Please also note: Crash course frontpanel.
Problem:
You want to remove 1mm from a 4mm thick front panel, with a cylinder remaining in the middle. Optically a cylinder of 1mm height lies on top of a rectangular plate. How do you mill such a thing?
Solution:
Divide the rectangle around the circle in 2 halves. Leave out a semi-circle from the middle in each of the two halves. Mill these two forms flat a bit so that the center cylinder remains at the end.
Remember that a flat milling only works within the boundaries of a frontpanel contour. The edge can be very narrow but at least a bit more than 1 nanometer inside of it. That is how you start:
Highlight it and get black boxes at its ends. Now give it a right click M2 on the left middle box. Select from the context menu: "Insert two vertices"

Image: Look at sidebar to the right, select the arc-tool, drag the line to an arc.
Image: The half is highlighted in orange. If you calculate the milling outline for production, it becomes green.
Now select the structure consisting of an arc and 5 straight lines and press the [e] key to edit.

Now you enter the new property FPBREAKOUTDEPTH and 1.000.000 for this object (one million). TARGET works internally in nanometers (nm). One nanometer is one millionth of a millimeter. In other words: 1.000.000nm = 1mm. The lines now represent the boundary of a flat milling that is one millimeter deep. Copy and paste it for the second half and have it produced.
