Mirror reference

In the Mirror dialog, you can create a copy of selected faces, bodies, features, or components, mirrored across a plane in Fusion.

Design > Solid or Surface > Create > Mirror

Type (Parametric Modeling mode only)

Select the type of objects you want to mirror.

• Faces: Mirrors faces across a plane.
• Bodies: Mirrors bodies across a plane.
• Features: Mirrors timeline features across a plane.
• Components: Mirrors components across a plane.

Objects

Select objects to mirror.

Mirror Plane

Select a plane or planar face to mirror objects across.

Operation (Parametric Modeling mode only)

Select whether to create a new body or join the mirrored body with the original body.

• New Body: Creates a new body mirrored across the mirror plane.
• Join: Joins the mirrored body with the original body, if they intersect. Solid bodies are combined. Surface bodies are stitched.

Tolerance (Surfaces only)

Specify stitch tolerance when joining surface bodies.

Compute Option (Features type only)

Select a calculation method to compute the mirror operation for the selected features.

• Optimized: Creates identical copies of features by patterning feature faces. Optimized is the fastest compute method.
  • Cannot create overlapping occurrences
  • Cannot create occurrences that intersect faces other than the faces of the original feature
  • Can speed up pattern compute time
• Identical: Creates identical copies of features by replicating the results of original features.
  • Use this for identical features when the Optimized method is not available.
• Adjust: Creates potentially differing copies of features by patterning features and calculating extents or terminations of each occurrence individually.
  • Computation time is lengthy for patterns with large numbers of occurrences.
  • Preserves design intent by allowing occurrences to adjust based on feature extent or termination conditions, like a feature that terminates on a face.
  • Not available for solid bodies in an open or surface state.
  • If Adjust encounters a planar face, the operation terminates. The result is a feature with a size and shape different from the original.
