<h2>Instructions:</h2>
Create a new file in your favorite text editor. To get started enter the following text:
<br>
<pre>function main() {
var cube = CSG.roundedCube({radius: 10, roundradius: 2, resolution: 16});
var sphere = CSG.sphere({radius: 10, resolution: 16}).translate([5, 5, 5]);
return cube.union(sphere);
}
</pre>
Save this to a file on your desktop with .jscad extension. Then drag &amp; drop the file from your desktop
to the box above (marked with 'drop your .jscad file here).<br><br>
The 3d model should now appear. You can continue to make changes to your .jscad file. Just press Reload
to parse the changes, you do not need to drag &amp; drop the file again.
<br><br>
When finished press Generate STL to generate the STL file. Then click Save STL and save it to
a file with .stl extension.
<br><br>
