January 18, 2013 207 Fonts 207.1 General ODOT has defined several standard fonts for use on all plans. It is important to use these fonts so that the final plotted version matches the electronic version of the file. Only the fonts provided by ODOT (30, 31, 57, and 70) are acceptable for use on ODOT plans. True Type fonts shall not be used on ODOT Construction plans. The ODOT standard font resource file, ODOT_Fonts.rsc, can be obtained from the ODOT CADD Standards website. The MicroStation configuration variable MS_FONTPATH is used to specify the font library. The following fonts are available in the ODOT standard font resource file, ODOT_Fonts.rsc: Font 30 - Straight, proportional characters with uppercase, lowercase, and fractions. This font is for general plan use and has the modified keystrokes set. Font 31 - Slanted, proportional characters with uppercase, lowercase, and fractions. This font is for general plan use and has the modified keystrokes set. Font 57 – Straight, proportional characters with the Greek alphabet in upper and lowercase. Font 70 - Block filled. This font is used on plan sheets when a bold title is necessary. Modified keystrokes are used to generate certain symbols and special characters for Font 30 and Font 31 as shown in Appendix B. Font 57 and Font 70 are also shown for reference. All text placed on Bridge sheets, excluding text contained in standard border cells, shall use Font 31. All text placed on Geotechnical Exploration sheets, excluding text contained in standard border cells, shall use Font 30 or Font 31. For purposes of this manual, the term “Geotechnical Exploration sheets” shall apply to all sheets generated per the Specifications for Subsurface Investigations (SSI) or the Specifications for Geotechnical Explorations (SGE). 42 ODOT CADD Engineering Standards
207.2 Text Size January 18, 2013 Standard text sizes have been defined to ensure uniform legibility of all plan sheets. Standard text size refers to the size of the text on the finished plot, not the text size in the design file. The correct design file text size is dependent upon the intended plot scale. ODOT standard text sizes for the finished plot scale are shown in the following table: Text Type Plotted Text Size Normal 0.14” Subtitle 0.17” Title 0.20” Main Title 0.25” To calculate text size used in a MicroStation design file for various scaled plan sheets use this method: (Text Size) x (Plotting Scale) = Design File Text Size Example: 0.14 inch x 20 feet/inch = 2.8 feet Text sizes smaller than the Normal text size are not acceptable. For all Roadway plan sheets and Geotechnical Exploration sheets, the preferred method to set the text size is by use of the Model Annotation Scale parameter. See section 207.4 Text Styles for more information. Text placed in the sheet model for bridge detail sheets should normally be placed at a scale of 1. For more information on the use of design models and sheet models, see section 303 References. 207.3 Text Line Spacing In general, Text Line Spacing should be one-half (0.50”) the text height. The spacing between lines on summary, sub-summary, general note sheets and charts is generally equal to the minimum text size. Note: If needed it is permissible to use Text Line Spacing equal to the minimum text size. Text Line Spacing distances is now relative to the Text Height. In the previous versions of MicroStation these distances were an absolute value in master units. If the text height changed dramatically, the spacing could become inappropriate. Now, if the text height changes the spacing adjusts relative to the change in the text height. The Text Line Spacing is now a factor of the Text Height. For example with the scale factor set at 0.50” (one-half) the Line Spacing for ODOT’s Text Styles would be as follows: Normal Text Size 0.14” x Line Spacing 0.50” = a Line Spacing of 0.07” Sub-Title Text Size 0.17” x Line Spacing 0.50” = a Line Spacing of 0.085” Title Text Size 0.20” x Line Spacing 0.50” = a Line Spacing of 0.10” Main Title Text Size 0.25” x Line Spacing 0.50” = a Line Spacing of 0.125” ODOT CADD Engineering Standards 43
