It's basically meaningless technobabble.
There are some theories that say the Universe has additional dimensions beyond the obvious three, and time is sometimes considered as the "fourth dimension" (again, in addition to the three spatial once that we're familiar with). However, beyond that, there's no real meaning that can be ascribed to any of these dimensions; we're not even sure they "really" exist (the math in certain physical theories works out nicely if they do, but the universe as a whole doesn't really care about how nicely our mathematics works).

Length IS a dimension (in space). It has no thickness.
Lines that define the parameters of a dimension.Dimension lines are thin lines terminating in arrowheads. Place dimension lines no closer than 3/8" from the object outline. Parallel dimension lines should be a minimum of 1/4" apart. You may place parallel dimension lines more than 1/4" apart so long as the spacing between dimension lines is uniform throughout the drawing. Dimension lines are generally broken in the center of the line to provide a space for the dimension figure. Dimension figures for parallel dimension lines are staggered. In some structural or architectural drawings, you may find dimension figures placed above the dimension line.

One ninth of 90 degrees is 10.
Basic dimension is the numerical value defining the theoretically exact size of a feature. Reference dimension is the numerical value enclosed in parentheses provided for information only and is not used in the fabrication of the part.
