Why did you duplicate the origin planes rather than use them?
Why do you use zero length dimensions rather than coincident constraints?
In general wayyyyy too many dimensions that could be replaced with geometry constraints (primarily coincident to midpoint or symmetry constraints).
For your problem - Extrude with taper angle (but very unusual to dimension width of flat rather than flat to flat - what standard size wrench will be used).
Then use the Replace Face command and replace that one face where no draft is intended using the workplane (which should have been one of the base planes following the BORN Technique). http://home.pct.edu/~jmather/skillsusa%20university.pdf
