How do I convert curves to coordinates?

1

I am a beginner in electronics and I recently bought the uarm swift and too excited to try some things out. I was planning to make it write words on a paper that I give it as an input. I split it into two modules, one is finding the right (x,y) coordinates for each alphabets (each alphabet would follow the same font and have the same size for convenience).
and other is programming it with those coordianate data and accepting text as input and act accordingly. For the first part, the easy way I thought, would be, to use cura and convert the text I draw in autocad or rhino into gcode. But the problem is , seems cura is suited for printers, it asks parameters for a 3d printer. My qn is , to convert whatever i draw, into coordinates what procedure should I follow?
