Modifying the Axis System

Axis systems are used in the definition of preprocessing specifications such as loads, restraints, 3D properties, connection properties (for example: force, advanced restraint, stiffness), and also in the image definition. The components of this force, advanced restraint, or stiffness are defined relative to the specified coordinate system.

Important: Left-handed axis systems are not supported.

Modify the Axis System in a Preprocessing Specification Context

You can modify the axis system of preprocessing specifications (loads, restraints, 3D properties, connection properties). When you create a preprocessing specification in a simulation, you can choose the axis system and the coordinate system you want to use to define the components of the preprocessing specification. The type of axis system you can choose depends on the preprocessing specification you create.

To modify the axis system of a preprocessing specification:

  1. In the Type list, select one of the following:

    • Global to use the default main axis system.
    • Implicit to use a local coordinate axis system computed on the selected support.
    • User to use an axis system you created (for example in the Part Design workbench or the Generative Shape Design workbench).
    • Local to use a axis system that is locally defined relative to a finite element.



  2. If you selected User:

    1. Select the axis system in the specification tree.

      The name of the selected axis is displayed in the Current axis box.

    2. Select the type of coordinate system you want to use: Cartesian, Cylindrical or Spherical.

      See Coordinate System.

  3. To display the selected axis system locally on the geometry, select the Display locally check box.

    Important: This option is available only in the context of the command.


    • Display locally option deactivated with a Global axis system:

    • Display locally option activated with a Global axis system :

Modify the Axis System in an Image Context

You can modify the axis system used in the image edition and when you export data to a file.

To modify the axis system in the context of the image edition and the export data to file capabilities:

  1. Click .

    The Axis System dialog box appears.

  2. In the Type list, select one of the following:

    • Global to use the default main axis system.
    • User to use an axis system you created (for example in the Part Design workbench or the Generative Shape Design workbench).
    • Manual to use an axis that you define by specifying the origin and the X, Y and Z axes.
    • Local to use a axis system that is locally defined relative to a finite element.

  3. If you selected User, select the axis system in the specification tree.

  4. If you selected Manual, enter the coordinates of the origin and the coordinates of two axes.



  5. In the Coordinate system list, select the type of coordinate system you want to use: Cartesian, Cylindrical or Spherical. See Coordinate System.

  6. Click OK.
