Drawing freehand sketches of mechanical components on multimedia devices for AI-based
engineering modeling has become a new trend. However, its development is being …

As the production orders are becoming multi-category and small-batch in the era of product
personalization, these require frequent reconfiguration of reconfigurable flexible assembly …

Sketch-based modeling has attracted considerable attention in recent years. In this paper,
we propose a semantic feature modeling system for sketch-based jewelry design, called …

The aim of this paper is to provide a review of the characteristics of 3D solid modeling
software libraries–otherwise known as' geometric modeling kernels' in non-manifold …

There is an increasing need for building models that permit interior navigation, eg, for
escape route analysis. This paper presents a non-manifold Computer-Aided Design (CAD) …

Parts accuracy evaluation is essential to ensure conformance with expected tolerances. On-
machine inspection or coordinate measuring machines are commonly employed to measure …

Assembly tooling design is implemented according to the constraints of geometric
information and technical requirements of aircraft. Changes in aircraft parts will cause …

Simplicial complexes are extensively used for discretizing digital shapes in two, three, and
higher dimensions within a variety of application domains. There have been many proposals …

Topology authentication for computer-aided plant design (CAPD) models features
intrinsically complex topological relations. This study investigates a semi-fragile …

为了提高基于网格模型的算法与应用的效率和稳定性, 提出一种将任意多边形网格模型转化为
正则三角网格模型的算法. 首先对输入多边形网格模型中非三角形的面片进行三角剖分 …
