# Convert GeoJSON to ASCII STL
### Installation
```sh
npm install geojson2stl
```
### In the terminal
```sh
geojson2stl example.geojson
```
#### Flags
-o
--output
Sets the output file path and file name
_Default_: ./output.stl
-e
--extrude
Sets the millimeters to extrude the shape
_Default_: 1
-s
--size
Set the maximum dimension (in x or y dimensions) of the output shape in millimeters
_Default_:200
example
```
geojson2stl -s 150 -e 10 -o ./example.stl example.geojson
```
returns a 150mm maximum dimension, 10mm extrude file named example.stl
### in Node
```js
const geojson2stl = require('geojson2stl');
const fs = require('fs');
fs.readFile('./myFeatures.geojson', 'utf-8', (err,data) => {
let options = {};
options.size = 150; //150mm maximum width or height
options.extrude = 5; //extrude 5mm in z axis
let stl = geojson2stl(data, options);
...
...
});
```
## Reference
geojson2stl(geojson[, options]]) <>
Takes a required parameter of geojson and returns ASCII STL text of the input geojson. Options is an opject with the following optional attributes:
* ``` output``` - filename to give name attribute in STL file _default_: 'output.stl'
* ``` extrude``` - a number indicating millimeters to extrude the shape _default_: 1
* ``` size``` - a number indicating the maximum dimension of the output shape _default_: 200
## Caveats
expects geojson as WGS84 (as per the [specification](https://tools.ietf.org/html/rfc7946)) and projects all coordinates to mercator.
