[EN] 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

González-Lluch, C.; Company, P.; Contero, Manuel; Camba, J.D.; Plumed, R. (Elsevier, 2017-02)

[EN] 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. ...
Aplicación de las tecnologias C.A.D al diseño optimo interactivo de estructuras mediante programación matemática no lineal

Company Calleja, Pedro-Pablo (Universitat Politècnica de València, 1989-02-08)
Assessment of parametric assembly models based on CAD quality dimensions

Otey, Jeffrey; Company, Pedro; Contero, Manuel; Camba, Jorge D. (CAD Solutions, 2019)

[EN] 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 history-based, feature-based parametric ...
CAD training for digital product quality: a formative approach with computer-based adaptable resources for self-assessment

Agost, Maria-Jesus; Company, Pedro; Contero, Manuel; Camba, Jorge D. (Springer-Verlag, 2022-04)

[EN] 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 ...
Implementation of Adaptable Rubrics for CAD Model Quality Formative Assessment

Company, P.; Otey, Jeffrey; Contero, Manuel; Agost, M.J.; Almiñana, A. (TEMPUS PUBLICATIONS, DUBLIN INST TECHNOLOGY, BOLTON ST, DUBLIN, IRELAND, 2016)

[EN] Evaluation rubrics are helpful as formative tools to convey quality criteria from the beginning of the training period of future mechanical CAD users. But rubrics should provide feedback and evolve dynamically to adapt ...
On the effects of the fix geometric constraint in 2D profiles on the reusability of parametric 3D CAD models

González-Lluch, Carmen; Company, Pedro; Contero, Manuel; Pérez Lopez, David Clemente; Camba, Jorge D. (Springer-Verlag, 2019-09)

[EN] In order to be reusable, history-based feature-based parametric CAD models must reliably allow for modifications while maintaining their original design intent. In this paper, we demonstrate that relations that fix ...
On the integration of model-based feature information in Product Lifecycle Management systems

Camba, J.D.; Contero, Manuel; Company, P.; Pérez Lopez, David Clemente (Elsevier, 2017)

[EN] As CAD models continue to become more critical information sources in the product's lifecycle, it is necessary to develop efficient mechanisms to store, retrieve, and manage larger volumes of increasingly complex data. ...
On the role of geometric constraints to support design intent communication and model reusability

Company, Pedro; Naya Sanchis, Ferran; Contero, Manuel; Camba, Jorge D. (CAD Solutions, 2020)
