I've downloaded the Gmax program and installed it, it shows 4 grids for plotting points and different views, plus a bunch of strange buttons, however I have not yet tried to make anything or attempt to do so, I'll see once I get done reading the tutorials, maybe we could try to make that boat/airport that was on another thread, however I doubt it could be moving, but a stationary object would be pretty fine I think... I too had those Independence Day ships in FS2000 that Gergely brought up. Oh, and I have made an airport in AFCAD, a helicopter one w/ 2 rw's, one for large & another for GA planes, plus a bunch of helipads.
Cheers and I'll see if I can figure out how this thing works...
