Significant progress has been accomplished during the past decades about geometric
constraint solving, in particular thanks to its applications in industrial fields like CAD and …

This paper presents a comprehensive review of geometric constraint solving in parametric
computer-aided design (CAD), with the major focus on its advances in the last 15 years …

摘要综述了几何约束求解的历史发展, 研究现状和应用= 对常见的# 类求解方法:
数值计算的方法, 符号计算的方法, 基于规则的方法, 基于图论的方法做了详细的介绍 …

In this paper, we propose a method which can be used to decompose a 2D or 3D constraint
problem into a C-tree. With this decomposition, a geometric constraint problem can be …

The very recent CAD paradigm of direct modeling gives rise to the need of processing 3D
geometric constraint systems defined on boundary representation (B-rep) models. The major …

3D models reconstructed from 2D sketches are inaccurate because of the inherent
inaccuracies in the input and the reconstruction method. It is therefore necessary to …

This thesis presents a new computer-aided design (CAD) modeling approach for three-
dimensional objects. Improving CAD modeling efficiency has always been a central topic in …

We propose a geometric constraint solving method based on connectivity analysis in graph
theory, which can be used to decompose a structurally well-constrained problem in 2D into …

Системы автоматизированного проектирования (далее–САПР) по праву считаются
одной из наиболее значимых для промышленности областей информатики. На …

In geometric constraints solving, the detection of dependences and the decomposition of the
system into smaller subsystems are two important steps that characterize any solving …
