Mirror Feature PropertyManager

Use the Mirror Feature PropertyManager to mirror features. In parts, you can mirror faces, features, and bodies. In assemblies, you can mirror assembly features.

To open this PropertyManager:

  • In a part, click Mirror (Features toolbar) or Insert > Pattern/Mirror > Mirror.
  • In an assembly, click Assembly Features (Assembly tab on the CommandManager) and click Mirror , or click Insert > Assembly Feature > Mirror.

Mirror Face/Plane

(Available in parts and assemblies.)

Mirror Face/Plane Specifies the plane to mirror about.

Select a plane or planar face.

Secondary Mirror Face/Plane

Available in parts only. You can mirror an item about two planes at a time in one feature. Select planes or planar faces.

Secondary Mirror Face/Plane Specifies a secondary plane to mirror about in addition to the first plane.
  Mirror seed only Available if the secondary plane is perpendicular to the first plane.
Perpendicular planes Mirror seed only selected Mirror seed only cleared

Features to Mirror

(Available in parts and assemblies.)

Features to Mirror Specifies the features to mirror.

Select one or more features.

Faces to Mirror

(Available only in parts.) Useful with imported models where only the faces that make up the feature were imported, and not the feature itself.

Faces to Mirror Specifies the faces to mirror.

In the graphics area, select the faces that make up the feature you want to mirror.

Bodies to Mirror

(Available only in parts.)

Solid/Surface Bodies to Mirror Specifies the solid bodies and surface bodies to mirror.

Select one or more bodies.


  Geometry Pattern Mirrors only the geometry (faces and edges) of the features, rather than solving the whole feature.
You must select this option when, in a multibody part, you mirror features of one body onto another body.

The geometry pattern option speeds up the creation and rebuilding of the feature. However, you cannot create geometry patterns of features that have faces merged with the rest of the part.

  Merge solids (Available when mirroring solid bodies.) Merges the seed and mirrored solid bodies into one solid body.
  Knit surfaces (Available when mirroring surface bodies.) Merges the seed and mirrored surface bodies into one surface body.
  Propagate visual properties Mirrors the visual properties (such as colors, textures, and cosmetic thread data) of the seed item to the mirrored item.

Feature Scope

  • For multibody parts, see Feature Scope in Multibody Parts.
  • For assemblies, see Feature Scope in Assemblies.
