Point | false utils.beamsIntersect(
  Point A,

```js
let {
  Point,
  points,
  Path,
  paths,
  Snippet,
  snippets,
  utils
} = part.shorthand();

points.A = new Point(10, 10);
points.B = new Point(50, 40);
points.C = new Point(45, 20);
points.D = new Point(60, 15);

paths.AB = new Path().move(points.A).line(points.B);
paths.CD = new Path().move(points.C).line(points.D);

snippets.x = new Snippet(
  "notch",
  utils.beamsIntersect(points.A, points.B, points.C, points.D)
);
