Last one for today I hope.  I am measuring from one plane to another.  Both planes are in the Z axis.  When I measure all that is displayed is a dimension from one plane to another in the X dimension.  Nothing at all is displayed in the Z height.  Or y for that matter.  I am selecting the xyz measurement icon on the measurement bar and all I see is one dim.  Where are the other two?  Also, when I measure something and I get my results, is there a way to reset the base or originating pick and to measure again?  I do not want to have to pick measure, have it turn off, then pick it again to have it turn on and then measure again.

Thanks
