+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"
+  caption="An example of a linear dimension"
+/>
+
+```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/)
