CAD training for digital product quality: a formative approach with computer‑based adaptable resources for self‑assessment
(Springer, 2021-01-04)
As the engineering and manufacturing sectors transform their processes into those of a digital enterprise, future designers and engineers must be trained to guarantee the quality of
the digital models that are created and ...
Sketch-Based Modeling in Mechanical Engineering Design: Current Status and Opportunities
(Elsevier, 2022-05-08)
Sketch-Based Modeling (SBM) is a field of study that focuses on the automatic creation of 3D models from freehand drawings. Today, two related branches coexist: one aimed at facilitating input for 3D content creation, and ...
Improving Visualization Skills in Engineering Education
(IEEE Computer Society, 2005-09)
This article analyzes the importance of visualization skills in engineering education. It proposes a dual approach based on computer graphics applications using both Web-based graphic applications and a sketch based modeling ...
A method for reconstructing sketched polyhedral shapes with rounds and fillets
(Springer International Publishing AG, Part of Springer Science+Business Media, 2010)
In this paper we present a method for detecting rounds and fillets in
engineering sketches and drawings, and automatically generating a 3D model of
the corresponding object, with rounds and fillets applied. This method ...
Dibujo normalizado
(Universidad Politécnica de Valencia. Servicio de Publicaciones, 1997)
El contenido de este libro está dedicado al estudio de la representación normalizada de la geometría de productos.
A survey on geometrical reconstruction as a core technology to sketch-based modeling
(Elsevier, 2005-12)
In this work, the background and evolution of three-dimensional reconstruction of line drawings during the last 30 years is discussed. A new general taxonomy is proposed to make apparent and discuss the historical evolution ...
Perceiving ribs in single-view wireframe sketches of polyhedral shapes
(© Springer International Publishing, 2012)
As part of a strategy for creating 3D models of engineering objects from sketched input, we attempt to identify design features, geometrical structures within objects with a functional meaning. Our input is a 2D B-Rep ...
Particle Swarm Optimisation Based 3D Reconstruction of Sketched Line Drawings
(IOS Press, 2004)
The purpose of this paper is to demonstrate the application of particle swarm optimisation to line drawings reconstruction. The paper’s new contribution is the application of swarm intelligence in dealing with machine ...
Metrics of human perception of vanishing points in perspective sketches
(Oliviera, Manuel M.; Skala, Václav© Václav Skala - UNION Agency, 2013)
This paper describes an experiment aimed at discovering how humans perceive vanishing points depicted in perspective sketches of engineering shapes. The goal is to find criteria and metrics for an algorithmic approach to ...
Integrated modeling with Top-Down approach in subsidiary industries
(Elsevier, 2004-01)
This article considers how conceptual design of industrial products is supported by current CAD systems. The case of subsidiary industries, or first tier suppliers, that must simultaneously deal with different customers ...
