Add a Symmetry Constraint

General

• A symmetry constraint can be set to lines, points and sketch planes.
• The symmetry plane is selected as the last element.

Add a symmetry constraint to a 3D sketch

1. Select Sketch | Constraints | Add symmetry constraint or
   • select the context-sensitive function Constraints > Concentric
2. Select the first line, point, or sketch plane.
3. Select the second line, point, or sketch plane.
4. Select the symmetry plane or planar surface.
   • The second selected line or point moves so that it is symmetrical with the first line or point with respect to the symmetry plane.
5. Repeat steps 2 to 4 to add new symmetry constraints
6. Stop adding symmetry constraints
