Add a Symmetry Constraint

General

  • Symmetry is always defined with respect to a planar surface.
  • The elements that are desired to be symmetric are clicked first, followed by the symmetry plane.

Add a symmetry constraint between parts

  1. Select Assembly | Constraints | Add symmetry constraint.
  2. Select a face, line, or a point from the first part.
  3. Select a face, line, or a point the second part.
  4. Select the symmetry plane from the third part.
    • The symmetry plane can also be an auxiliary plane.
    • The parts will be positioned in accordance with the constraint.
  5. Continue repeating steps 1 ... 4 until all the desired constraints have been added.
  6. Stop adding symmetry constraints:
    • Select another function.
    • Press the Esc key.
    • Press the V key (Confirm).
    • Select the context-sensitive function OK.
    • Click the middle mouse button.
Note:
  • You can also use this function by first selecting the two parts, and then
    • The ribbon bar function Add symmetry constraint or
    • The context-sensitive function Constraints > Symmetry.
    • Select the second part Ctrl+left mouse button.
  • You can define a constraint as configuration-specific by selecting the constraint and then selecting the context-sensitive menu function Edit.

    Edit Constraint

  • Zoom the part view by the Z key to select an element. Zoom all by pressing the A key.
  • Move a part by moving the cursor onto a part, then moving the mouse while holding down the left mouse button.
