Assigning Requirements to Instructions from Assignment Manager

You can publish all Functional Tolerancing and Annotation (FTA) as individual requirements. Each requirement contains the geometry (CGR) of the FTA. Selecting the FTA Requirement in the 3D or the FTA Requirements panel, then the associated feature/surface cross-highlights.

Assign a Requirement to Textual Instructions without prerequisite action to assign a requirement to the parent Operation.

Before you begin:

Open your data, which must contain system and manufacturing assembly structures and have completed these steps from this scenario. Set data using CATIA 3D Tolerancing & Annotation, and Manufactured Item Definition app.

In Work Instructions app, through the ‘Assignment manager’ command launched on a selected Textual Instructions (in the Instructions panel) you are able to assign/Unassign requirements.

The Assignment of the Requirement to Textual Instructions is possible without prerequisite action to assign the requirement to the parent Operation. If the requirement is not already linked to the parent Operation, the link automatically creates during the application of the command.

  1. Select an Operation, Op30.
  2. Select Create Text Instruction.
  3. Click Assignment Manager.
    The Assignment Manager opens for Textual Instructions, Instruction for OP30.

  4. Select the requirements for this operation, and Assign Selected Requirements .


    To change the rank value among requirements, when selecting the requirement in the assigned list, then the commands in the side panel enable. You can now move requirements up, down and to move the selected requirement after a particular requirement.

    • Move Requirement Up
    • Move After Requirement
    • Move Requirement Down
    Rank Column:
    • For assigned requirements and Rank Value - Assigning a requirement to the operation, the rank column populates for the assigned requirement. No inputs required from you for the rank calculation. The rank calculation is automatic. For example, a first assigned requirement has a rank 1 and the next assigned requirement has a rank 2.
    • Changing the Rank of assigned requirement - Change the rank by moving the requirement up or down using the arrow provided below the filter in the assigned requirement list.
    • Sorting requirements on Rank column - Similar to regular sorting on various columns in the Assignment Manager, sort assigned requirements based on the rank column.
    • Persistence of assigned Rank - The rank of the assigned requirement needs persistence irrespective of the current session. Closing and reopening the assignment manager, or a new session, the previous ranks must restore.

  5. Assign Requirements to OP 40 using Assign Selected Requirements .
