The integration of Artificial Intelligence and Machine Learning technologies into Computer-Aided Design systems represents a transformative approach to addressing longstanding challenges in engineering design processes. Traditional metadata-based search methods have proven inadequate for efficiently locating existing components, resulting in significant economic losses across manufacturing sectors. Shape-based search emerges as a compelling alternative, leveraging advanced deep learning architectures to enable intuitive geometric similarity matching. This capability fundamentally alters how engineers interact with design repositories, allowing for component retrieval based on visual similarity rather than textual descriptions. The implementation of shape-based search yields substantial benefits, including dramatic reductions in search time, increased component reuse rates, and enhanced design standardization. While integration challenges exist, organizations successfully deploying these technologies report compelling return on investment through reduced development cycles and lower certification costs. As computational technologies continue to advance, the application of geometric deep learning to CAD search promises to further revolutionize engineering knowledge management by enabling cross-domain component discovery and function-based retrieval capabilities.
