Setting Up a Mirror Relationship

  1. Click the Mirror tool in the Create ribbon group.
  2. Click the Setup Mirror tool guide. As you mouse over the faces in your design, the eligible faces are highlighted. A face is eligible if it is symmetrical to another face in your design.
  3. Click a face.
  4. Click a parallel face.The second face is highlighted in blue and the mirror plane appears halfway between the two faces. Edits to one face will now be mirrored on the other face. Geometry in between the two faces will be updated accordingly.

You can create mirror relationships by finding similar faces on the other side of an existing mirror.
