from 2D freehand sketches. Although these applications can be used with(More)
