# ActuatorRelativeTo

## Overview

ActuatorRelativeTo is an Enum specifies the reference coordinatate system in which a physical Constraint operates.

This is used as a RelativeTo property in constraint classes such as LinearVelocity, AngularVelocity, and VectorForce and determines which coordinate system the vector values (velocity, force, angular velocity) are to be interpreted relative to.
