Mark,
        I cannot really help you with your enquiry but your comments were
curious. Which Anasoft package is your engineer using? We also use Anasoft
here and we seem to have no problems with curved traces, our engineers use
them everywhere, much to my chagrin since Protel curved traces can be a
little difficult to control at times.
        Sorry that I am little late responding our local ISP had troubles
and we have been off external email for a couple of days.
