I've posted the DAT file for my Imperial Shuttle and some POV-Ray renderings
of it over on Brickshelf. Check it on on my Brickshelf account: http://brickshelf.com/gallery/hobartrus
The DAT file uses a "mirror method" for the wings, so it's a bit quirky...
all the pieces are standard though, it should open in MLCad without a hitch
(dunno about other editors/viewers.) Please check it out and LMKWYT.
