The corners are rounded, but you want arcs!
You can try to use Anthonys toporouter (rubberband), if it works for you
you get nice arcs (You also can manually insert arcs in pcb...).
Unfortunately Anthony's work was not continued, examples disappeared
from the net. But it may be possible to use it. I am not sure if the
last pcb snapshot works with toporouter -- the one before worked, and
current development version may work too.
I am one of the persons loving rubberband routers -- seems that not
many people really do. In summer I read some of the related papers and
had a short look at Anthonys 8k lines of C code -- I guess my chances to
understand it are not really good. I have started my own coding in Ruby
-- unfortunately the topic "generating a rubber band sketch" is not
described in detail in available papers. Other topics are, like layer
assignment and net ordering. Coding rubberband routing is much fun, but
maybe I am not smart and patient enough for that stuff. Currently the
output of my code is only some kind of modern art, drawn by cairo.
