The Mach3 software won't do drawings, it's the controller software for the machine and reads G code that's been done by another program.

I did the two 'nearly' matched sets last night in Vectrics, VCarve pro.

I just used a font and made one female and one male but in real life the male one has slight radii in the corners equal to the tool radius.
To work as a set of stamping dies the female one will need the same radii so it presses and not cuts.

I could do the programming if needed.
