Started out with this part here. Kinda went out of control from there... :) For the Cell-image, the hierarchy got quite extensive and i used groups with very large numbers of children, mainly because i wanted to be able to change stuff later on with ease. It was only when i completed all the models that i connected parts like the rails for the walkway, walls etc, and managed to narrow down the objects. The pipes are both regular cylinders and splines inside sweep nurbs. The B-spline usually give a really smooth curvature so its great for wires.
