title: ld
---

The `ld` macro adds a _linear dimension_ to your pattern.\
It is provided by the [dimension plugin](/reference/plugins/dimension/).

<Example part="point_dist">
An example of a linear dimension
</Example>

```js
macro('ld', {
  from: points.from,
  to: points.to,
  d: 0
})
```

| Property        | Default | Type                | Description |
|-----------------|---------|---------------------|-------------|
| `from`          |         | [Point](/reference/api/point) | The startpoint of the dimension |
| `to`            |         | [Point](/reference/api/point) | The endpoint of the dimension |
| `d`             | 0       | Number              | The offset at which to draw the dimension |
| `id`            | auto-assigned | String | A custom ID under wich paths and points will be created |
| `text`          | Linear distance   | Number    | The text to go on the dimension if not the from-to linear distance |
| `noStartMarker` | `false` | Boolean             | Whether to not draw a start marker |
| `noEndMarker`  | `false` | Boolean             | Whether to not draw an end marker |

<Note>

Setting a custom ID will:

- Allow removal of the dimension with [the `rmd` macro](/reference/macros/rmd)
- Prevent removal of the dimension with [the `rmad` macro](/reference/macros/rmad/)
