name: RotationOrder
type: enum
summary: |
  The order of rotation axes used for Euler angles encoding of rotations.
description: |
  Euler angles encode a rotation in 3D space via a sequence of three rotations
  along the X, Y, and Z axes. The `RotationOrder` enum specifies the order in
  which the engine performs these rotations.

  To help visualize the many rotation orders, you can test them manually in
  Studio with the [Rotate](../../../parts#rotate) tool or by inserting
  `Library.task.wait()` statements between individual rotations of a cube with a
  unique face:

  ```lua
  local Workspace = game:GetService("Workspace")

  local cube = Workspace.Cube
  local rx, ry, rz = math.rad(90), math.rad(90), math.rad(90)

  task.wait(5)
  cube.CFrame *= CFrame.fromEulerAngles(rx, 0, 0)  -- X
  task.wait(5)
  cube.CFrame *= CFrame.fromEulerAngles(0, ry, 0)  -- Y
  task.wait(5)
  cube.CFrame *= CFrame.fromEulerAngles(0, 0, rz)  -- Z
  ```

  An equivalent operation is:

  ```lua
  local Workspace = game:GetService("Workspace")

  local cube = Workspace.Cube
  local rx, ry, rz = math.rad(90), math.rad(90), math.rad(90)

  cube.CFrame = CFrame.fromEulerAngles(rx, ry, rz, Enum.RotationOrder.XYZ)
  ```
