# Bridge Constraint

## Intro#

Connect Shapes together to form chains or bridge structures.

## UI#

Stretch - Determine how much the Constraint stretches. A higher value will result in more elastic looking result.

Frequency (Hz) - A higher value will give the spring more bounce.

Damping Ratio - A higher value will bring the spring to a rest more quickly.

Breakable - When enabled, the Constraint can be broken by other forces.

Breaking Force - Set the amount of force required to break the Constraint.

• Pinned Index - Set the index to be pinned. The strings first or last can be used to dynamically set the first and last Id when using a Sub-Mesh (e.g. Duplicator) as a Body. Alternatively, entering values here will pin the corresponding Id.
• Rotational Limits - Set an upper (U) and lower (L) angle to clamp the Constraint's rotation.
