Layout of wires and shafts, plumbing via lines

[chrissilva]

Feature request: layout and mass properties of wires, shafts, plumbing between components.

Often, the mass properties of power transmission systems such as wires, shafts, and fuel plumbing is well estimated by applying a mass/length and making simple connections following the topology of the system. I'll admit that the details of implementation will probably be tricky, and if not careful solving the path between components will be unstable and perhaps difficult as we move things around. But it is worth thinking about how to implement these, especially for electrical power distribution. I do not think that fitting wires inside a wing or something else is something we want to tackle at this point, as simple topological connection will help immensely with the important mass properties questions.
