In this demo paper, we present ""CAD-SE"" a search engine for CAD models in the domain of room planning. Many furniture manufacturers offer 3D CAD models for their products in various formats on their websites. Those models are used by architects and interior designers. Getting such models, however, is cumbersome as there is no common interface for the fast retrieval of CAD-files, e.g., using the product name, nor is there a central archive of such files. Project CAD-SE solves this problem by offering a search engine that is capable of understanding manufacturers pages, and linking product description sites with download sites for CAD files in various formats.
