<strong>OpenSCAD</strong> is especially geared towards mechanical, rather than artistic, aspects of 3D computer-aided design.
|
||||
Thus <strong>OpenSCAD</strong> can be useful when one wants to create a model that one wants to 3D-print.

<h2>Units</h2>

All dimensions in <strong>OpenSCAD</strong> are measured in (the somewhat confusingly named) "unit".

The <em>convention</em> used by a lot of people doing 3D-printing is:

1 unit = 1 millimeter

But <strong>OpenSCAD</strong> is in a sense unit-less.

</p>
|

<p>
|

And it is a good idea to explicitly size your model when preparing it for 3D-printing.
