Drag Bit Toolpaths

You have a couple of options to generate a toolpath for a drag engraver:

Use Carbide Create, or any other 2D CAM program, to generate contour toolpaths and pocket toolpaths with an RPM of zero (or leave your spindle turned off).
Use the Engrave toolpath in Carbide Create Pro to generate outline and fill toolpaths for drag engraving."

It is not really very relevant to MoI. ?
