<p>[QUOTE=&quot;brassnautilus, post: 2288410, member: 74300&quot;]CAD uses absolute coordinates. For organic shapes like these you&#039;d want some kind of mudbox that describes surfaces in derivatives, Zbrush for example. </p><p><br /></p><p>Instead of engraving (EDM), probably would be easier producing mirrors of the dies, with 3D print, in UV resin. This way the &quot;masters&quot; can be manually altered to rid all the tool marks, and it&#039;d be easy to obtain fairly high resolution with 3D printers that have small build spaces. Cast finished die mirrors into wax then loss-wax cast the dies in metal. </p><p><br /></p><p>For hardcore DIY we have tools ancient engravers couldn&#039;t even dream of like microscopes and micro chisels.</p><p><img src="http://i67.tinypic.com/ff3jg4.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
