General erection drawing of the C-25.

The general erection drawing is a composite of the subassembly drawings for the locomotive -- frame, boiler, cab, running gear and valve motion, suspension, etc.  The complete CAD file also contains plan and front elevations.
I use it to check the fit between related assemblies, as well as to get an overall idea of whether the engine matches the drawings and photographs I am working from.  As the subassembly drawings are completed, the general erection drawing evolves, too.
