  <title>Yet another manifold issue</title>

  <description><![CDATA[Howdy, all, I've got a model of the <a href="http&#58;&#47;&#47;en.wikipedia.org/wiki/Apple_of_Discord" target="_blank">apple of discord</a>. However, the text etched on the apple makes the model non-manifold. Here is the interior view of one of the letters:<br />

<br />
I've been trying to fix it in MeshLab, but I'm not exactly sure how to proceed. The .stl file is attached.]]></description>

  <description><![CDATA[Hi Ushanka;<br />
<br />
The issue is that the letters are not manifold. The back surface of them that intersect with the apple are not closed. And they are rather jagged as well. <br />
<br />
In addition, the bottom of you stem is not closed either. <br />
<br />
I am becoming a big fan of Meshlab, but can't tell you how to fix it with that quite yet. <br />
<br />
Walking you through fixing this in Blender would be a Tutorial all its own. So I'll just explain the basic gist.<br />
<br />
the stem I just closed by extruding the edges to a point, and then removing the doubles.<br />
<br />
The letters, I separated from the model making them there own mesh. Moved them to a separate layer. Then looking down (Num 7 in blender) I deleted all the verts beyond the front faces of the letters. I.e. Reduced the letters to only they're 2D faces. And then extruded them along the normals. I also hollowed out your apple as it would cost $330+ USD to print as a solid object.]]></description>
