Mach accepts a gcode file. Something drawn needs to be converted to gcode.
So you will need a cam progam to do that. Lazycam is provided with Mach and can do the conversion.
It takes more than just hitting a button and it's done.
I don't use / haven't used in a long time Corel ,and frankly, think you would be better off spending $30 and buying a CAD program in my personal opinion.
