Great, so its all done finally, leaving me unrouted lines to clean up - all Grounds! Go figure.
BTW -you may place the crystal beneath the 1284p (see the dil40 machine pin socket there are such "windows"), I did it with dil28 narrow socket as well - Unless you plan to change the crystal too often it saves a lot of space. As the heights is concerned it fits nice..
IC1 is also a good candidate to be put underneath the 1284p..Btw, is the package of the IC1 really so wide??
I suppose I could have it do the routing with no hatching, strip out the grounds, clean up by hand, then let it try & put the hatching in again. Likely just leave me with unconnected grounds again.
I think part of the reason for the ugliness is the shield footprint.
