title: "@freesewing/plugin-measurements"
|
||
|
|
---
|

|
|
|
||
|
|
The **@freesewing/plugin-measurements** plugin attaches
|
||
|
|
to [the preDraft lifecycle hook](/reference/api/hooks/predraft) to
|
||
|
|
provide a number of extra measurements to your pattern insofar as
|
||
|
|
they can be deduced from the measurements that are provided.
|
||
|
|
|
||
|
|
It will add the following measurements:
|
||
|
|
|
||
|
|
- `seatFront` (if both `seat` and `seatBack` are provided)
|
||
|
|
- `seatBackArc` (if both `seat` and `seatBack` are provided)
|
||
|
|
- `seatFrontArc` (if both `seat` and `seatBack` are provided)
|
||
|
|
- `waistFront` (if both `waist` and `waistBack` are provided)
|
||
|
|
- `waistBackArc` (if both `waist` and `waistBack` are provided)
|
||
|
|
- `waistFrontArc` (if both `waist` and `waistBack` are provided)
|
||
|
|
- `crossSeamBack` (if both `crossSeam` and `crossSeamFront` are available)
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm install @freesewing/plugin-measurements
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Like all [build-time plugins](/guides/plugins/types-of-plugins#build-time-plugins), you
|
||
|
|
load them by passing them to the [freesewing.Design](/reference/api/design) super-constructor:
|
||
|
|
|
||
|
|
```js
|
||
|
|
import freesewing from "@freesewing/core";
|
||
|
|
import measurements from "@freesewing/plugin-measurements";
|
||
|
|
import config from "../config";
|
||
|
|
|
||
|
|
const Pattern = new freesewing.Design(config, measurements);
|
||
|
|
```
|
||
