Organisation of LDraw Files
As this is a fairly complex model, the method is to break it up into smaller modules or sub-assemblies which are then fitted together. This is especially necessary as there are many parts which are joined at various angles. It is much easier to turn the parts which are joined together as a whole sub-assembly rather than turning the parts individually.

The LDraw files are organised into the following sub-assemblies:
