if you have a file that will open in cut 3d then you can toolpath it in cut 3d. it will produce gcode as long as there is a post proccessor for your machine. and i am 99% sure there is.
so what is the file extenxion of your file, EX .stl? .v3m ?
you have cut 3d? or just the file ? what cnc do ypu have and what software are you using?
if the file came from vectorart3d.com then james provides free software to machine it.
