Limit Distance Constraint¶
The Limit Distance constraint forces its owner to stay either further from, nearer to, or exactly at a given distance from its target. In other words, the owner’s location is constrained either outside, inside, or at the surface of a sphere centered on its target.
When you specify a (new) target, the Distance value is automatically set to correspond to the distance between the owner and this target.

Note that if you use such a constraint on a connected bone, it will have no effect, as it is the parent’s tip which controls the position of your owner bone’s root.
Options¶
Limit Distance panel.¶
- Target
Data ID used to select the constraint’s target, and is not functional (red state) when it has none. See common constraint properties for more information.
- Distance
This number field sets the limit distance, i.e. the radius of the constraining sphere.
- (Reset Distance)
Resets the Distance value,so that it corresponds to the actual distance between the owner and its target (i.e. the distance before this constraint is applied).
- Clamp Region
The Limit Mode select menu allows you to choose how to use the sphere defined by the Distance setting and target’s origin:
- Inside
The owner is constrained inside the sphere.
- Outside
The owner is constrained outside the sphere.
- Surface
The owner is constrained on the surface of the sphere.
- Affect Transform
Transform operators will take the constraint into account to immediately restrict the resulting transform property values.
- Target/Owner
Standard conversion between spaces. See common constraint properties for more information.
- Influence
Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
Tips
Evaluating both owner and target in a Custom Space using the root bone or any other suitable parent bone will automatically scale the effective distance with the relevant part of the rig.
