Currently, the content-based retrieval is a problem of major interest in several different fields
and, focusing on mechanical engineering, many approaches exist to compare and retrieve …

The work here presented is part of a wider research project aimed at extracting and using in
industrial applications high level semantic information from 3D product models that are …

Many types of heterogeneous CAD models created by previous product development
activities are stored in enterprise databases. Searching reusable CAD models for engineer …

Content-based shape retrieval techniques can facilitate 3D model resource reuse, 3D model
modeling, object recognition, and 3D content classification. Recently more and more …

Being able to reuse existing design knowledge is of major interest to help designers during
the creation of new products. This is true at the level of the parts and even more at the level …

Content-based CAD assembly model retrieval focusing on similarity measure of bottom-level
geometry and topology information can hardly meet design demand of engineering …

Abstract 3D CAD models have great significances for product lifecycle reuse as each model
aggregates abundant knowledge in a vivid 3D CAD model and enables engineers to reuse …

An assembly provides significant knowledge in design reuse, since it can represent parts
information and their relationships comprehensively. The retrieval of assembly has the …

In this paper, we report on a data analysis process for the automated classification of
mechanical components. In particular, here, we describe, how to implement a machine …

Abstract The use of Digital Mock-Up (DMU) has become mainstream to support the
engineering activities all along the Product Development Process. Over the years …
