Make elements symmetric in a 3D sketch


When creating a 3D sketch in a model document, you can use the Symmetric command to make two or more elements symmetrical around a reference plane.

  1. On the 3D Sketching tab, choose the 3D Relate group→Symmetric command .

    The command is also available on the Home tab in an assembly 3D sketch.

  2. Click a reference plane to use as a symmetry axis.

    You can use QuickPick to easily select the YZ reference plane shown in this example.

  3. Click the first element that you want to make symmetric. You can click a line, arc, or circle of a 3D Sketch.

  4. Click a second element. The first element will be made symmetric to the second element.

    • You can click a line, arc, or circle in a 2D sketch or a 3D sketch.

    • You can click a linear edge, arc edge, or circular edge on a 3D model.

    The first element is symmetrically aligned with the second element about the reference plane, and the symmetric relationship handle is displayed on both elements.

Tip:

If you drag the edit handle to change the diameter of one of the elements where a symmetric relationship is applied, both elements are sized together.
