HI Mike,
First, I usually do a pretty decent job on finishing even my profiles. But, yours is exceptionally nice. 
Second, I have worked in coreldraw for quite a while now, does it actually cross over to CAD? (I do know it is vector based, not raster)
Thanks!
Bill
Bill;
Corel files are vector based not raster based, so Corel will allow you to save to either .dxf or .dwg format, and that is the format native to Autocad and its derivatives.
The results can still be a little "jervous and nerky". So, finishing the conversion into something useable and editable in Autocad sometimes requires some third party LISP programs or other "creative approaches".
For example, some of the curves created in Corel would not always work some CNC based machines. So, for something done in Corel, we had to convert it to a .dxf file. That would take everything back to simple curves, arcs, lines, polylines, etc. Then the CNC could handle the file and make the cut.
Walt Umland's laser cutter seems to handle everything, including splines. Things develop with time.
