204.2 Types of Line Styles
ODOT CADD Standards contain two (2) types of custom line style definitions:
January 18, 2013
1. “Cosmetic” line styles
Cosmetic line styles are used to represent the location of an item, but not the actual size or
spacing of the item. A fence line, shown below, is an example of a cosmetic custom line style.
• The location of the symbols along the custom line style does not represent the actual
location of fence posts, and are intended only to designate the line as a fence line.
• Cosmetic line styles are typically placed in the design file at a scale of one (1) and then
displayed using the Global Line Style Scale or Annotation Scale factors in the design file at
a scale corresponding to the intended plotting scale of the final plans.
2. “Physical” line styles
Physical line styles are used to represent the location of an item, and the linear spacing of the
components of the item. A pavement marking lane line, shown below, which consists of
alternating 10’ dashes and 30’ gaps, is an example of a physical custom line style.
• Physical line styles are always placed in the design file at a scale of 1, regardless of the
plotting scale.
• Physical line styles are designated as such that the Global Line Style Scale and Annotation
Scale factors when applied are ignored.
Cosmetic and Physical line styles for plan graphics are specified in the CADD Information Table,
Appendix A and displayed in Appendix D.
