Flat milling with raised remainder
Please also note: Kurzeinführung Frontplatte.
Problem:
You want to remove 1mm from a 4mm thick front panel, with a cylinder remaining in the middle. Optically a rounding of 1mm height lies on top of a rectangular plate. How do you mill such a thing?
Solution:
Divide the rectangle around the circle into 2 halves.
Image 1: The half is highlighted in orange.
Then draw this half two times: First draw the half from an open rectangle from the drawing menu. Select the left edge and get 2 black boxes at its ends. Now hover over a black box and give it a right click M2. Now this context menu appears:
The ligne will be devided in 3 parts. Now you can move the little inner boxes by left mousekey held M1H. Now drag the inner line segment to a half circle.

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.
