This function assigns pre-determined sewer parameters for pipes and structures from selected 3D polylines that have been previously drawn to the screen and converts them to a Sewer (*.SEW) file. This command is very similar to the Import Sewer Network from 2D Polylines command and the Import Network from Centerline/Profile command. Sewer structures are inserted at the polyline vertices with the base elevation of the structure taken from the polyline vertex elevation. Pipes are created to replace the polyline segments and the invert elevations of the pipes also come from the polyline vertex elevations.
System Name: Indicate the system designation for the incoming sewer entities. A *.SEW file can have multiple systems (e.g. A, B, STRM1, STRM2, etc) within it.
Starting Structure Name: Indicate the designation that is to be assigned to the first structure (i.e. a junction) to be created by the routine.
Starting Pipe Name: Indicate the designation that is to be assigned to the first pipe that will be created by the routine.
Rim Elevation By: Set toggle to desired option. Fixed Elevation, Surface Model when enabled, this option allows you to click the Surface File button indicate a valid Carlson surface file (generally created through the Triangulate & Contour command) as the source for the new rim elevations, and Depth to Invert
Rim Elevation: Indicate a single desired rim elevation to be applied to
all new structure locations.
Invert Depth from Rim: Indicate the desired
depth from the rim elevation.
Structure ID: Indicate the type of structure to be used for the new sewer data or click on the Library button to access the Sewer Structure Library command to create a new structure definition or edit an existing structure definition. If this is an utility network (i.e. waterline, gas line and etc.) where there's no structure, you can choose None as the Structure ID. Therefore all the junctions would become an elbow pipe connections.
Inlet ID: Indicate the type of inlet to be used for the new sewer
data or click on the Library button to access the
Inlet
Library command to create a new inlet definition or edit an
existing inlet definition.
Symbol Name: Select the symbol to be
used.Click on the Select button to access the Symbol
Library. If this is an utility network (i.e. waterline, gas line and etc.) where there's no
structure, you can choose SPT0 for no symbols.
Symbol Size: For the size of the symbol
three options are available, Inlet Library Width, Drawing Scaler,
and Unit Symbol
Pipe Material: Indicate the type of material to be used for the new pipes or click on the Library button to access the Pipe Material and Manning's n-Library command to create a new pipe material or edit an existing pipe material definition.
Pipe Shape: Indicate the general pipe shape that is to be applied to the new pipes.
Pipe Size: Indicate the desired pipe size for the new pipes or click on the Library button to access the Pipe Size Library command to create a new pipe size or edit an existing pipe size definition.
Pipe Manning's n: Indicate the desired Manning's n-value to be applied to the new pipes.
Pavement Manning's n: Indicate the desired Manning's n-value to be applied for storm sewer network runoff considerations or click on the Library button to access the Pavement Manning's n-Library command to create a new Pavement Manning's n-value or edit an existing Pavement Manning's n-value definition.
Pavement Cross-slope: Indicate the desired pavement cross-slope for ponding width calculation purposes.
Pavement Longitudinal Slope: Indicate the desired pavement longitudinal slope for ponding width calculation purposes.
Select 3D polylines.
Select objects: Select the desired 3D polylines that are to be converted
and press Enter when complete. If several polylines are met at one
vertex, only one structure is created, and the first polyline is
the main flow line, others are the upstream branches.
The sewer network will be drawn on the screen as the routine completes and can be manually drawn later through the Draw Sewer Network > Plan View command.
