Import DXF files directly into Mach 3???

How the heck does one Import a simple scribe outline line for a wing into Mach 3 directly. I milled a mold for a DLG glider which is fine but now want to make a tool change and V-tool scribe the trailing edge of the wing. I'm running Vectric Cut 3D which will not see the line because it's not 3D. I looked in the Mach 3 manual and it says to look in the file menu for direct DXF import but I do not see it. It's a simple poly line so it should work. Any help out there???????????????

The .dxf importer is long gone. You need to use LazyCAM, which replaced it, or a 2D CAM program.
