Copy Scale Constraint

Description

The Copy Scale constraint forces its owner to have the same scale as its target.

Here we talk of scale, not of size! Indeed, you can have two objects, one much bigger than the other, and yet both of them have the same scale. This is also true with bones: in Pose mode, they all have a unitary scale when they are in rest position, represented by their visible length.

Options

Copy Scale panel

Target

This constraint uses one target, and is not functional (red state) when it has none.

Bone

If Target is an Armature, a new field is displayed offering the optional choice to set an individual bone as Target.

Head/Tail

If a Bone is set as Target, a new field is displayed offering the optional choice of where along this bone the target point lies.

Vertex Group

If Target is a Mesh, a new field is displayed offering the optional choice to set a Vertex Group as target.

X, Y, Z

These buttons control along which axes the scale is constrained – by default, it is enabled along all three.

Offset

When enabled, this control allows the owner to be scaled (using its current transform properties), relatively to its target’s scale.

Space

This constraint allows you to choose in which space to evaluate its owner’s and target’s transform properties.
