Planar Symmetry

Create a symmetric copies of selected objects across a symmetry plane.

  1. On the ribbon, click the Modify tab.
  2. In the Symmetry group, click the Planar Symmetry icon.

  3. Click one or more objects, and then right-click to confirm.
  4. Optional: To define the symmetry plane, in the guide bar, select one of the following options:
    • X (default): Orient the symmetry plane along the x-y plane.
    • Y: Orient the symmetry plane along the y-z plane.
    • Z: Orient the symmetry plane along the z-x plane.
    • Ref geometry: You can align the symmetry plane with reference geometry by clicking another object in the scene.
    • Custom: You can define a custom symmetry plane by doing the following:
      1. Move the symmetry plane by dragging the Move Symmetry Plane arrow.
        Tip: To snap to the closest axis, hold down Shift while dragging.
      2. Move the origin. This changes the distance between the source objects and the symmetric copies.
        • Drag the origin point.
        • Click the origin point, and then enter the x, y, and z coordinates.
      3. Rotate the symmetry plane:
        • Drag the Plane Normal point or a rotation arrow.
        • Click a rotation arrow, and then enter a Degree.
  5. Optional: To trim the intersections when a source object and a copy intersect, in the guide bar, click Trim objects.
    Note: The source object is not trimmed; it is used to trim a copy.
  6. Optional: To combine the source objects with the symmetric copies, in the guide bar, click Combine with inputs.
    Note: The source objects can be edited in the construction history, but they will no longer be listed in the Model Browser.
  7. Right-click and mouse through the check mark to exit, or double-right-click.
