Support "From Stock" REST machining on multi-pass CAM operations

[Anonymous]

When creating a multi-pass operation, each pass traces exactly the same toolpath, just at different heights. It would be nice if the toolpaths independently computed the Rest-style information. Consider this toolpath:

If we create this as a multi-pass operation, you will get the exact same path, only higher, with lots of air cutting.

I can create the higher toolpath as a separate operation, with "leave stock" set to some value (.125" in this case), REST set to "from stock" and I will get this toolpath:

In an ideal world, a multi-pass operation with REST set to "from stock" would go ahead and generate this upper path for me.

(and because there is almost CAM api exposed, I can't create a script to do this.)

Model is attached.
