January 18, 2013 203 Colors 203.1 General Standard colors are specified to ensure consistency and to enable users to easily identify plan elements in shared files. Each element in a MicroStation design file is assigned a color number. MicroStation reads a color table to determine the correct color to display for the specified number. Standard color numbers for plan graphics are specified in the CADD Information Table, Appendix A. The ODOT standard color table, ODOT_color.ctb, can be obtained from the ODOT CADD Standards website. The MicroStation configuration variable MS_DEFCTBL is used to specify the ODOT color table. The color values may vary or appear different on screen due to the graphics cards, monitors display capability, etc. 204 Line Styles 204.1 General Line styles are used to differentiate curvilinear elements in the design file and on the plotted sheet. There are eight default line styles available in MicroStation using the values zero (0) through seven (7). Additionally, ODOT has developed a set of Custom Line Styles to be used for drawing various plan view graphic items requiring custom symbology. Custom Line Styles are created as Cosmetic or Physical line types. For detailed information see Section 204.2 Types of Line Styles. The ODOT standard line style resource file, ODOT_Linestyles.rsc, can be obtained from the ODOT CADD Standards website. The MicroStation configuration variable MS_SYMBRSC is used to specify the custom line style resource file. Users shall not create their own custom line styles for use on ODOT plan sheets. Standard line codes and custom line styles for plan graphics are specified in the CADD Information Table, Appendix A and displayed in Appendix D. 18 ODOT CADD Engineering Standards
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. ODOT CADD Engineering Standards 19
