January 18, 2013 The following dimension styles have been defined in ODOT_Styles.dgnlib: Dimension Style Font *Text Size Description Dec-0, Slanted 31 0.14 Decimal Feet, No decimal places Dec-0, Straight 30 0.14 Decimal Feet, No decimal places Dec-1, Slanted 31 0.14 Decimal Feet, 1 decimal place Dec-1, Straight 30 0.14 Decimal Feet, 1 decimal place Dec-2, Slanted 31 0.14 Decimal Feet, 2 decimal places Dec-2, Straight 30 0.14 Decimal Feet, 2 decimal places Dec-Multiline, Slanted 31 0.14 Decimal Feet, 0.01 accuracy Dec-Multiline, Straight 30 0.14 Decimal Feet, 0.01 accuracy Fract-Multiline, Slanted 31 0.14 Fractions, 1/16” accuracy Fract, Slanted 31 0.14 Fractions, 1/16” accuracy Masked Fract, Slanted 31 0.14 Fractions, 1/16” accuracy Masked Fract-Multiline, Slanted 31 0.14 Fractions, 1/16” accuracy *Text size units are “inches”. Line Terminators shall be a filled arrow created with a width to height ratio of 2.5:1. The terminator width shall equal the text height. Leader Lines may be broken when crossing dimension lines. In order to keep broken lines to a minimum, it is recommended that the user relocate the dimension callout or reposition the dimension. Leader lines and terminators shall be a weight of zero (0) and shall be placed on the same level as required for text notes and callouts. Similar to Text Styles, the text size for Dimension Styles can be set by use of the Model Annotation Scale parameter. See section 207.4 Text Styles for more information. The Multiline dimension styles have been configured to place dimension text above and below the dimension line as shown at left in the example below. These Dimension styles have been provided to allow the user to edit the dimension text to contain a label as part of the dimension element. This is advantageous in the case where the dimension is moved or modified since the text is part of the dimension and not a separate text string that must be moved manually. The MicroStation Edit Text command is used to edit the dimension text. An example of the edited text is shown at right below. Bridge plans shall use the “Fract, Slanted”, “Fract-Multiline, Slanted” or “Masked Fract, Slanted”, “Masked Fract-Multiline, Slanted” dimension styles. All Bridge dimensions shall be placed associated. Dimensions shall not have their status dropped. 48 ODOT CADD Engineering Standards
208 Seed Files 208.1 General January 18, 2013 MicroStation uses a “seed file” to create all design files. A seed file is a template in which standard parameters are set. Seed files do not typically contain elements, but like other design files they do contain settings like working units and view configurations. Using a standard, customized seed file helps maintain uniformity and keeps the user from having to adjust design file settings each time a file is created. The following two-dimensional (2D) and three dimensional (3D) seed files are available on the ODOT CADD Standards website: Dimension Seed File Name 2D ODOTSeed2d.dgn 3D ODOTSeed3d.dgn The MicroStation configuration variable MS_DESIGNSEED is used to define the default seed file. 208.2 Models ODOT’s seed files each contain two models as listed in the table below. Model Name Type Design Design Model Sheet Sheet Model For more information on the use of models, see section 303 References. ODOT CADD Engineering Standards 49
