Mark,
Have you downloaded the new Mill2003 profiler?
I downloaded it and "played" a round with it. It will cut all the entities on the screen at once and will pick up it's own start and stop points, offset inside or outside, nest, ect....
You can zoom in or out unlimited times without losing your select function. You can select the inner tool paths, then select the outer tool paths, ramp on / off, angle on / off, select were to start from,ect.....
Looks pretty neat, I don't know what your ver is or how it works.
Just thought you might want to look at 2003, if you haven't already.
