Auto-numbering of Part Numbers and File Names
Automatic numbering is supported in Windchill Workgroup Manager for CATIA 3DEXPERIENCE and is enabled by default. Whenever a new CAD document is created from CATIA 3DEXPERIENCE (directly or by using a Save As action), a number generated from Windchill is automatically assigned to the title of the document. This title is unique in Windchill and by default, is also used as the number of the corresponding EPM document in Windchill once the CAD document is checked in.
With auto-numbering enabled, you can accept the auto-generated number, or enter a custom value for the title. If a CAD document was previously created in CATIA 3DEXPERIENCE using auto-numbering, you can change the part number in the native Properties window.
The following conditions are required for proper operation of auto-numbering.
• The CAD tool is connected to Windchill Workgroup Manager for CATIA 3DEXPERIENCE.
• Windchill Workgroup Manager for CATIA 3DEXPERIENCE has an active Windchill server registered.
* 
• If you want to disable auto-numbering, set the Windchill preference Sychronize Number and File Name to No for CATIA 3DEXPERIENCE. For more information, see Preferences Managed in the Windchill Preference Management Utility.
• When automatic numbering is disabled, the title of a new CAD document is based on the native CATIA 3DEXPERIENCE configuration setting.
Other Preference Settings
Consider how the following preferences in the Windchill Preference Management utility affect auto-numbering.
• CAD Document Number System Attribute—Set this to identify the system property in CATIA 3DEXPERIENCE that shows the CAD document number.
• Synchronize Number and File Name—Set this to No for CATIA 3DEXPERIENCE if you want to disable automatic numbering.
• Drop File Extension From Name—Set this to Yes for CATIA 3DEXPERIENCE if you want an auto-generated Windchill part name that does not include the file extension.
• Drop File Extension From Number—Set this to Yes for CATIA 3DEXPERIENCE if you want an auto-generated Windchill part number that does not include the file extension.
• Naming Parameter—Set this to specify the CATIA 3DEXPERIENCE designated parameter from which the CAD document name is copied.
• Numbering Parameter—Set this to specify the CATIA 3DEXPERIENCE designated parameter from which the CAD document number is copied.
