The **grainline** plugin provides [the grainline macro](/reference/macros/grainline/):

<Example part="plugin_grainline" caption="An example of the grainline macro" design={false} />

```js
let { Point, points, macro } = part.shorthand();

points.grainlineFrom = new Point(10, 10);
points.grainlineTo = new Point(100, 10);

macro("grainline", {
  from: points.grainlineFrom,
  to: points.grainlineTo
});
```

<Tip>

The grainline plugin is part of our [plugin-bundle](/reference/plugins/bundle)

</Tip>

## Installation

```bash
npm install @freesewing/plugin-grainline
```

## Usage

Like all [build-time plugins](/guides/plugins/#build-time-plugins), you load them 
by passing them to the [`freesewing.Design`](/reference/api#design) constructor:

```js
import freesewing from "@freesewing/core";
import grainline from "@freesewing/plugin-grainline";
import config from "../config";

const Pattern = new freesewing.Design(config, grainline);
```

Now you can use [the grainline macro](/reference/macros/grainline) in your parts.
