Thanks for spreading the word Treebore! The ship plans would probably be easier in Dungeonographer (which includes some art/icons for futuristic items) but that also has a free version. Hexographer should be good for sector maps and planetary (icosohedral) maps.
Yeah, I really hope I did make it easier to add all the symbols used in Traveller. If anyone sees a common symbol or feature it is missing let me know.
I plan to add a random generator to it... based on the original rules for that sort of thing. Have there been updates/options added to those rules?
Thanks!
