Controls on the Fin Adjustment Tools rollout are for adjusting some aspects of bone geometry, including fins.
Sets the fin parameters as absolute values. Use this option to set the same fin values for all selected bones.
Sets the fin parameters relative to their current values. Use this option to retain size relationships between bones with different-sized fins.
Copies the bone and fin settings for the currently selected bone, in preparation for pasting to another bone.
Pastes the copied bone and fin settings to the currently selected bone.
Sets the width of the bone.
