|Abstract:||3D design retrieval works, which focus on geometric representations, can hardly obtain reusable CAD models. We propose a novel method to retrieve reusable CAD models using knowledge-driven partitioning based on modeling dependency graphs. In order to retrieve reusable results, two dependency-graph partitionings are given based on design knowledge. The first is a horizontal partitioning scheme to simplify CAD models and preserve their essential shapes. In order to support partial shape retrieval and reuse, another vertical partitioning segments sub-parts in a meaningful way. The main contributions include (1) a graph-based modeling knowledge representation; (2) knowledge-driven graph partitioning strategies for improving reusability of retrieved results; and (3) redesign supports by utilizing modeling expertise. The validity of the method is demonstrated with several retrieval cases of realistic CAD models.© 2010 CAD Solutions, LLC.|
