Where is a hydraulic seed file and how is it used?
The hydraulic seed file is a DGN library which contains all the hydraulic design information you need to start a new drainage design. For practical purposes, it will usually be the same DGNLIB file which contains your drainage and utility feature definitions. The hydraulics seed is in fact, a fully functional drainage project that is copied to a new DGN file whenever a SUE command or StormCAD command is first used in in a new DGN file.
When you see the message box below notifying you that a utility project is being created, it is this hydraulic seed project which is being copied to the active DGN
The hydraulic seed which is used is defined by configuration variables:
SUDA_SEED_FILE = filepath and nameSUDA_SEED_MODEL = model in above file which contains the hydraulic seed project
