The following prompts are displayed.

The current lineweight value is displayed. If the value is not BYLAYER, BYBLOCK or
DEFAULT, the value is displayed in millimeters or inches.

Default Lineweight

Sets the current default lineweight. Lineweight values consist of fixed settings,
including BYLAYER, BYBLOCK, and DEFAULT. Values are calculated in either inches or
millimeters; millimeters are the default. If you enter a valid lineweight value, the
current default lineweight is set to the new value. If you enter any other value,
the default is set to the nearest valid value.

To plot an object with a lineweight that is not found in the list of fixed lineweight
values, you can use plot styles to control plotted lineweights. The DEFAULT value
is set by the LWDEFAULT system variable and has an initial value of 0.01 inches or
0.25 mm. The lineweight value of 0 plots at the thinnest lineweight available on the
specified plotting device and is displayed at a value of one pixel in model space.

?—List Lineweights

Displays a list of valid lineweight values in the current lineweight units.
