We introduce a computational framework for discovering regular or repeated geometric
structures in 3D shapes. We describe and classify possible regular structures and present …

Data-driven methods serve an increasingly important role in discovering geometric,
structural, and semantic relationships between shapes. In contrast to traditional approaches …

We introduce symmetry hierarchy of man‐made objects, a high‐level structural
representation of a 3D model providing a symmetry‐induced, hierarchical organization of …

We introduce the Symmetry Factored Embedding (SFE) and the Symmetry Factored
Distance (SFD) as new tools to analyze and represent symmetries in a point set. The SFE …

Finding design intent embodied as high-level geometric relations between a CAD model's
sub-parts facilitates various tasks such as model editing and analysis. This is especially …

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 …

This paper presents a simplification method for boundary representation (B-rep) models
using region suppression. This method suppresses every complex unwanted region of a B …

Shape idealization transformations are very common operations when adapting a CAD
component to FEA requirements. Here, an idealization approach is proposed that is based …

A construction tree is a set of shape generation processes commonly produced with CAD
modelers during a design process of B-Rep objects. However, a construction tree does not …
