<p>How do you get 14 sides instead of 12 with a 30 degree angle?</p>
<p>I used a formual found here: <a href="http://mathworld.wolfram.com/RegularPolygon.html" rel="nofollow" target="_blank">http://mathworld.wolfram.com/RegularPolygon.html</a></p>
<blockquote><p>R = (a / 2) * csc(Pi / n) where 'a' = side length and 'n' = 360 / angle</p>

<p>There are three approaches that make sense to me, which one is best for you depends on what parts of this you want to be variable.</p>
<ol>
<li>Just use the polygon component. You'll have to convert your desired angle into a segment count.</li>
<li>You can either start with a circle and divide it either into a integer number of segments (the corners of your polygon, but only if your corner angle divides 360 exactly), or into specific length segments for when you have a corner angle which…</li>

<li>You can either start with a circle and divide it either into a integer number of segments (the corners of your polygon, but only if your corner angle divides 360 exactly), or into specific length segments for when you have a corner angle which doesn't fit neatly into 360 degrees. I guess the latter wouldn't really be a polygon since it wouldn't be fully symmetric, but maybe that doesn't matter in this case.</li>
<li>You can set up a range (or series) of angles, then create points using polar coordinates. This way you have a lot of control over both the angle per segment and the amount of segments, but it's a bit harder to figure out exactly how many segments you need for a fully closed polygon.</li>
</ol>

<p>There's probably other ways as well, but you'll need to be more specific about what exactly you're after.</p> Do you mean a dodecagon?

<p>If that's what you want specify 12 sides for the Polygon component.</p>
