+
+A Stack object represents a layer within a pattern, holding one or
+more parts..
+
+<Related>
+
+See [Stacks](/guides/patterns/stacks)
+for information about how stacks are used in a pattern
+
+</Related>
+
+## Signature
+
+```js
+Stack new Stack(String name)
+```
+
+The stack constructor takes a single argument, a String containing the name
+of the stack.
+
+## Properties
+
+Stack objects come with the following properties:
+
+- `attributes` : An [Attributes](/reference/api/attributes) instance holding the point's attributes
+- `parts` : A set of parts in the stack
+- `name` : The name of the stack
+- `topleft` : A [Point](/reference/api/point) that is the top left of the stack's bounding box
+- `bottomRight` : A [Point](/reference/api/point) that is the bottom right of the stack's bounding box
+- `width` : The width of the stack in mm
+- `height` : The height of the stack in mm
+- `anchor` : A [Point](/reference/api/point) that is used as the anchor to align parts in the stack
+
+
+## Example
+
+<Example caption="Example of the Stack constructor">
+```js
+import { Stack } from '@freesewing/core'
+
+const myStack = new Stack('mystack')
+```
+</Example>

+## Stack.generateTransform() signature
+
+```js
+Stack stack.generateTransforms(Object transforms)

+to apply:
+
+| Property | Type |Description |
+|----------|------|------------|
+| `move`   | Object | `move.x` and `move.y` are coordinates to which the stack should be translated
+| `rotate` | Number | The number of degrees to rate the stack around its center |

+| `flipY`  | Boolean | Whether to flip the stack along the Y axis |
