Step 1 -
 
Create shape in your favorite CAD program.  Here, AutoCAD 14 has been used.
 
Export the image in dxf file format in a folder where you can find it later.
 
The dxf file can be imported into another program for scaling or other modification, or directly into Torchmate software for execution.

Step 2 -
 
Import the dxf file into the Torchmate software where it is automatically converted to G-code.
 
Note that when the shape is cut, the torch path is simulated on the screen in real time.  The dotted line represents rapid traverse moves.
