Symmetry¶

Snap to Symmetry¶

Reference

Mode: Edit Mode

Menu: Mesh ‣ Snap to Symmetry

The Snap to Symmetry tool lets you snap a meshes vertices to their mirrored neighbors.

Useful when dealing with meshes which are mostly symmetrical, but have vertices which have been moved enough that Blender does not detect then as mirrored (when x-mirror option is enable for example).

This can be caused by accident when editing without x-mirror enabled. Sometimes models imported from other applications are asymmetrical enough that mirror fails too.

Direction: Specify the axis and direction to snap. Can be any of the three axes, and either positive to negative, or negative to positive.
Threshold: Specify the search radius to use when finding matching vertices.
Factor: Support for blending mirrored locations from one side to the other (0.5 is an equal mix of both).
Center: Snap vertices in the center axis to zero.

Symmetrize¶

Reference

Mode: Edit Mode

Menu: Mesh ‣ Symmetrize

The Symmetrize tool is a quick way to make a mesh symmetrical. Symmetrize works by cutting the mesh at the pivot point of the object, and mirroring over the geometry in the specified axis, and merges the two halves together (if they are connected). Also the mesh data is copied from one side to the other: e.g. UVs, vertex colors, vertex weights.

Direction: Specify the axis and direction of the effect. Can be any of the three axes, and either positive to negative, or negative to positive.
Threshold: ToDo.
