The Export tab allows you to export a model to CAD line and surface data or finite element models.
The Custom option allows you to export models using your own custom-built export translator. The Custom option can also be used to export models using a translator provided with the installation but which is not directly accessible via the default menu. To access the Custom option, set the File type field in the Export tab to Custom.
The Export tab allows you to write information from a database to many finite element formats. However, geometry data can only be written in IGES format.
