James, the file size is 14,1 MB, still much detailing to do so it will surelly go up.
Aegedus, i usualy draw from plans that i find on the web, but i use AUTOCAD to draw the plans and elevations of the vehicle or building, after that i import the DWG file in sketchup and start modeling, extruding and intersecting the drawings. It's hard to draw on sketchup over the plans because it doesn't have so many tools has CAD software, so i try not to do this, the only exception is small parts that do not need much precision.
