As soon as you select Use Outline = not good at all

I think it is working as designed. Use outline means the inside will be ignored. Uncheck that box and the pattern looks correct.

I'm afraid there's a mistake here. Using this option involves machining the entire surface of the slot, not excluding holes and deeper areas. And in this case the option completely destroys the ledge, i.e. the borders of the pocket

[GeneFC]

I guess I am missing something.

Why use that option if it is not what you want?

are we talking about the same thing? about the Pocket operation in the FC program? if yes, then on the receiver of this part, where the milling should process the selected planes - in the first screenshot in green-marsh color, then the choice of operations is not very wide. Namely, Pocket.

This option is chosen so that the program does not bypass the holes, because bypassing the holes is simply not necessary, requiring time and lines of code, and then additional grinding.

Or I am missing something.

I did not create this code, so I am not certain what is intended. However, it seems to work according to the description in the wiki.

Evening.
Per OP, the `Use Outline` feature would benefit from an improvement. It would be beneficial to add the option and/or ability to differentiate holes that are pockets (which can safely be cleared using this feature) from holes that are positive protrusions above the selected face (regions to be avoided by cutter when this option is enabled). I think that the MillFace operation has this type of differentiation available related to avoiding raised areas.

Perhaps a feature request is the solution for such an improvement here.

Thanks for identifying this issue and reporting it.

Have a great week.

No, you are not missing anything - this works exactly as designed and does exactly what it is being asked to do, namely use the outline of the selected shape and create a pocket on that.
