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.
