Example

```js ({ Point, points, Path, paths, Snippet, snippets, utils, part }) => {

points.A = new Point(10, 10) points.B = new Point(90, 30)

paths.AB = new Path().move(points.A).line(points.B)

snippets.x = new Snippet( "notch", utils.beamIntersectsX(points.A, points.B, 40) )

paths.help = new Path() .move(new Point(40, 5)) .line(new Point(40, 35)) .addClass("note dashed")

return part }
