### *class* RAMotionFrameSource

Rocky PrePost Scripting wrapper for the root element for Motion Frames

This class represents the “Motion Frame” item on the project’s data tree. Get the [`RAMotionFrameSource`](#generated.RAMotionFrameSource)from a [`RAStudy`](RAStudy.md#generated.RAStudy) via:

```python
motion_frame_source = study.GetMotionFrameSource()

```

This is the element through which motion frames with no parent frames can be created, and through which all motion frames can be directly accessed:

```python
motion_frame_1 = motion_frame_source.NewFrame()
motion_frame_2 = motion_frame.GetMotionFrame('My Frame')
for motion_frame in motion_frame.IterMotionFrames():
    motion_frame.SetRelativePosition([1.0, 2.0, 3.0], 'm')

```

**Methods:**

NameDescription[`GetMotionFrame`](#generated.RAMotionFrameSource.GetMotionFrame)(frame\_name)Get a specific motion frame given its name.[`GetParentMotionFrame`](#generated.RAMotionFrameSource.GetParentMotionFrame)()Gets the parent motion frame.[`IterMotionFrames`](#generated.RAMotionFrameSource.IterMotionFrames)()Iterates over all the motion frames available (recursively).[`NewConeCrusherFrame`](#generated.RAMotionFrameSource.NewConeCrusherFrame)()Creates a new cone crusher frame.[`NewFrame`](#generated.RAMotionFrameSource.NewFrame)()Creates a new motion frame.[`RemoveFrame`](#generated.RAMotionFrameSource.RemoveFrame)(motion\_frame)Removes a previously-created motion frame.<a id="generated.RAMotionFrameSource.GetMotionFrame"></a>

#### GetMotionFrame(frame\_name)

Get a specific motion frame given its name.

- **Parameters:****frame\_name** (*unicode*) –
- **Return type:**[RAMotionFrame](RAMotionFrame.md#generated.RAMotionFrame)

<a id="generated.RAMotionFrameSource.GetParentMotionFrame"></a>

#### GetParentMotionFrame()

Gets the parent motion frame. If the Motion Frame is a RAMotionFrameSource it returns None.

- **Return type:**[RAMotionFrame](RAMotionFrame.md#generated.RAMotionFrame)

<a id="generated.RAMotionFrameSource.IterMotionFrames"></a>

#### IterMotionFrames()

Iterates over all the motion frames available (recursively).

- **Return iter(RAMotionFrame):**

<a id="generated.RAMotionFrameSource.NewConeCrusherFrame"></a>

#### NewConeCrusherFrame()

Creates a new cone crusher frame.

- **Return type:**[RAConeCrusherFrame](RAConeCrusherFrame.md#generated.RAConeCrusherFrame)

<a id="generated.RAMotionFrameSource.NewFrame"></a>

#### NewFrame()

Creates a new motion frame.

<a id="generated.RAMotionFrameSource.RemoveFrame"></a>

#### RemoveFrame(motion\_frame)

Removes a previously-created motion frame.

- **Parameters:****motion\_frame** ([*RAMotionFrame*](RAMotionFrame.md#generated.RAMotionFrame) *or* [*RAConeCrusherFrame*](RAConeCrusherFrame.md#generated.RAConeCrusherFrame)) –
