+title: Path
+---
+
+A path represents an SVG path, which are the lines and curves on our pattern.
+
+## Signature
+
+```js
+Path new Path()
+```
+
+The Path constructor takes no arguments.
+
+## Properties
+
+A Path object comes with the following properties:
+
+- `attributes` : An [Attributes](/reference/api/attributes) instance holding
+  the path's attributes
+- `hidden` : When this is `true` the path will be hidden (excluding it from the
+  output).  See [Path.hide()](/reference/api/path/hide),
+  [Path.unhide()](/reference/api/path/unhide), and
+  [Path.setHidden()](/reference/api/path/sethidden) for various methods that
+  allow setting this in a chainable way.
+
+:::note RELATED
+See [Using Attributes](/howtos/code/attributes)
+for information about custom Attributes that can be used with Paths.
