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 …

Machining is the main method of forming parts/products. The traditional 2D machining
technology can no longer meet the requirements of modern manufacturing. Machining …

Parametric computer-aided design (CAD) is the dominant paradigm in mechanical
engineering for physical design. Distinguished by relational geometry, parametric CAD …

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 …

Abstract 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 …

With the increasing popularity of consumer-grade 3D printing, many people are creating,
and even more using, objects shared on sites such as Thingiverse. However, our formative …

ABSTRACT The Computer Aided Design has constantly evolved since its appearance at the
beginning of 1960s. This work summarize the history of CAD and analyze the development …

An important area of reverse engineering is to produce digital models of mechanical parts
from measured data points. In this process inaccuracies may occur due to noise and the …

Abstract Design pattern is widely used in the software engineering field, which enables
designers to reuse existing mature designs from a high level perspective. Inspired by this …

Detecting global exact symmetries in CAD models is of great importance in the research of
CAD/CAE integration. Therefore, a method is proposed in this paper to rapidly detect the …
