+## Properties

+A Part object comes with the following properties:
+
+- `attributes` : An [Attributes](/reference/api/attributes) instance holding
+  the part's attributes
+- `hidden` : When this is `true` the part will be hidden (excluded it from the
+  output).  See [Part.hide()](/reference/api/part/hide),
+  [Part.unhide()](/reference/api/part/unhide), and
+  [Part.setHidden()](/reference/api/part/sethidden) for various methods that
+  allow setting this in a chainable way.
+- `name` : The name of the part
+- `paths` : Holds the paths used in the part
+- `points` : Holds the points used in the part
+- `snippets` : Holds the snippets used in the part
