Cad floor plans

[babell2]

Has any one done the work for CAD floor plans for the basic buses out there for conversions?  I am starting on a new conversion (November 19th) on an MCI-9 still in passenger mode, 47 seats to remove.  Does a CAD floor plan of the bus it's self exist.  This would help immensely in not putting a lav over the rear axle etc while the other changes take place.
