Re: help us please we really need it ASAP...............thanks

I would make the part exact for all references, then with a different
layer, and double lines, it would be easy to just snap to points to
follow the contours. also makes easy work of toolpaths, AND you get
the added benefit of going 10 thou under then on-size for rough and
finish cuts. Then, just save the layer.
