Generating Manufacturing Information Using NC-XML Files
Use the 
Generate Information Using the NC-XML File action present in the Process Plan Browser to generate manufacturing information from the NC-XML file. You can select one or more operations present in the Structure tab of the Process Plan Browser and launch this action. You can also select sub-operations. You can generate manufacturing information from a CAD document that has a valid NC-XML file attached as a secondary content file, or from a Windchill document that has a valid NC-XML file attached as a primary content file. So, as a prerequisite, you must attach an existing CAD document as a secondary content file or an existing Windchill described by document as a primary content file. For more information, see Associating a Document with an Object. Also, the entities mentioned in the NC-XML files must be present in the Windchill database. For example, a tool mentioned in the NC-XML file must be present in the Windchill database.

Key Points
• Consider that you launch the Generate Information Using the NC-XML File action. After its implementation, you made changes to the same secondary content file or primary content file. In such a case, when there is a change in the information in the attached NC-XML file, you can use the Generate Information Using the NC-XML File action again to update the manufacturing information in Windchill. The process described above remains the same. The system makes the changes accordingly, as specified in the NC-XML file.

The following preferences are related to the Generate Information Using the NC-XML File action:
Generate Information Using the NC-XML File action:• Use the Search Criteria to Allocate Tooling to NC Generated Operations preference to specify the search criteria to be used for searching the existing tooling and work center information in the Windchill database and allocate to NC generated operation. OOTB search is based on the Number attribute.
• When you launch the Generate Information Using the NC-XML File action, the system searches for the tooling and work center information inside the Windchill database. It then allocates the Tool or work center to the operation as per the option selected in the Applicable Object Mapping preference. Use the Applicable Object Mapping preference to define the type of criteria used during the Generate Information Using the NC-XML File action. The working of this preference depends on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. The system searches for the entity based on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. The possible values for the Search Criteria to Allocate Tooling to NC Generated Operations preference are Name and Number. The possible values for the Applicable Object Mapping preference are as follows:
Generate Information Using the NC-XML File action. The working of this preference depends on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. The system searches for the entity based on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. The possible values for the Search Criteria to Allocate Tooling to NC Generated Operations preference are Name and Number. The possible values for the Applicable Object Mapping preference are as follows:◦ Tooling —The system searches for the Tooling or Part object depending on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. If it finds the Tooling or Part object, it allocates the same to the operation.
◦ CAD Document — The system first searches for the CAD Document depending on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference.. If it finds the CAD document, it allocates the associated resource to the operation.
◦ CAD Document/Tooling — The system first searches for the CAD Document depending on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference.. If it finds the CAD document, it allocates the associated resource to the operation. If the CAD document is not found, the system searches for the Tooling or Part object in the Windchill database and allocate the same to the operation.
• Use the Search Criteria to Allocate Tooling to NC Generated Operations preference to specify the search criteria to be used for searching the existing tooling and work center information in the Windchill database and allocate to NC generated operation. OOTB search is based on the Number attribute.
• Use the Mapping Attribute from NC-XML File for Resources Allocation preference to define the criteria to map the search attribute from the NC-XML file for resource allocation to operations. The possible values are Id (default) and InstanceName. The system uses these values to identify the tooling information in the NC-XML file. The working of this preference depends on the value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. When set to Id, the system searches for the Id value in the NC-XML file. Once it finds the Id value, it allocates the tooling information to the operation based on the attribute set in the Search Criteria to Allocate Tooling to NC Generated Operations preference. When set to InstanceName, the system searches for the InstanceName value in the NC-XML file. Once it finds the InstanceName value, it allocates the tooling information to the operation based on the attribute set in the Search Criteria to Allocate Tooling to NC Generated Operations preference.
Use Case
The possible values for the Search Criteria to Allocate Tooling to NC Generated Operations preference are Number and Name. The possible values for the Mapping Attribute from NC-XML File for Resources Allocation preference are Id and InstanceName. Consider the following scenarios:
Value set in the Search Criteria to Allocate Tooling to NC Generated Operations preference | Value set in the Mapping Attribute from NC-XML File for Resources Allocation preference | Description |
|---|---|---|
Number | Id | The system searches Id value in the NC-XML file. It also searches for the number. Based on the findings, the system allocates the tool to the operation. |
Number | InstanceName | The system searches for InstanceName of the tool in the NC-XML file. It also searches for the number. Based on the findings, the system allocates the tool to the operation. |
