3D Model / CAD / Assembly / Retrieval

3D CAD systems are widely used in designing products. We develop efficient systems for retrieving 3D CAD assembly models with high precision. A 3D CAD assembly model consists of multiple components which have various shapes and are made by various materials. The existing CAD models can be used to construct new models without the same defects as them efficiently. Our systems can distinguish not only shapes of assembly models but also layouts of their components which have the same shapes and are made of different materials.
