base classes — [`bpy_struct`](bpy.types.bpy_struct.html#bpy.types.bpy_struct "bpy.types.bpy_struct"), [`Constraint`](bpy.types.Constraint.html#bpy.types.Constraint "bpy.types.Constraint")

*class* bpy.types.CopyTransformsConstraint(*Constraint*)
:   Copy all the transforms of the target

    head_tail
    :   Target along length of bone: Head is 0, Tail is 1

        Type:
        :   float in [0, 1], default 0.0

    mix_mode
    :   Specify how the copied and existing transformations are combined

        - `REPLACE`
          Replace – Replace the original transformation with copied.
        - `BEFORE_FULL`
          Before Original (Full) – Apply copied transformation before original, using simple matrix multiplication as if the constraint target is a parent in Full Inherit Scale mode. Will create shear when combining rotation and non-uniform scale..
        - `BEFORE`
          Before Original (Aligned) – Apply copied transformation before original, as if the constraint target is a parent in Aligned Inherit Scale mode. This effectively uses Full for location and Split Channels for rotation and scale..
        - `BEFORE_SPLIT`
          Before Original (Split Channels) – Apply copied transformation before original, handling location, rotation and scale separately, similar to a sequence of three Copy constraints.
        - `AFTER_FULL`
          After Original (Full) – Apply copied transformation after original, using simple matrix multiplication as if the constraint target is a child in Full Inherit Scale mode. Will create shear when combining rotation and non-uniform scale..
        - `AFTER`
          After Original (Aligned) – Apply copied transformation after original, as if the constraint target is a child in Aligned Inherit Scale mode. This effectively uses Full for location and Split Channels for rotation and scale..
        - `AFTER_SPLIT`
          After Original (Split Channels) – Apply copied transformation after original, handling location, rotation and scale separately, similar to a sequence of three Copy constraints.

        Type:
        :   enum in [`'REPLACE'`, `'BEFORE_FULL'`, `'BEFORE'`, `'BEFORE_SPLIT'`, `'AFTER_FULL'`, `'AFTER'`, `'AFTER_SPLIT'`], default `'REPLACE'`

    remove_target_shear
    :   Remove shear from the target transformation before combining

        Type:
        :   boolean, default False

    subtarget
    :   Armature bone, mesh or lattice vertex group, …

        Type:
        :   string, default “”, (never None)

    target
    :   Target object

        Type:
        :   [`Object`](bpy.types.Object.html#bpy.types.Object "bpy.types.Object")

    use_bbone_shape
    :   Follow shape of B-Bone segments when calculating Head/Tail position

        Type:
        :   boolean, default False

    *classmethod* bl_rna_get_subclass(*id*, *default=None*, */*)
    :   Parameters:
        :   **id** (*str*) – The RNA type identifier.

        Returns:
        :   The RNA type or default when not found.

        Return type:
        :   [`bpy.types.Struct`](bpy.types.Struct.html#bpy.types.Struct "bpy.types.Struct") subclass

    *classmethod* bl_rna_get_subclass_py(*id*, *default=None*, */*)
    :   Parameters:
        :   **id** (*str*) – The RNA type identifier.

        Returns:
        :   The class or default when not found.

        Return type:
        :   type
