A case study on the use of model quality testing tools for the assessment of MCAD models and drawings
González-Lluch, Carmen; Company, Pedro; Contero, Manuel; Dorribo Camba, Jorge; Colom, Jesús Ahmad Ibrahim (2017-08)In this paper, we build on the idea that specialized instruction improves the overall quality of CAD documents by guiding students into selecting the most suitable modeling strategies and approaches. To this end, automatic ... -
A constraint redundancy elimination strategy to improve design reuse in parametric modeling
González-Lluch, Carmen; Plumed, Raquel; Pérez López, David; Company, Pedro; Contero, Manuel; Dorribo Camba, Jorge Elsevier (2021-08)Strategies for design reuse play a fundamental role in the development of products that change and evolve over time. Design changes often involve modifications in the geometry of parts and assemblies, which are driven by ... -
A fast approach for perceptually-based fitting strokes into elliptical arcs
Company, Pedro; Plumed, Raquel; Varley, Peter Ashley Clifford Springer (2015-04-30)Fitting elliptical arcs to strokes of an input sketch is discussed. We describe an approach which automatically combines existing algorithms to get a balance of speed and precision. For measuring precision, we introduce ... -
A Functional Classification of Text Annotations for Engineering Design
Company, Pedro; Dorribo Camba, Jorge; Patalano, Stanislao; VITOLO, Ferdinando; Lanzotti, Antonio Elsevier (2023-02-04)Describing and supplementing geometric shapes (parts) and layouts (assemblies) with relevant information is key for successful product design communication. 3D annotation tools are widely available in commercial systems, ... -
A method for reconstructing sketched polyhedral shapes with rounds and fillets
Company, Pedro; Varley, Peter Ashley Clifford 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 ... -
A new algorithm for finding faces in wireframes
Varley, Peter Ashley Clifford; Company, Pedro Elsevier (2010)The problem of identifying the topology implied by wireframe drawings of polyhedral objects requires the identification of face loops, loops of edges which correspond to a face in the object the drawing portrays. In this ... -
A quantitative analysis of parametric CAD model complexity and its relationship to perceived modeling complexity
Contero, Manuel; Pérez López, David; Company, Pedro; Camba, Jorge D. Elsevier (2023)Digital product data quality and reusability has been proven a critical aspect of the Model-Based Enterprise to enable the efficient design and redesign of products. The extent to which a history-based parametric CAD ... -
A survey on 3D cad model quality assurance and testing tools
González-Lluch, Carmen; Company, Pedro; Contero, Manuel; Dorribo Camba, Jorge; Plumed, Raquel Elsevier (2017-02)A new taxonomy of issues related to CAD model quality is presented, which distinguishes between explicit and procedural models. For each type of model, morphologic, syntactic, and semantic errors are characterized. The ... -
A survey on geometrical reconstruction as a core technology to sketch-based modeling
Company, Pedro; Piquer, Ana; Contero, Manuel; Naya, Ferran 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 ... -
Activity modelling in a collaborative ceramic tile design chain: an enhanced IDEF0 approach
Romero Subirón, Fernando; Company, Pedro; Agost, Maria-Jesus; Vila, Carlos Springer-Verlag (2008)Explicit descriptions of should-be and to-be activities and processes are key elements in implementing industrial projects aimed at improving new-product development (NPD) processes, especially when e-collaboration utilities ... -
Algorithmic Perception of Vertices in Sketched Drawings of Polyhedral Shapes
Company, Pedro; Plumed, Raquel; Varley, Peter; Dorribo Camba, Jorge Association for Computing Machinery (ACM) (2019-09)In this article, visual perception principles were used to build an artificial perception model aimed at developing an algorithm for detecting junctions in line drawings of polyhedral objects that are vectorized from ... -
An Algorithm for Grouping Lines Which Converge to Vanishing Points in Perspective Sketches of Polyhedra
Company, Pedro; Varley, Peter Ashley Clifford; Plumed, Raquel Bart Lamiroy & Jean-Marc Ogier (2014)We seek to detect the vanishing points implied by design sketches of engineering products. Adapting previous ap- proaches, developed in computer vision for analysis of vectorised photographic images, is unsatisfactory, as ... -
An optimisation-based reconstruction engine for 3D modelling by sketching
Company, Pedro; Contero, Manuel; Conesa, Julián; Piquer, Ana Elsevier (2004-12)An engine that automatically reconstructs a large variety of polyhedral, origami and wire-frame objects from single-view sketched drawings generated in a calligraphic interface is presented. The engine has two stages. An ... -

Approach for developing coordinated rubrics to convey quality criteria in MCAD training
Company, Pedro; Contero, Manuel; Otey, Jeffrey; Plumed, Raquel Elsevier (2015-06)This paper describes an approach to convey quality-oriented strategies to CAD trainees by embedding quality criteria into rubrics so as to force CAD trainees to understand them early in their instruction. To this end, the ... -
Assessment of Parametric Assembly Models Based on CAD Quality Dimensions
Otey, Jeffrey; Company, Pedro; Contero, Manuel; Dorribo Camba, Jorge Taylor & Francis (2018)An approach to convey CAD quality - oriented strategies to beginning users to create bottom - up assemblies is described . The work builds on previous efforts in the area of single part ... -
