Line Weights

The solid lines representing walls, cabinets
and doors are rescaled to be eight times
thicker than in the original view.
Similarly, the dashed lines representing the
door jambs are rescaled so that the dashes
and the spaces between them are eight times
larger than in the original view.

with Use Layout Line Scaling enabled
Because the view in this example is scaled
eight times larger in this case, the dashes and
line weights look relatively small and fine
when Use Layout Line Scaling is enabled.
Were the view rescaled to be smaller instead,
the line weights would look relatively large
and thick.
with Use Layout Line Scaling disabled
If Use Layout Line Scaling is enabled, line Printers and Line Weight
weights are no longer scaled and the dashed
lines display at the same size as in the Line weight and print scaling are subject to
original view. the limitations of the printer being used. For
example, you will not be able to see the
difference between a line that is 1/150th of
an inch wide and one that is 1/300th of an
inch wide when they are printed using a
printer that prints 150 dots per inch (DPI).

That is, a CAD line with a line weight of 1
will look the same as a CAD line with a line
weight of 4 when the Line Weight Scale is
set at 1 = 1/600th of an inch and you print to
a printer capable of 150 DPI.
