Irrigation

The irrigation tools (Vectorworks Landmark required) in the Site Planning tool set insert generic drip emitters, irrigation heads, and irrigation lines into the drawing.

A selection of standard pre-configured manufacturer’s irrigation products are available through the Resource Browser, and are located in the default irrigation libraries from the [Vectorworks]\Libraries folder that is included with the Vectorworks Landmark product (see “Resource Libraries” on page 215).

Inserting a Drip Emitter

A generic drip emitter can be inserted into the drawing with the Drip Emitter tool. Alternatively, use a drip emitter from one of the irrigation object libraries.

2. Click in the drawing to insert the drip emitter. Click again to set the rotation.

The first time the tool is used, the Drip Emitter Properties dialog box opens. Accept the default parameters and click OK to insert the drip emitter.

Parameter	Description
Manufacturer	Displays the manufacturer’s name or “Generic”
Model	Displays the manufacturer’s model number
Type	Options include Pressure Compensating and Non-Pressure Compensating
Head Style	Selects the type of emitter head (Micro-Spray, Drip Manifold, or Sub-surface Drip)
Spray Nozzle	For Micro-Spray head style, indicates the arc degrees of spray
Working Pressure	Displays the water line pressure, for use in worksheets
Flow Rate	Displays the flow rate per hour in either metric or imperial units
Unit	Selects the units for the display of flow rate
Scale Factor	Determines the size of 2D drip emitter display
Microtube Control	For Sub-surface Drip head style only, displays the coordinates of microtube placement. Coordinates 1X/Y position the control point that defines the microtube’s Bézier curve; coordinates 2X/Y position the control point that defines the microtube’s end point. Alternatively to entering coordinates, you can position the control points manually. The Sub-surface drip emitter contains control points in the center of the symbol; position the first control point to determine the microtube end point, and the second to define the curvature.

Inserting an Irrigation Head

A generic irrigation head can be inserted into the drawing with the Irrigation Head tool. Alternatively, use an irrigation head from one of the irrigation object libraries.

2. Click in the drawing to insert the irrigation head. Click again to set the rotation.

The first time the tool is used, the Irrigation Head Properties dialog box opens. Accept the default parameters and click OK to insert the irrigation head.

Parameter	Description
Manufacturer	Manufacturer’s name or “Generic”
Model	Manufacturer’s model number
Spray Pattern	Selections include Circular, Rectangular, and Special
Head Type	Indicates a Fixed Spray or Rotary sprinkler
Body	Spray head height (for use in worksheets)
Nozzle	Manufacturer’s nozzle type
Spray Radius or Width	For circular spray patterns, displays the radius of the spray; for rectangular spray patterns, displays the spray width
Length of Rect Spray	Displays the length of a rectangular spray pattern
Show Spray Pattern	Select to display the irrigation spray pattern
Spray Arc	Indicates the arc of the spray pattern and determines the spray pattern display
Trajectory	Angle (in degrees) of water as it is thrown from the spray head (for use in worksheets)
Working Pressure	Water line pressure (in psi or kg/cm3) for use in worksheets
Spacing	Indicates triangular or square spacing
Precipitation Rate	Number of inches or millimeters of water placed over a certain area per hour, for use in worksheets
Head Scale Factor	Determines the size of 2D irrigation head display
Unit	Specify either Metric or Imperial units

Inserting an Irrigation Line

An irrigation line can be inserted into the drawing with the Irrigation Line tool. Alternatively, use an irrigation line from one of the irrigation object libraries.

The first time the tool is used, the Irrigation Line Properties dialog box opens. Accept the default parameters and click OK to insert the irrigation line.

Parameter	Description
Length	Displays irrigation line length
Type	Indicates the irrigation line material (PVC, PE, Galvanized Steel, or Copper)
Diameter	Displays irrigation tubing diameter
Has Sleeve	Select if the irrigation line has a sleeve
Sleeve Diameter	When the Has Sleeve option is selected, indicates the tubing diameter of the sleeve

Show/Hide Spray Pattern

The Show or Hide Spray Pattern command controls the visibility of the spray pattern of irrigation head objects.

2. If the spray patterns are currently hidden, this command causes the spray pattern of all irrigation head objects to become visible. In the Object Info palette, Show Spray Pattern is selected automatically.

If the spray patterns are currently visible this command causes the spray pattern of all irrigation head objects to become hidden. In the Object Info palette, Show Spray Pattern is automatically deselected.
