Tool attachment is an assembly of a tool and an attachment. The tool and the attachment can be part models or subassemblies.

When a tool attachment is used in an NC sequence, you can use the TOOL_ATTCHMENT parameter for Creo NC to identify the attachment from the tool attachment assembly. You can specify the TOOL_ATTCHMENT parameter while defining or modifying a part or subassembly. The possible values for the TOOL_ATTCHMENT parameter are YES and NO. For the attachment part or assembly the value must be set to YES.

While defining an NC sequence, Creo NC identifies the attachment part or assembly by the value of the TOOL_ATTCHMENT parameter. This part or assembly is then automatically used as the attachment for the NC sequence.
