Chuck, I tried your 2nd code below on my system and it seems OK to me... So just to make sure I graphed the all lines together (1 redundantly!) line1 = Line[{{0, 0, 0}, {4, 4, 0}}]; line2 = Line[{{0, 0, 0}, {0, 0, 2}}]; line3 = Line[{{0, 0, 0}, {4, 4, 0}}]; line4 = Line[{{1, 1, 0}, {1, 1, 2}}]; Show[Graphics3D[{line1, line2, line3, line4}], PlotRange -> {{-5, 5}, {-5, 5}, {0, 2}}, Axes -> True, AxesLabel -> {x, y, z}] "6.0 for Mac OS X x86 (32-bit) (June 19, 2007)" With above code do you still see a problem on your V6 on your machine?
