Different CAD systems may be used by different companies which, when it comes to sharing data from one system to another, can cause incompatibility issues. It may require a company to buy a specific seat of a different CAD system, just so they can access the data being sent.
The alternative option is to translate your 3D CAD data. Data translators enable data exchange and data sharing of incompatible data formats. They are a high quality, cost-effective method of exchanging data between CAD system A and CAD system B for example. They remove the need to purchase additional CAD seats (that may require specialist knowledge) and can be used interactively from within your vendor specific application.
