The `rmd` macro removes a dimension.
It is provided by the [dimension plugin](/reference/plugins/dimension/).

To be able to use this plugin, you need to give your dimension an id:

## Signature

```js
macro('rmd', { 
  String id
})
```

## Example

  macro('ld', {
    from: new Point(10, 0),
    to: new Point(40, 0),
    d: 5,
    id: 'da',
  })

  macro('ld', {
    from: new Point(10, 20),
    to: new Point(80, 20),
    d: 5,
    id: 'db',
  })

  return part
}
```
