I guess it's possibly something about the files we generate which
becomes a problem sooner than for other files - can photoshop can import
other large EPS files?  Problem is that it's hard to know what needs
changing without some sort of error message.

Sometimes EPS files include a preview, or bitmaps in them might have
been sized with a particular DPI value in mind, but Survex exports to it
as a pure vector format, so as John says DPI doesn't make a difference.

There's code to handle exporting to EPS at a different scale, but
currently there's no UI to set it so the scale is fixed at 1:500.  I'm
intending to add a "settings" dialog for export similar to the one you
get for printing.
