Limit Distance Constraint

The Limit Distance constraint forces an object or bone to stay further from, nearer to, or exactly at a given distance from a target. In other words, the owner’s location is constrained to be either outside, inside, or on the surface of a sphere centered on the target.

Important

This constraint has no effect on connected bones as their position is determined by their parent bone.

Limit Distance constraint.

Target

The object or bone to stay close to/keep away from.

Distance

The limit distance, i.e. the radius of the constraining sphere. It’s calculated automatically when selecting the first target.

(Reset Distance)

Set the Distance to the current distance between owner and target.

Clamp Region

How to constrain the owner relative to the spherical boundary:

Inside:

Keep the owner trapped within the sphere.

Outside:

Prevent the owner from entering the sphere.

On Surface:

Constrain the owner to the surface of the sphere.

Affect Transform

When the owner is manually moved around, restrict not just its visual position but also its Location in the Properties Editor’s Transform panel.

Target/Owner

The spaces for retrieving the position of the target and for applying the constrained result to the owner.

Influence

How strongly the constraint affects the owner.

Tip

Evaluating both owner and target in a Custom Space will automatically scale the Distance according to the scale of the space’s object/bone.
