The only ones I know of to draw a line would be the DF objects (2
lines, not 1) and the Area Objects. Area objects have two types of
lines you can draw but you may not be able to specify the length
down to the resolution you require. Worth trying though.
Xastir can draw these for you. Oh yea, the DF objects don't allow
you to set the length either, so they're out.
Another method might be to create a small object, send it's
position, then zip it off to a new location and use the station
track as your line.
