Contour 3D internal cam error

[hackish]

I've attached the file in question. I'm not sure why it is giving the error, but I suspect it is something to track down and write logic to catch it and give the user directions on what is wrong.

There is no pocket to machine in the selection. I'm not even sure how this was created. From what i can tell your pocket selection was vertical edge in the Z-axis. This is not a valid pocket selection in the current tool orientation. 

Also the error is on a 2D adaptive, not a 3D contour toolpath.

Oops, I think you're right, since I had tried a number of strategies. In any event, I think an internal CAM error indicates a bug. Probably the processor should detect a situation like this and give an error message that describes the issue.
