I wasn't quite sure which of the fora to use to ask this, so I thought that I would stick with the general one. Anyway, a little sub-project that is going over on Anargo is the "Venturer" project, wherein we intend to take a small (ish) and ancient vessel of the Imperium and then produce RPG statistics for the ship, the sub-vessels and equipment, the crew (old and new), 3d models (Sketchup and rendered), etc....
More importantly and of greater relevance to my question is that we also intend to provide (eventually) complete floor plans for the 1.2 km-long vessel.
Thus, for those who have engaged in this type of activity before, what software did you use?
Thanks in advance.
