the only thing you really need during a visual pattern is to have the rwy in sight.
for orientation i usually start with rwy-point/-3 [that where i want to turn final and be 1.000ft]. from that point 90° and again 3NM gives the base turn [~2.000ft]. from this one finaltrack/3 gives the entry for the visual.
now you have a magenta " 3-mile-box". depending how sleep deprived you are you could fly this with LNAV/VNAV. but its more fun to fly the plane by yourself.
