Joost De Cock b34a2ee2ed feat: Flat import of markdown repo
This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo

Share dimensions between pattern parts developers Shows how to share dimensions between similar pattern parts
See this example in our source code

When you have different pattern parts that look similar -- like the front and back of a garment -- you may find that there's a lot of dimensions shared between them.

The example below is from Aaron where dimensions are shared between the back and front part.

Aaron has a file called shared.js that looks like this:

export function dimensions(macro, points, sa) {
  macro('hd', {
    from: points.cfHem,
    to: points.hem,
    y: points.hem.y + sa * 2.5 + 15
  })
  // more dimensions here
}

In both front.js and back.js we use this code to add these shared dimensions:

import { dimensions } from './shared'

// ...

  if (paperless) {
    dimensions(macro, points, sa)
    // ... specific dimensions 
  }

Since our shared dimension method is a so-called named export we need to import it with the syntax you see above.
