Snippets
Snippets are little embellishments you can use and re-use on your pattern. They are typically used for things like logos or buttons.
Each snippet must have:
- An anchor point that determine where the snippet will be located
- The name of the snippet to insert
- Preview
- Code
- X-Ray

Since our example image does not have any snippets in it, here's an example
of a button
snippet:
- Preview
- Code
- X-Ray
({ Point, Path, paths, Snippet, snippets, part }) => {
snippets.demo = new Snippet('button', new Point(0,0))
// Prevent clipping
paths.diag = new Path()
.move(new Point(-50,-4))
.move(new Point(50,4))
return part
}
