It has been mention before, but I would like to bring it up again just so the developers are reminded of this. There is a great interest in having a "cable" or "wiring" environment, even a very basic one.
I can envision a small step in the right direction, wherein you designate the face of a part as a "connector" and then, through a wire command, generate a 3D spline between the two faces (hopefully with the handles of the spline locked normal to the face of the part). From there, the user could manipulate control points to move the pseudo wire to the appropriate places, and could just use the "pipe" command to generate the bodies of the wires. This is basically what is done right now, except for the need of tediously creating a bunch of sketches and including 3D geometry of things; this would help automate this process.
Integration with AutoCAD Electrical (such as already existed between Inventor and AutoCAD E) could help automate this process, or creating a seperate ECAD drawing environment native to Fusion360.
This, combined with the already present interaction between Fusion360 and EAGLE, would put Fusion at the forefront of electromechanical CAD solutions, and allow for one software to be used by EE's and ME's for very quick collaboration and iteration on design.
