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.

Importante

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

Target

Data ID used to select the constraint’s target, and is not functional (red state) when it has none.

Distance

This number field sets the limit distance, i.e. the radius of the constraining sphere.

Reset Distance

When clicked, this small button will reset 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.

For Transform

Transform operators will take the constraint into account to immediately restrict the resulting transform property values.
