Defining Template Structure—Extended Exercises

Purpose: The purpose of this exercise is to define alternate parts and dependencies, and to familiarize yourself with the access control functionality for alternates. The exercise also takes you through on how to change the prime part and on adding a structure position in your own serial structure template for the simplified landing gear. You will also learn to create a new template by importing a product structure, create a template from a branch of an existing template and in the end, and phase out a configuration.

Define Template Alternate

Purpose: The purpose of this exercise is to define alternate parts that can be used in a structure. You are going to define:

  1. Revision * and revision 1 as mutually interchangeable revisions of the nX72ENG7010 - Engine 

  2. Part nX72ENG7010 rev * as one way interchangeable with part X72ENG7010  rev *

  4. Repeat the same for the template alternates you have created in the Define Template Alternate exercise. 

Define Dependencies

Purpose: The purpose of this exercise is to define dependencies in a structure. In the previous exercises you have defined different alternates for the engine. You are now going to define dependencies between the two engines. If engine alternate X32ENG7010 rev * is used in one position, the other engine position requires the same engine installed.

Prerequisite: The previous exercise must have been completed.

  7. Click OK.
  8. Click the Consist Of tab to make sure that the product structure has been imported.

Create Template from Sub Structure

Purpose: The purpose of this exercise is to create a template structure from a branch of an existing template structure. You are going to create a template structure for the Leg Assembly X32LEG7004, rev 0n that you just imported in the previous exercise.

Prerequisite: The previous exercise must have been  completed.

Windows:
Serial Structure Template

  1. Open the Serial Structure Template window. 
  2. Query (F3) for Part Number and Template Part Number X32NLG7001, revision 0n.
  3. Click the Consist Of tab and observe the structure. Make sure that the check box Configured in Separate Template is not selected.
  4. Select the row containing the part number X32LEG7004, right-click, and then click Create Template from Sub Structure.
  5. Verify that the information is correct and all the check boxes you want to use are selected.
  6. Click Finish to create the template.
  7. Verify that the check box Configured in Separate Template is selected. A template is created which can be used in other template structures.
  8. Right-click on window header, point to Status, and then click Set Active.  Note: This operation is irreversible.
  9. Click the General tab and verify that the Structure Status field displays Active.
  10. Your template structure is now ready to build serial structure upon.

Phase Out a Configuration
