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 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 ... -
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 ... -
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 ... -
CAD training for digital product quality: a formative approach with computer‑based adaptable resources for self‑assessment
Agost, Maria-Jesus; Company, Pedro; Contero, Manuel; Dorribo Camba, Jorge 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 ... -
Extended 3D annotations as a new mechanism to explicitly communicate geometric design intent and increase CAD model reusability
Dorribo Camba, Jorge; Contero, Manuel; Johnson, Michael; Company, Pedro Elsevier (2014-12)A successful implementation of the Model-Based Enterprise concept (MBE) requires maximizing the potential benefits of annotated 3D models. The foundations of the MBE model are established by digital product definition data ... -
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 López, David; Dorribo Camba, Jorge Springer-Verlag (2018-06)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 the ... -
On the Integration of Model-Based Feature Information in Product Lifecycle Management Systems
Dorribo Camba, Jorge; Contero, Manuel; Company, Pedro; Pérez, David Elsevier (2017-12)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, Ferrán; Contero, Manuel; Dorribo Camba, Jorge CAD Solutions (2020)The assurance of model quality in parametric CAD implies that designers must build models that facilitate reuse while retaining their design intent when modified. In this context, a suitable selection of geometric constraints ... -
Parametric CAD modeling: An analysis of strategies for design reusability
Dorribo Camba, Jorge; Contero, Manuel; Company, Pedro Elsevier (2016-05)CAD model quality in parametric design scenarios largely determines the level of flexibility and adaptability of a 3D model (how easy it is to alter the geometry) as well as its reusability (the ability to use existing ... -
Revisiting the Design Intent Concept in the Context of Mechanical CAD Education
Otey, Jeffrey; Company, Pedro; Contero, Manuel; Dorribo Camba, Jorge Taylor & Francis (2018-01)Design intent is generally understood simply as a CAD model’s anticipated behavior when altered. However, this representation provides a simplified view of the model’s construction and purpose, which may hinder its general ... -
Sketch-Based Modeling in Mechanical Engineering Design: Current Status and Opportunities
Dorribo Camba, Jorge; Company, Pedro; Naya, Ferran 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 ... -
Teachers as Designers of Formative e-Rubrics: A Case Study on the Introduction and Validation of Go/No Go Criteria
Company, Pedro; Otey, Jeffrey; Agost, Maria-Jesus; Contero, Manuel; Dorribo Camba, Jorge Springer Verlag (2019-07-18)Information and Communications Technologies (ICTs) offer new roles to teachers to improve learning processes. In this regard, learning rubrics are commonplace. However, the design of these rubrics has focused mainly ... -
The Cost of Change in Parametric Modeling: A Roadmap
Dorribo Camba, Jorge; Contero, Manuel; Company, Pedro; Hartman, Nathan CAD Solutions (2021)In this paper, we lay the foundation for estimating the cost associated to parametric modeling changes and discuss its implications on the broader context of engineering change management. We provide an analysis of the ... -
