You can set your view to match your work plane by View/Camera/Plan/By Workplane. There may be a better way to match the two up, but that's the one I know . Doing all your work on the World workplane and then extruding components into the z dimension would be another.
Ok! so I have the first object drawn and extruded...into the Z plan. It's sitting on edge on the workplane, (so I'll ignore that for now).
So, to draw another object, ( how do I set the next workplane, so it will end up where I want it)? [Appearing as though the two widest faces, (the first of which currently appears to be perpendicular to the workplane), are on the same real world plane]
