[EN] 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, ...
[EN] 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 ...
[EN] We present a database architecture for exploring, classifying, and visualizing feature-based parametric CAD models based on quantitative complexity metrics. The system consists of (1) an external relational database ...
[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. ...

[EN] In this paper, we describe a voice-based interaction mechanism to annotate 3D models directly from a computer-aided design (CAD) modeling environment. The audio signal is captured and automatically transcribed to a ...
[EN] Traditional interaction mechanisms in distributed digital spaces often fail to consider the intrinsic properties of action, perception, and communication among workgroups, which may affect access to the common resources ...
[EN] Recent advances in graphics hardware technology are enabling the development of increasingly more sophisticated virtual reality (VR) applications. However, the representation of 3D virtual models in this medium requires ...

El proyecto de investigación propuesto se enmarca dentro del área de diseño de producto con aplicaciones de modelado sólido CAD/CAM (Computer Aided Design/Computer Aided Manufacturing). Concretamente, se pretende hacer ...
[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 ...
[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 ...
[EN] Modern manufacturing companies operate in environments characterized by increasingly shorter development cycles and the need to develop highly customizable products at competitive prices. In this paper, we examine the ...
[EN] The robustness and flexibility of a feature-based parametric CAD model determines the extent to which the geometry can be modified and reused in other design scenarios. The ability of a model to successfully adapt to ...

[ES] Las técnicas de visualización innovadoras están transformando la presentación de productos y desempeñando un papel crucial en un mercado altamente competitivo. Las tecnologías de Realidad Virtual (RV) y Mixta (RM) ...
[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 ...
[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. ...
[EN] 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 ...
[EN] 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 ...
[EN] 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 ...
[EN] 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 ...
