# Sandbox.FixedJointBuilder

Builds a fixed joint that locks the relative position and rotation of two bodies.

- Kind: class
- Namespace: `Sandbox`
- Assembly: `Sandbox.Engine`
- Inherits: [Sandbox.PhysicsJointBuilder](/api/Sandbox.PhysicsJointBuilder)
- Modifiers: sealed

## Properties

- [`AngularDamping`](/api/Sandbox.FixedJointBuilder/AngularDamping): The damping ratio for the joint's angular spring. Higher values reduce oscillation in rotation.
- [`AngularFrequency`](/api/Sandbox.FixedJointBuilder/AngularFrequency): The frequency of the joint's angular spring in hertz. Higher values make the joint stiffer in rotation.
- [`LinearDamping`](/api/Sandbox.FixedJointBuilder/LinearDamping): The damping ratio for the joint's linear spring. Higher values reduce oscillation in translation.
- [`LinearFrequency`](/api/Sandbox.FixedJointBuilder/LinearFrequency): The frequency of the joint's linear spring in hertz. Higher values make the joint stiffer in translation.
