I'm new to solidworks and trying to move a line on the z axis.  I can only seem to move it on the x & y axis.  See attached image. The properties only allow me to change x & y values. 

In my drawing this line is actually a flat bar.  When in the view where I see this I saw you can turn "direction 2" on and off but i'm limited to the original line's position.

I really want to just move this line 'into' the model further but all I'm able to do is move it up/down and left/right (in relation to the 'right' plane).

Thanks for your help!
