Abstract

Methods and systems for automatically translating geometric data, such as a CAD model, from a primary file format to a secondary file format. In one embodiment, the method is carried out on a server computer that receives CAD model information and translation requirements via the Internet or an intranet computer system. For example, the server can receive a CAD model name, a secondary file format, a translation protocol, a neutral file format, a translation accuracy, and a destination for the translated model. The geometric data translation system then automatically translates the selected model in accordance with the translation requirements received. When the translation is complete, the system can automatically transmit an electronic notification to the user indicating whether or not the translation was successful. In one embodiment, this notification can include the resulting accuracy of the translation.
