The replaces the NextJS site powering FreeSewing.dev with a Docusaurus
setup. It's part of my efforts to simplify FreeSewing's setup so we can
focus on our core value proposition.

+title: Point.clone()
+---
+
+The `Point.clone()` method returns a new `Point` with the same coordinates and
+attributes as the original point.
+
+## Signature
+
+```js
+Point point.clone()
+```
+
+:::tipThis method is chainable as it returns the `Point` object:::
+
+## Example
+
+<Example caption="An example of the Point.clone() method">
+```js
+({ Point, points, Path, paths, Snippet, snippets, part }) => {
+
+  points.A = new Point(25, 25)
+    .setText("Point A", "text-xl")
+    .attr("data-text-fill-opacity", "0.5")
+  points.B = points.A.clone().setText("Point B")
+
+  snippets.x = new Snippet("notch", points.A)
+
+  // Avoid the text getting cropped
+  paths.hidden = new Path()
+    .move(new Point(20,10))
+    .move(new Point(75,30))
+    .addClass('hidden')
+
+  return part
+}
+```
+</Example>
+
+
+## Notes
+
+The [`Point.copy()`](/reference/api/point/copy/) method will only copy the
+point's coordinates, whereas this `Point.clone()` method will also copy its
+attributes.
