The platform design template script is comprised of two DGN files which are in the Station Designer dataset extension in the path "C:\ProgramData\Bentley\OpenBuildings CONNECT Edition\Configuration\Datasets\DatasetExtensions\Station_Designer\Seed\".
The first file contains the alignments and is referenced by the second file. This second file contains a script which places guiding geometry for platform design. It places geometry for the platform edge, the copers, and guiding lines for slopes, a polygon circumscribing the area in which the platform surfaces meet when they stay within the minimum and maximum slopes, and a line string where the surfaces with "ideal" slope would meet. The script file contains comments in the list of Transactions that provide additional information about the purpose of the respective subsequent sections of transactions.
