Focusing on 3D assembly models, this book provides a detailed exposition of the principles and methods for information mining and reusing for CAD models. The book is divided into four parts: Part 1 discusses the connotation of model information reusing and the current development state of related methods, analyzing the main components of reusable model information in the digital environment. Part 2 explores assembly model retrieval methods, explaining the principles and specific algorithms for assembly retrieval based on three ways of discrete component information, consideration of part connectivity, and construction of spatial connectivity skeletons. Part 3 delves into methods for mining common assembly structures, describing principles and algorithms for general structure mining based on attribute adjacency graphs and generalized adjacency graphs. Part 4 investigates assembly functional structure analysis and information reusing methods, presenting methods for mining the functional relationships of assembly structures based on functional information annotation and functional probability. Furthermore, the book introduces numerous 3D model examples to validate the proposed methods and help readers gain a deeper understanding of the application scenarios and effects of various methods.

This book is suitable as a reference for researchers and engineering technicians in the fields of computer-aided design, mechanical product development, and knowledge engineering platform construction. It can also be a reference book for teachers, graduate students, and senior undergraduate students of relevant majors in colleges and universities.
