CAD data exchange information

CAD data exchange is a method of drawing data exchange used to translate between different computer-aided design (CAD) authoring systems or between CAD and other downstream CAx systems.^[1]^: 157

Many companies use different CAD systems and exchange CAD data file format with suppliers, customers, and subcontractors.^[2] Such formats are often proprietary.^[1]^: 157 Transfer of data is necessary so that, for example, one organization can be developing a CAD model, while another performs analysis work on the same model; at the same time a third organization is responsible for manufacturing the product.^[3]

Since the 1980s, a range of different CAD technologies have emerged. They differ in their application aims, user interfaces, performance levels, and in data structures and data file formats.^[4] For interoperability purposes a requirement of accuracy in the data exchange process is of paramount importance and robust exchange mechanisms are needed.^[3]

The exchange process targets primarily the geometric information of the CAD data but it can also target other aspects such as metadata,^[1]^: 153 knowledge, manufacturing information, tolerances and assembly structure.

There are three options available for CAD data exchange: direct model translation, neutral file exchange and third-party translators.^[5]
