Irrigation Settings

Prior to beginning an irrigation design, set up the default irrigation settings. The irrigation settings apply to the current file.

Click Reset to return all irrigation settings to their default values.

To specify the irrigation settings:

1. Select Landmark > Irrigation > Irrigation Settings.

The Irrigation Settings dialog box opens.

2. Click the Units tab.

The unit and precision settings here override the Units specified in the document settings, and apply only to the irrigation components of the drawing. Specify the unit and precision value for the size (small dimensions of components, such as pipe diameter), distance (measurements for larger items such as throw distance), angle, pressure, flow rate, and velocity measurements. For any of the units of measurement except the angle, a custom unit can be specified; see Creating a Custom Unit System.

3. Click the Pipes/Tubing tab.

►    Click to show/hide the parameters.

Parameter	Description
Pipe Sizing
Pipe Additional Loss Factor	When using the Size Pipes command to set pipe sizes, enter an additional loss percentage to account for typical pressure losses due to components such as fittings. This additional factor is added to the calculated pressure loss value for the pipes.
Max Outlet Pressure Variation	When using the Size Pipes command to set pipe sizes, sets the allowable pressure variation between the first and last outlet in a line of lateral pipes
Main Line/Lateral Line	Each tab contains the default information for main line pipes and lateral line pipes
Default Pipe Type	Select the pipe material to be used for the majority of the pipes in the project
Maximum Velocity	Indicates the maximum allowable velocity for the pipes in the system; pipes must not exceed this set velocity
Default Trench Depth	Specifies the default depth for burying the system’s pipes, for informational purposes
Default Sleeve Diameter	Sets the default pipe sleeve diameter for the project
Sizing List	When using the Size Pipes command to set pipe sizes, indicates the pipes available for use in the irrigation system. Pipe sizes with a check mark in the Use column are available for use by the command if applicable. The selection made in the Default Pipe Type list determines which pipe sizes in the Sizing List display as available, or, if blank, not available. The list is also used by the Pipe tool to size pipes, when the Min Diameter Not Exceeding Velocity Limit option is selected.
Use All	Places a check mark in the Use column for all pipe sizes
Use None	Removes the check mark from the Use column for all pipe sizes
Drip Tubing
Default Pipe Type	Select the pipe material to be used for the majority of the drip tubing in the project
Default Trench Depth	Specifies the default depth for burying the system’s drip tubing, for informational purposes

4. Click the Zoning tab.

The settings on this tab apply to design zones (see Creating Design Zones). Select the zone numbering method, and then choose the classes for identifying overlapping coverage or areas without any coverage.

►    Click to show/hide the parameters.

Parameter	Description
Zone ID Numbering System	Specifies the method for automatically numbering the Zone ID parameter for design zones. A numeric or alphabetic method can be selected.
Coverage Analysis - coverage spray arc/pattern class	Assigns classes to the possible overlapping coverage situations for outlet spray patterns/arcs, for easy identification when performing a coverage analysis
No Coverage	For areas of the design zone where there is no spray pattern/arc coverage, select a class from the list of classes present in the drawing, or create a new class
One - Four	For each spray pattern/arc coverage situation, select a class from the list of classes present in the drawing, or create a new class. “One” coverage class indicates that an area is covered once, “Two” indicates one overlapping area, and so on.

5. Click the Classing tab.

The settings on this tab control whether the various irrigation objects, and in some cases, sub-objects, are automatically assigned to classes, and assign the class names to the objects. The assigned classes are created in the file as the objects are added.

►    Click to show/hide the parameters.

Parameter	Description
Automatic classes for irrigation objects
Use	A check mark in the Use column indicates that the irrigation object will be assigned to the indicated class. Either click in the Use column, or select the Use This Class For Irrigation Object option for the selected object.
Irrigation Object	Lists the various types of irrigation objects that can be created by the irrigation tools; select a row to edit the information
Class	Displays the class assigned to the irrigation object. Suggested class names are provided, based on the standard selected in Standard Naming.
Selected Item
Use This Class For Irrigation Object	Specifies whether to assign the selected irrigation object type to its designated class; this option is identical to the Use column check box
Class	For the selected irrigation object type, select a class from the list of classes present in the drawing, or create a new class

6. Click OK.
