The CAD software I use, Pro-Engineer, has an assembly mode where you can create simplified representations of the assembly you are working on. One simplified rep I have defined is the 'Build' state where I blank parts that are finished and today I went into it and checked off 'arm-upper-bearing.prt'. The current build status is:
The fixture was simple, a machined boss that would locate in a bearing bore and a threaded hole to clamp the part down. I also had to machine a step to keep the part from spinning due to machining torque.
