CSETPAR

This command is used to set the value of any property you may have forgotten to configure in the parts list.

For example, to create the parts list, you must set the value of the Manning Coefficient for all pipes.

Otherwise, the launch pipes in the design, they will not have the correct coefficient and the spreadsheet will show many errors because the flow rate depends on the Manning Coefficient. The flow and the water level depend on the speed. The column RULES will show many errors, which will accrue to all sections of the downstream portions error appears.

For the case of networks previously released, you can edit these values ??manually using the Civil 3D command PipeProperties.

But if you need to edit all, can be quite time consuming to do this manually.

To do this automatically, you first need to know the name of the property. Use the command CLIST for a list of the properties of the pipe or structure:

Command: clist
Select an object:
NET API
PID = 600 mm (Inner Pipe Diameter)
MCR = 0 mm (Minimum Curve Radius)
ACMan = 0.015 (Manning Coefficient)
ACHW = 0 (Hazen Williams Coefficient)
ACDW = 0 (Darcy Weisbach Factor)

The manning Coefficient is "ACMan". The pipe Diameter is "PID".

Now, use the command CSETPAR:

Command: csetpar
Enter property name: ACMan
Inform new value: 0.015
Select objects: all
386 found

Another example:

Command: CSETPAR
Enter property name: PID
Inform new value: 800mm
Select objects: 1 found

It may be also that the property you want to set is not available in the pipe or structure. For example, If you use the default catalog of Civil 3D, property AreaContr (catchment area) not available in Structure Properties.

For it appears, see this topic. Create property:

<AeccDfParameter
name="AreaContr"
desc="Área de contribuição"
context="AreaContr_"
index="0"
datatype="Float"
usage="Double_Area"
unit="m²"
visible="True"
internal="True" />

Add the property to the catalog:

<AeccOptParam context="AreaContr_" />

Note that values ??that may have units of measurement can be informed to her. Otherwise the standard unit catalog is used.
