General Definitions

###

Open CASCADE general definitions for Data Exchange include several enumerations and classes. These are used by both the IGES and STEP data exchange processors.

To define translation parameters and file headers, you can use:

- Interface_InterfaceModel

- Interface_Static

To manage Message display, you use Interface_TraceFile.

To define the type of analysis of the source file, and to ensure the success of the loading operation, you use the following enumerations from the IFSelect package:

- PrintCount

- ReturnStatus

To read and write attributes such as names, colors, layers for IGES and STEP and validation properties and structure of assemblies for STEP, you can use an XDE document.
