About Line Styles
Custom line styles can be defined and used for callouts, insets, borders as well as phantom lines to conform to corporate standards.
You can set a specific physical size for thick and thin line weights.
These custom line styles and weights mean that the published illustrations comply with corporate standards.
Define line styles by setting the line pattern and length.
The defined custom line styles can be saved as defaults for use in all new illustrations.
