Intelligent Part Comparison in Computer Aided Design

Increasing product complexity and customisation lead to a growing number of parts in computer-aided design, which poses a challenge for part management. This paper presents an approach for automated part comparison using part geometry representation. The solution involves converting CAD models, generating shape distribution histograms and using bounding box dimensions for part comparisons. The method, tested on an open source dataset and a large industrial dataset, shows significant improvements in the efficiency of identifying similar parts, making it highly applicable for industrial use.
