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:

Image: Draw half a rectangle using the unfilled rectangle tool from the drawing menu.

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". The ligne will be divided in 4 parts having three vertices in the middle. Now you can move each of the little inner box along the line by left mousekey held M1H. Now drag the inner line segment to the right to give it a circle. Do so by using the arc icon:

Image: Look at sidebar to the right, select the arc-tool, drag the line to an arc.

Now select the structure consisting of an arc and 5 straight lines and press the [e] key to edit. The dialog opens where you tick the following boxes:br>

Now you enter the new property FPBREAKOUTDEPTH and enter value 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.
