title: Mirroring
---

<p>
    Use <a href="../api/modules/makerjs.angle.html#mirror">makerjs.angle.mirror</a> to get a mirror of an angle, and
    <a href="../api/modules/makerjs.point.html#mirror">makerjs.point.mirror</a> to get a mirror of a simple point.
</p>

<p>
    You can create a mirrored copy of paths and models with the following functions.
    The mirroring can occur on the x axis, the y axis, or both.
</p>

<ul>
    <li><a href="../api/modules/makerjs.path.html#mirror">makerjs.path.mirror</a>(path: object, mirrorX: boolean, mirrorY: boolean)</li>
    <li><a href="../api/modules/makerjs.model.html#mirror">makerjs.model.mirror</a>(model: object, mirrorX: boolean, mirrorY: boolean)</li>
</ul>

<p>Each of these functions returns a new object and does not modify the original.</p>

<p>Mirror path example:</p>

{% highlight javascript %}
//render a line mirrored in the x dimension

var makerjs = require('makerjs');

var line1 = new makerjs.paths.Line([0, 0], [100, 100]);
var line2 = makerjs.path.mirror(line1, true, false);

var paths = [line1, line2];

var svg = makerjs.exporter.toSVG(paths);

document.write(svg);
{% endhighlight %}

<script>
    LiveDoc.evalLastCode();
</script>

<p>Mirror model example:</p>

{% highlight javascript %}
//render a model mirrored in the y dimension

var makerjs = require('makerjs');

var ovalArc1 = new makerjs.models.OvalArc(45, 135, 50, 10);

var model = {
    models: {
        ovalArc1: ovalArc1,
        ovalArc2: makerjs.model.mirror(ovalArc1, false, true)
    }
};

var svg = makerjs.exporter.toSVG(model);

document.write(svg);
{% endhighlight %}

<script>
    LiveDoc.evalLastCode();
</script>

<p>
    Hint: When creating symmetrical models, it may be easier to create one half, and then use mirror to generate the other half.
