Thanks for your replies. One problem of the dxf output how the cubic
splines should be handled. The current solution is not very good, so if
you have a good idea, it would be great if the cubic splines will not
be converted to a set of lines but to the dxf splines that are in the
dxf format since version 13 o 14 I think.
By the way AutoTrace works readiliy also under MacOS. I never tried it
myself as I do not have a Mac but I was told by others.
Greetings
