Motors, solenoids, fuses, terminal blocks, gages, switches, curcuit breakers, etc. Right now I've been creating them with a part file and bringing them into an assembly drawing and connecting the features with a sweep. A little cumbersome, but easy to manipulate. Looks cool, too in isometric view.
Like I implied before, Solidworks is the only software at my disposal at this facility.
Cadkey is one of my favorites. Did a lot of tubes for turbine engines with it and fixture design, but it and Autocad won't do me any good here.
Visio I use for outlining my manufacturing processes on more complicated assemblies, some of the management can interpret this easier, but the line jumping can be a pain if you're in a hurry.
