Adding a Symmetric Constraint

  1. Activate the Symmetric constraint.
  2. Select the Make ends symmetric option (enabled by default) to make the curve end points symmetric.
  3. With the Select Axis of Symmetry tool guide active, select the axis about which the sketch objects are to be symmetric.
  4. With the Select Curves tool guide active, select the pair of curves to be made symmetric.
    The target object will be made symmetric to the anchor object.
