Armature ‣ Symmetrize

This operator will mirror the selected bones along the X axis based on Blender’s bone naming convention for symmetrical armatures, either from left to right or right to left, depending on the selection.

Note

If the side of the bone cannot be determined, it will be ignored.

Bones with the opposite names that don’t yet exist will be created, and already existing ones will be overwritten. If matching bones are selected on both sides, mirroring will happen from right to left.

Symmetrized bone and constraint properties will have the necessary changes to mirror their behaviors. When symmetrizing bones with Action Constraints, the necessary keyframes will be added to the target Action to result in symmetrical movement when the Action is activated.

Note

Note that bone or constraint drivers will not be created or affected in any way.

Bone collection assignments are also symmetrized. Similar to bones, only collections that follow the naming convention are symmetrized. Collections are created if they don’t exist yet. On creation, they will be parented to the same collection as the collection from which they are symmetrized.

Note

Blender does not care if a left bone is assigned to a right collection. It will symmetrize regardless meaning the resulting right bone will be assigned to a left collection.
