		<description><![CDATA[Many beginning surfacers struggle with 3-way corners. By simply establishing a &#8220;dominant&#8221; corner, you can avoid the pitfalls associated with three-sided tertiary surfaces. Don&#8217;t worry, it&#8217;s not as hard as it sounds!]]></description>

Several people have asked me how to model the back of an iPad lately, so here I&#8217;m going to show the basic idea in a couple of very quick vids. I hope this helps!

		<description><![CDATA[So now that you know what continuity is, you&#8217;ll want to know how to analyze the continuity of your curves and surfaces in your CAD system. Each system has its own specialized tools, but there are a few common ones that are available in basically every CAD package: porcupine (aka &#8220;Curvature Combs&#8221;), Zebra, and color [...]]]></description>

Here we&#8217;ll look at the basic principles of &#8220;continuity&#8221;, and use these principles as the basis for a longer-term study on class a surfacing continuity. [...]]]></description>
