This command converts Esri sewer network shapefiles into
Carlson sewer network file (.sew) . In order to create a
Carlson sewer network file(.sew), a manholes SHP and a pipes SHP
are required. The Manholes SHP contains manhole data, and the
SHP type has to be point/pointZ/pointM. The Pipes SHP contains pipe
data, and the SHP type has to be polyline/polylineZ/polylineM.
There is also a setting to convert the ESRI SHP lat/lon coordinates
to grid coordinates which requires the grid projection to be
already defined in the Drawing Setup command.
There are Manholes Setup and Pipe Setup dialogs that match
the SHP attributes to the .sew fields.
Manholes Setup
This command uses Structure name as a key identifier and this field
is required.
Pipes Setup
This command uses input manhole and output manhole as key
identifiers to identify a pipe, and it uses these manholes to
create relationship between manholes and pipe. The rest of fields
matching are optional.
