Interesting idea. We will have it hooked into Mach4, so you can directly load the file into M4. You w il also be able to enter values into the grid for the polyline, so you can do a CopyCat like function- move the M4 axis around, just click a button and the X,Y values will load into the grid.
Lots more coming, just got to work in my retired time frames, and when I can get some time from Brian for the harder parts.
