What I have done in the past when needing accurate plasma cut parts is to first print out the drawing on paper.

Stick the drawing to 1/4 or 3/16 ply, then carefully cut the ply out using my small band saw or other wood working tools of choice.

The ply can then be used as a template to run the plasma torch around.

As long as you hold the torch at the right stand off the ply does not get burn and can be used several times.

You need to factor in the radius of the torch nozzle when doing the drawing if sizes are critical.

I made a couple of drive sprockets for mini excavator rubber tracks like this and they work surprisingly well.
