The goal of this SGER is to explore the feasibility of a web-based CAD search engine to allow the designer to efficiently find qualified prospects for contract manufacturing in real time from a pool of globally distributed contract manufacturers. This would require a search system that will allow OEM companies to search for and qualify potential contractors through coded CAD data in addition to current text searches, allowing product shape to be mathematically converted into searchable code. The exploratory research will determine the feasibility of converting the description of a product's shape from its Boundary Model Representation (B-Rep) as represented by the theory of solid modeling into a boundary value problem as governed by field theory. The tasks include determining if a code or "fingerprint" of a mechanical product shape can be mapped through electrostatic field analysis. In order to have significant broader impact on the potential industrial applications in purchasing and production planning, this mapping must be an efficient and secure method for CAD data coding and classification

该SGER的目的是探索基于Web的CAD搜索引擎的可行性，以使设计人员可以从全球分布式合同制造商池中有效地实时找到合同制造的合格前景。这将需要一个搜索系统，该系统将使OEM公司除了当前的文本搜索之外，还可以通过编码的CAD数据搜索并验证潜在的承包商，从而可以将产品形状数学地转换为可搜索的代码。探索性研究将确定从其边界模型表示形式（B-REP）转换产品形状的描述的可行性，该理论由实地理论所控制的固体建模理论为边界价值问题。任务包括确定机械产品形状的代码或“指纹”是否可以通过静电场分析映射。为了对购买和生产计划的潜在工业应用产生更广泛的影响，该映射必须是CAD数据编码和分类的有效且安全的方法
