title description
Rod RodConstraint keeps two attachments separated by a defined length, with optional limits on rotational tilt.
For an overview on creating, visualizing, and simulating mechanical constraints, including `Class.RodConstraint`, see [Mechanical constraints](../../physics/mechanical-constraints.md). Also see [Roblox units](../../physics/units.md) to understand how Roblox units compare to metric units.

A Class.RodConstraint keeps two attachments separated by its defined Class.RodConstraint.Length|Length. By default, both attachments can rotate freely, although you can enable limits to restrict rotational tilt.

Limits

You can limit rotation of the attachments within a cone, independently of each other, by enabling the Class.RodConstraint.LimitsEnabled|LimitsEnabled property and setting Class.RodConstraint.LimitAngle0|LimitAngle0 and Class.RodConstraint.LimitAngle1|LimitAngle1 respectively.
