Introduction

The CSD Pipes module of Civil Site Design software requires the Designer to setup what pipes & pits are available, how they want the software to perform and how objects are displayed for a specific drawing (or project).

The Active Network Settings form includes multiple tabs for control over the following functionality and object display:

Pipe, Box Section, Service Obstruction and Pit tables including geometric and hydraulic properties;

Object layer & labelling display controls;

Object snapping tolerances settings;

Drainage rainfall table definition (IDF & Log co-efficient);

Sewer design tables and House Connection definition;

The Active Network Settings is used to control the settings for the current drawing only, also referred to as Local Settings.

The initial settings for this form are populated from the selected Global Network Settings when a project is first started.  The Global Network Settings command is used to edit a Global Network Settings file.

Details

Upon selecting the command the following form is displayed:

The Active Network Settings is broken up into several main tabs: (Click on a tab for more information about that tab):

OK Apply and exit.

Cancel Exit the form without deleting any data.

General Tab

The General tab is used to configure project settings common to all network types (Drainage, Sewer and Services Obstructions).  It is divided up into the following tabs (Click on a tab for more information about that tab):

Defaults Tab

The General - Defaults tab is used to configure the surfaces, object snapping and pipe default geometric, hydraulic and clearance properties.

Note:  To adjust the focus to show information about a different tab, just click on the tab of interest.

Surfaces Select the surface (terrain) models that are used as the Existing and Design surfaces for the project.

  Existing Select the surface to be used as the Existing surface.

  Design Select the surface to be used as the Design surface.  The surface must exist for all pit and pipe locations.  The Design Surface is used for calculating pipe cover and is the default surface used for locating the top of pits.

  Pit Snap Distance Set the distance (in drawing units) to snap when selecting a pit.

  Pipe Snap Distance Set the distance (in drawing units) to snap when selecting a pipe.

  Maximum Search Distance From Road Centreline to Locate Pit Set the maximum distance (in drawing units) from any Road centreline the software will search for when locating a pit.  When a pit is being created and a location is specified within the search distance to a road, the user will be given the option to associate it to the Road.

  Minimum Distance Between Pits Set the minimum distance (in drawing units) between pits.  If the minimum distance is violated when locating a pit the user will be prompted with a warning message.

  Road Code to Locate Drainage Pit in Plan Specify the default Road Code to locate a drainage pit.  The code must be entered without the L or R prefix.

  Road Code for Top of Drainage Pit Specify the default Road Code the top of a drainage pit is associated with.  The code must be entered without the L or R prefix.

  Confirm Selected Network Enables or disables the Confirm Network when selecting a network.

  Confirm Selected Line Enables or disables the Confirm Line (or Branch) when selecting a line/branch of a network.

  Confirm Pit from Road Enables or disables the Confirm Pit from Road when creating pit associated with a road.

Note:  In the Road List, offset is distance first, followed by the Chainage, then the Alignment Name.

  Confirm Selected Pit Enables or disables the Confirm Pit form when selecting a pit.

  Confirm Selected Pipe Enables or disables the Confirm Pipe form when selecting a pipe.

  Road Code Top of Kerb (Flow Width Calcs) In order to determine the road extents within which to calculate the water depths at pits, users need to specify a Code from the Road cross sections that represents the outside edge for depth calculations.  Normally this would be the top of kerb (TK) or back of kerb.  Users can set this code themselves here.

  Ignore Legacy label plotting Traditionally, pit and pipe labels were automatically drawn as pipes and pits were created, for drainage and sewer networks.  Since Civil Site Design V16 new labelling tools are available, enhancing the drafting control of text, symbols and linework associated with the labels.  The Network Labels command can be used for this newer labelling - if this is planned, then the older (duplicate) labelling is probably not required.
