The replaces the NextJS site powering FreeSewing.dev with a Docusaurus

title: Slash and spread
---
When we _slash and spread_ a pattern, we cut out a triangle, and then rotate it
around the tip of the triangle.
And that's exactly what we do in code. We just need to know:
- What point we want to rotate around
- Which points we want to rotate
- By how much we want to rotate
```js
let rotate = [
'splitEdge',
'neckEdge',
'cfNeck',
'cfNeckCp1',
'neckCp2Front',
'neck',
'shoulder',
'shoulderCp1',
'armholePitchCp2',
'armholePitch',
'armholePitchCp1',
'armholeHollowCp2',
'armholeHollow',
'armholeHollowCp1',
'splitCp2',
'frontNeckCpEdge'
]
for (let p of rotate) {
points[p] = points[p].rotate(options.chestShapingMax * options.chestShaping * -1, points.split)
}
```
