Creating Symmetry

You can modify a curve or a patch by symmetrizing it to a plane with a symmetry condition up to G3.

This task shows you how to:

Match a Patch to a Symmetry Plane

You can match a patch to a symmetry plane.

Before you begin: Open a 3DShape containing a patch and, additionally, a plane, if desired.
  1. Select a patch edge.
  2. Do one of the following:
    • Use the default symmetry plane (y=0). In this case, you don not need to select anything.
    • Select a plane, for example an OmniPlane.

  3. From the Surfacing section of the action bar, click Symmetry .
    The patch is matched to the symmetry plane with G2 continuity.

  4. In the Transform section of the Sculpt panel, click Activate Transform , and select the plane.
  5. Manipulate the plane using the Robot.
    The matching is updated interactively.

  6. Click OK in the Symmetry panel.
    Symmetry.Condtion.x is created in the tree.
  7. Optional: Double-click Symmetry.Condition.x in the tree or the symmetry label in the work area to edit the symmetry condition at any time.

    To show the labels, click in the Conditions section of the Sculpt panel.

Match a Curve to a Symmetry Plane

You can match a curve to a symmetry plane, to obtain a G2 matching the mirrored geometry, for example.

Before you begin: Open a 3DShape containing a curve.
  1. Click Both in the V-Nav options bar to display both original and mirrored geometry.
  2. Select a curve near an endpoint.

  3. Click Symmetry .

    The curve is matched to the default symmetry plane (y=0) with G2 continuity.
