Flattening without Torsion

To reduce layout manipulations, you can generate a torsion-free flattened harness. You can flatten the entire or partial harness without torsion.

Before you begin:
  • In Me > Preferences > App Preferences > 3D Modeling > Electrical and Electronic Systems > Electrical Manufacturing Preparation, select the Make support not constraining option.
  • In a first tab, open the product containing the 3D harness content.
  • In a second tab, create a product and activate it.

  1. From the Formboard section of the action bar, click Harness Flattening Parameters , and define the parameters as follows:
    1. In the General tab, choose an Active plane.
    2. In the Flattening Orientation tab, select the Torsion free harness parameter.

    For more information, see Defining Harness Flattening Parameters.

  2. From the Formboard section of the action bar, click Extract to duplicate the 3D harness content.
    The Extract Report panel appears and the harness is extracted.

  3. To flatten the extracted content, from the Formboard section of the action bar, click Generate Layout , and then select either of the following:
    • An electrical geometry or an electrical physical system
    • A branch or a device
    The whole network is highlighted and the Generate Layout dialog box appears.

  4. Under Angle Mode, select Standard and then click OK.

    Note: By default, this mode is selected.

    The layout is generated:
    • The main device of the harness is flattened according to the flattening parameters defined.
      Note: For more information about how the main device is identified and oriented when the Torsion free harness parameter is selected, see Device Orientation.
    • The branch connected to the main device is flattened straight.
    • The rest of the geometry is positioned so as to nullify torsion.


  5. Optional: Click Analyze Torsion , and then select the flattened geometry.
    The content is torsion-free.
