Thanks Alan. Yes, modelled using Inventor and then rendered in Inventor. I think I did it in Inventor 2008 or 2009. Cheers Steve
The ribbon cables are done using the ribbon cable tool in Inventor and the wires\cables are imported from the AutoCAD Electrical schematic and automatically routed between the components so none of the cables were actually modelled manually. Cheers Steve
