Hi Dick,
I have checked : the ending point of an arc has the same coordinates
than the starting point of next arc, using the tool you have
developped. (5.6, 3.65 and 5.6,3.65 6.8,2.45 and 6.8,2.45).
In addition, I put in the file section other strange exports to
freerouting, with the right straight edge not correctly reproduced in
freerouting. Also boards that are impossible to export.
Please note that these problems are caused by my design, and fixing
them is not very important since I have been able to bypass with a
more simple edge design. I put it in the file section if they are
useful for you.
