Back to top Toggle Light / Dark / Auto color theme Toggle table of contents sidebar Armature Operators ¶ bpy.ops.armature. align ( ) ¶ Align selected bones to the active bone (or to their parent) bpy.ops.armature. assign_to_collection ( * , collection_index = -1 , new_collection_name = '' ) ¶ Assign all selected bones to a collection, or unassign them, depending on whether the active bone is already assigned or not Parameters : collection_index ( int in [ -1 , inf ] , ( optional ) ) – Collection Index, Index of the collection to assign selected bones to. When the operator should create a new bone collection, use new_collection_name to define the collection name, and set this parameter to the parent index of the new bone collection new_collection_name ( string , ( optional , never None ) ) – Name, Name of a to-be-added bone collection. Only pass this if you want to create a new bone collection and assign the selected bones to it. To assign to an existing collection, do not include this parameter and use collection_index bpy.ops.armature. autoside_names ( * , type = 'XAXIS' ) ¶ Automatically renames the selected bones according to which side of the target axis they fall on Parameters : type (enum in [ 'XAXIS' , 'YAXIS' , 'ZAXIS' ], (optional)) – Axis, Axis to tag names with XAXIS X-Axis – Left/Right. YAXIS Y-Axis – Front/Back. ZAXIS Z-Axis – Top/Bottom. bpy.ops.armature. bone_primitive_add ( * , name = '' ) ¶ Add a new bone located at the 3D cursor Parameters : name ( string , ( optional , never None ) ) – Name, Name of the newly created bone bpy.ops.armature. calculate_roll ( * , type = 'POS_X' , axis_flip = False , axis_only = False ) ¶ Automatically fix alignment of select bones’ axes Parameters : type (enum in [ 'POS_X' , 'POS_Z' , 'GLOBAL_POS_X' , 'GLOBAL_POS_Y' , 'GLOBAL_POS_Z' , 'NEG_X' , 'NEG_Z' , 'GLOBAL_NEG_X' , 'GLOBAL_NEG_Y' , 'GLOBAL_NEG_Z' , 'ACTIVE' , 'VIEW' , 'CURSOR' ], (optional)) – Type axis_flip ( boolean , ( optional ) ) – Flip Axis, Negate the alignment axis axis_only ( boolean , ( optional ) ) – Shortest Rotation, Ignore the axis direction, use the shortest rotation to align bpy.ops.armature. click_extrude ( ) ¶ Create a new bone going from the last selected joint to the mouse position bpy.ops.armature. collection_add ( ) ¶ Add a new bone collection bpy.ops.armature. collection_assign ( * , name = '' ) ¶ Add selected bones to the chosen bone collection Parameters : name ( string , ( optional , never None ) ) – Bone Collection, Name of the bone collection to assign this bone to; empty to assign to the active bone collection bpy.ops.armature. collection_create_and_assign ( * , name = '' ) ¶ Create a new bone collection and assign all selected bones Parameters : name ( string , ( optional , never None ) ) – Bone Collection, Name of the bone collection to create bpy.ops.armature. collection_deselect ( ) ¶ Deselect bones of active Bone Collection bpy.ops.armature. collection_move ( * , direction = 'UP' ) ¶ Change position of active Bone Collection in list of Bone collections Parameters : direction (enum in [ 'UP' , 'DOWN' ], (optional)) – Direction, Direction to move the active Bone Collection towards bpy.ops.armature. collection_remove ( ) ¶ Remove the active bone collection bpy.ops.armature. collection_remove_unused ( ) ¶ Remove all bone collections that have neither bones nor children. This is done recursively, so bone collections that only have unused children are also removed File : startup/bl_operators/anim.py:617 bpy.ops.armature. collection_select ( ) ¶ Select bones in active Bone Collection bpy.ops.armature. collection_show_all ( ) ¶ Show all bone collections File : startup/bl_operators/anim.py:572 bpy.ops.armature. collection_unassign ( * , name = '' ) ¶ Remove selected bones from the active bone collection Parameters : name ( string , ( optional , never None ) ) – Bone Collection, Name of the bone collection to unassign this bone from; empty to unassign from the active bone collection bpy.ops.armature. collection_unassign_named ( * , name = '' , bone_name = '' ) ¶ Unassign the named bone from this bone collection Parameters : name ( string , ( optional , never None ) ) – Bone Collection, Name of the bone collection to unassign this bone from; empty to unassign from the active bone collection bone_name ( string , ( optional , never None ) ) – Bone Name, Name of the bone to unassign from the collection; empty to use the active bone bpy.ops.armature. collection_unsolo_all ( ) ¶ Clear the ‘solo’ setting on all bone collections File : startup/bl_operators/anim.p
