These are some changes in the way the monorepo is structured, that are aimed at making it easier to get started. There are two important changes: **Multiple workspaces** We had a yarn workspaces setup at `packages/*`. But our monorepo has grown to 92 packages which can be overwhelming for people not familiar with the package names. To remedy this, I've split it into 4 different workspaces: - `designs/*`: Holds FreeSewing designs (think patterns) - `plugins/*`: Holds FreeSewing plugins - `packages/*`: Holds other packages published on NPM - `sites/*`: Holds software that is not published as an NPM package, such as our various websites and backend API This should make it easier to find things, and to answer questions like *where do I find the code for the plugins*. **Updated reconfigure script to handle build order** One problem when bootstrapping the repo is inter-dependencies between packages. For example, building a pattern will only work once `plugin-bundle` is built. Which will only work once all plugins in the bundle or built. And that will only work when `core` is built, and so on. This can be frustrating for new users as `yarn buildall` will fail. And it gets overlooked by seasoned devs because they're likely to have every package built in their repo so this issue doesn't concern them. To remedy this, we now have a `config/build-order.mjs` file and the updated `/scripts/reconfigure.mjs` script will enforce the build order so that things *just work*.

About
This plugin adds the ability to export patterns to DXF-ASTM.
DXF (Drawing interchange format) is a file format developed by Autodesk
(of AutoCAD® fame).
The DXF-ASTM variety is a subset of the format, specifically targetted
at the garment industry.
ASTM is the American Society for Testing and Materials — a standards body — that published the format. DXF-ASTM is the successor of DXF-AAMA which was developed by the American Apparel Manufacturers Association which reveals the origins of the file format.
Usage
Instantiate your pattern, and use the plugin.
It will add the exportDxf() method to the pattern object.
This method will return the DXF-ASTM output.
import models from '@freesewing/models'
import Aaron from '@freesewing/aaron'
import exportDxfPlugin from '@freesewing/plugin-export-dxf'
const settings = {
// Make sure to set complete to false
complete: false,
measurements: models.withoutBreasts.size42
}
let dxf = new Aaron(settings).use(exportDxfPlugin).draft().exportDxf()
Configuration
This plugin takes a configuration object as a second parameter to the
pattern.use() method.
Precision
The precision property determines the length of the line segments used to approximate curves. The generated DXF-ASTM output will only contain straight lines, so curves will be approximated wiht lines segments.
The precision sets the length of those segments in mm.
In the example below, the precision is set to 25 resulting in
the use of line segments 25mm (1 inch) to approximate the curve.
let config = {
precision: 25
}
let dxf = new Aaron(settings).use(exportDxfPlugin, config)
The default precision is 1, giving you 1mm long line segments
to approximate curves.
Reasons to use this plugin
This plugin can export your pattern to DXF-ASTM so you can import it to your 3D software of choice.
Reasons to not use this plugin
Because DXF is inferior to SVG in every way
DXF (and DXF-AAMA and DXF-ASTM with it) are rooted in the world of industrial manufacturing. And it shows.
Nowadays, it's easy to think of the DXF file format as a bit of an embarassment.
But it is deliberatly kept dumb so that old industrial CNC milling machines,
plotters, laster cutters and whatnot, can handle the format.
Because this plugin does not implement all of DXF
This plugin does the minimum to allow export of FreeSewing patterns into 3D garment tools. It expexts the input pattern to only include the outlines.
That means, no seam allowance, or titles, no notches, and so on.
