Modifies the width values of existing lineweights.

The following options are displayed.
Lists the lineweights in the plot style table. You can modify existing lineweights, but you can't add or delete them. If you change a lineweight value, other plot styles that use the lineweight also change.
When you edit a lineweight value, it is rounded and displayed with a precision of four places past the decimal point. Lineweight values must be zero or a positive number. If you create a lineweight with a zero width, the line is plotted as thin as the plotter can create it. The maximum possible lineweight value is 100 millimeters (approximately four inches).
