Rolling Branches

You can roll the required portions of a branch.

Important:
  • The creation and the edition of a roll are always performed on the same local plane.
  • On the context toolbar, click Local mode to roll the branches. You can click Punctual mode to roll only the segment of the branch or the protections.
  • During manipulations, if the roll is not compatible with the properties of the segments within the branch, the manipulator becomes orange and a warning icon appears.

This task shows you how to:

Before you begin:
  • Flatten the harness geometry.
  • From the Formboard section of the action bar, click Prepare Layout .
  • On the context toolbar, click Roll .

Roll a Branch Portion

You can roll a branch portion by defining a bend angle, and then manipulating the roll radius and the roll center.

  1. To roll the portion of a branch:
    1. Hover over the branch to define the position of the roll center.
      A yellow sphere is displayed, following the position of the pointer.
    2. Click the branch to validate the position.
      In the 3D area:
      • The yellow sphere turns green and indicates the position of the roll center.
      • An angle editor is displayed.
    3. Select the portion of the branch to be rolled.
      The angle editor position is updated according to the position of the pointer.

    4. Click the branch to select the portion.
      In the 3D area:
      • The branch is highlighted.
      • The Robot is snapped to the sphere.
    5. Drag the branch to roll the selected portion.
      Tip: To roll the portion, you can do either of the following:
      • Rotate the arc of the Robot.
      • Drag the triangular manipulator from the angle editor.
      • Click the angle value to enter a precise angle, and then press Enter to apply the value.
  2. To edit the radius of the roll:
    1. Hover the pointer over the roll position.
      A radius manipulator is displayed.

    2. Drag the triangular manipulator to edit the radius.



      Tip: You can also click the radius value to enter a precise radius, and then press Enter to apply the value.

      In the 3D area, the roll center is moved and the roll radius is updated.
  3. To edit the position of the roll center:
    1. Hover the pointer over the portion of the branch which is not rolled.
      A ruler manipulator appears with a yellow anchor , displaying 0 at the branch end.

      To change the reference point (start point) of the ruler, you can click any of the green anchors that appear at a branch point, a support point, and a protection point on the rolled branch. You can extend the rolled portion up to the new reference point.


      Note: If the support or the protection is moved, the roll start point remains unchanged.
    2. Drag the triangular manipulator to edit the position of the roll center on the branch.


      In the 3D area, the position of the roll center is updated. The roll angle and roll radius are not modified.

  4. To cancel the manipulations, press Escape.
  5. To validate the manipulations, click in the 3D area.
    You can now roll other branch portions or click Prepare Layout to exit the command.

Edit a Rolled Portion

You can modify the roll applied to a branch.

Note: If you edit a branch rolled in a local plane you manually selected, the edition is performed in the same local plane.

  1. Select a rolled portion:
    1. Hover over the branch to display the yellow sphere that symbolizes the roll center.


    2. Click the bend position.
      The yellow sphere turns green and the angle editor is displayed.

  2. Select the rolled portion to be edited:
    1. Hover over the branch.
      The angle editor position is updated according to the position of the pointer.
    2. Click the branch to select a portion.
      In the 3D area:
      • The branch is highlighted.
      • The Robot is snapped to the roll position.

      Now you can:

      • Drag the branch to edit the roll angle.
      • Hover over the roll position and drag the manipulator to edit the roll radius.
      • Hover over the branch section which is not rolled and drag the manipulator to edit the position of the roll center.

      For more information, see Roll a Branch Portion.

  3. Optional: To change this start point of the ruler, click any of the anchors that appear at a branch point, support point, and protection point on the rolled branch. You can extend the rolled portion up to the new reference point.

    Scale Adjusted Based on New Start Point

    Note: If the support or the protection is moved, the roll start point remains unchanged.
