<h2>Instructions:</h2>
|
||
|
|
Create a new file in your favorite text editor. To get started enter the following text:
|
||
|
|
<br>
|
||
|
|
<pre>
|
||
|
|
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 & 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 & drop the file again.
|
||
|
|
<br><br>
|
||
|
|
When finished press Get STL to generate the STL file. Copy & paste the STL text to a file with
|
||
|
|
.stl extension.
|
||
|
|
