G.1 Introduction

This appendix lists the attribute callback functions that can be implemented to replace or extend the normal attribute handling process in Parasolid.

Further information on the use and effects of attribute callback functions can be found in the following chapters of the Parasolid Functional Description:

• Chapter 93, “Attribute Definitions”
• Chapter 94, “Attributes”

G.2 Registering the attribute callback functions

The attribute callback functions must be registered with Parasolid by calling the PK function PK_ATTDEF_register_cb, at any time during a Parasolid session.

The functions can then be enabled and disabled during a modelling session by the PK function PK_ATTDEF_set_callback_flags.

G.3 Attribute callback functions that can be registered

This section lists the attribute callback functions that you can register during a Parasolid session. You do not need to register all of these callback functions; if there are any you do not wish to use, then set the relevant field in the callbacks structure passed to PK_ATTDEF_register_cb to null .
