Moving Elements by Symmetry

The Symmetry command moves existing sketcher elements according to a line, construction line, or an axis but do not duplicate elements, contrary to Mirror.

This task shows you how to:

Before you begin:

Create the elements to be moved and an axis.

Moving One Element

To move an element symmetric about an axis, you can use the Symmetry command.

  1. From the Sketch section of the action bar, click Symmetry .
  2. Select the element you have created and click on the axis.



    The element is moved by symmetry according to the axis.



Moving Several Elements on Each Side of the Axis

You can move several elements on each side of the axis at a time. To be able to multi-select elements, the axis must be quite long.

Before you begin:

Create an axis, then create different elements on the either side of an axis.

  1. Click Symmetry .
  2. Select the elements. To be able to multi-select elements, the axis must be quite long.
  3. Click on the axis.


    The symmetry is created and the two elements are taken into account.



Apply Constraints to Symmetrical Elements

The constraints applied on an axis are kept after the symmetry operation.

Before you begin:

Create an element to be moved and an axis.

  1. From the Sketch section of the action bar,, click Constraint .
  2. Select the element and the axis.
  3. Click to create the constraint. The constraint and its value are displayed in the work area.


  4. Click Symmetry .
  5. Select the element and then click on the axis. The element is moved by symmetry according to the axis. Note that as the constraint is applied on an axis, the constraint is kept after the symmetry.


    Notes:
    • Only internal constraints are kept after a symmetry operation.
    • The constraint is also kept when it is applied to a fixed element.
    • In the case of Use Edges, the element becomes isolated.
