Abstract: A market-based search system uses a digital geometric CAD model as a filter against other digital geometric CAD models that have been used or that may be used to produce actual products and that have real-world cost and other transactional data. Specifically, a digital CAD model is used as an index into market-based data. A geometry based search engine can perform a first pass of comparing indexed parameters derived from the CAD model provided in a search query against index data of an indexed CAD assets database. A transaction search engine can then be used to perform a second pass on the results from the geometric based search in order to match any transactional data, process data, or technical attribute data of the CAD model with real-world transactional data and/or process data associated with CAD models discovered by the indexed data search.
