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

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

```js
points.topLeft = new Point(0, 0);
points.bottomLeft = new Point(0, 30);
points.topRight = new Point(100, 0);
points.bottomRight = new Point(100, 30);

paths.demo = new Path()
  .move(points.topLeft)
  .line(points.bottomLeft)
  .line(points.bottomRight)
  .line(points.topRight)
  .close()
  .attr("class", "note dashed");

macro("round", {
  from: points.topLeft,
  to: points.bottomRight,
  via: points.bottomLeft,
  radius: 10,
  prefix: 'bl',
  render: true
});
macro("round", {
  from: points.bottomRight,
  to: points.topLeft,
  via: points.topRight,
  radius: 20,
  prefix: 'tr',
  render: true
});
```

<Tip>

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

</Tip>

## Installation

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

## 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 round from "@freesewing/plugin-round";
import config from "../config";

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

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

<Warning>

The round macro is intended for rounding 90° angles
