Milling board outline with rounded corners

[deHarro]

Hi John,

I tried to give rounded corners to my last design and used "miter" in Eagle to form the rounded corners. The design looks exactly as expected in Eagle:

The board is double sided, the bottom layer is a GND plane with two 5 V wires.

Sadly, the milling doesn't perform as expected:

Look at those "ears" the milling process resulted in. From the design I would have expected, that the rounding starts and ends in line with the adjacent straigth lines.

Is this a problem of pcb-gcode or does Eagle something strange? Thanks!

[edit] It seems, Eagle is including the rectangular corners in the "Dimension" layer into its calculations for the route... Have I to miter the dimension outline as well? Thanks! [\edit]
