When you add a spray head manufacturer, series, and model to represent the project spray heads, all nozzles and options for that model are automatically available for input into the drawing. The heads will also automatically have all of the performance data conforming to the manufacturer’s specifications, and all symbols setup for placement.

Select the radius of the nozzle you wish to place: select the dropdown number icon on the Place Head toolbar. While a number of spray radius amounts are indicated on this dropdown, only those that apply to the specific manufacturer’s product selected will have data available.
|
For example, select Turf Spray, 12’ radius, and quarter arc nozzle. When you place the head into the drawing, several things happen:
Placing adjustable arc nozzle heads is a three step process. After selecting the radius and adjustable arc nozzle, click on the location for the head, then two points to define what the adjustable arc will be. The arc is defined in a counter-clockwise direction.
F Remember: Each head inserted will not only have the radius to match the manufacturer’s performance data, but will also automatically have data attached to it for the GPM flow requirements listed by the manufacturer for the design pressure. Adjustable heads will have flow data based upon each degree of arc entered.
When you add a manufacturer's model to a project, the strip sprays for lawn and shrub are automatically added along with the standard and adjustable nozzles.
Strip Spray pattern nozzles are selected in a little different manner from standard spray heads. You don’t use the turf or shrub, radius, and arc selector. Instead, selecting the Select Special Spray button lets you pick the desired head within a separate dialog box.
Select the turf or shrub model, in this case the 1804 for turf or 1812 for shrub, and then the strip spray desired. Rain Bird has five 4’ wide nozzles (15CST, EST, SST, LCS, RCS), a 9’ SST, and 8’ flat heads.
Select Place to place the end strip head (15EST) on the drawing. Notice that the target is representative of the width of the spray pattern of the strip spray, but when the head is placed, the complete rectangular pattern for the strip spray is indicated.

When you add a rotor spray head manufacturer, series, and model to represent a rotor head type, all nozzles and options for that model are automatically available for input into the drawing. The heads will also automatically have all of the performance data conforming to the manufacturer’s specifications, and all symbols setup for placement.
Selecting the Place Rotor icon will display the Select Rotor dialog box. This will list all of the rotor models, shrub and turf, that you added to the project. When you highlight a model, the available nozzles will be displayed to the right.
If you wish to view the manufacturer's performance data for the highlighted model, click on View Data. For example, highlight the Hunter I-40 and select View Data. The performance data will be displayed through your Web Browser.
Viewing the performance data is a helpful tool for making decisions on which nozzle is best suited for the Designers requirements. Having the data available through the Land F/X database simplifies, organizes, and speeds up the decision making process of selecting irrigation components.
As an example select the Place Rotor icon, and then highlight the Hunter I-40 Turf Rotor. The Model indicates the Hunter I-40-ADS, 36S, which is an adjustable arc and 360 arc nozzle with stainless steel riser and check valve. This was the model option selected when adding the head to the project.
Notice that the nozzles available are the 40 through the 43 nozzle. The performance data above also indicates a 44 and 45 nozzle. These are not listed because the design PSI selected for this head at the time of adding it to the project was 50 psi. The manufacturer does not list a performance value for the 44 and 45 nozzle at 50 psi (as this is not enough pressure to properly operate those nozzles), so Land F/X will not allow these nozzles to show up when the head is highlighted.
Select the 42 nozzle and click on Place for insertion into the drawing. The radius target for the head will appear on the crosshairs for head placement.
Click on the location for the head and, if this is an adjustable nozzle, select the two points for the arc pattern. The two points must be in a counter clockwise direction. The symbol will be inserted, with the nozzle number and offset from the location selected, and the arc pattern will be indicated.
As mentioned above, if you are entering an adjustable arc of the nozzle selected, click on two points for its arc pattern. If you are entering a full circle arc, simply right click and a full circle nozzle symbol and nozzle pattern will automatically be entered.
You can now insert a square or rectangular grid to serve as a template for placing the remaining heads in the soccer field (see following section).
Place the adjustable heads along the edge by selecting the two points for the arc definition in a counter clockwise direction. For full circle heads, simply right click.
Grid Templates can be inserted at any time as an aid for laying out heads. Grids can be triangular or square, and are accessed from the Place Head icon menu group.
The objective of the grid template is to place a temporary grid on the drawing in a quick and easy fashion to aid in the placement of heads. Zoom out to see the area you want the grid to occupy. Select the appropriate grid pattern, either square grid or triangular grid. The command line will ask:
If numbers are indicated in the < > default area, in this case 47.0, it is because that is the spacing of the head type you used last. This allows a quick default value for the grid spacing while you are placing heads, which you can accept with a right click of the mouse, or type in the spacing desired.
In this example right click or press enter to accept the default for the grid spacing, and the command line will ask:
To indicate the angle at which you want the grid to be drawn, you can select any object, such as any line on the drawing or in an Xref, or type in an angle, press Enter to select default of “0”, or click on any point in space to indicate an angle with a rubber-band line.
Once you have selected the angle of the grid, the command line will prompt:
Once you select any corner, the system will dynamically draw a grid as you move your mouse. At no point will the distance between grid lines ever be greater than the earlier specified Maximum Grid spacing. When you are satisfied with the size of the grid, simply Right Click, and the grid will be converted into a block that you can further move if necessary, or easily delete.
When placing heads, sometimes you know you need to place more of a head that is already placed. In many cases, it is faster to select the Match Head button to continue placing heads like the one specified, rather than selecting that style head from the toolbar.
Select the Match Head button from the Place Head floating toolbar, and then select any head, either spray or rotor. The system will then prompt you to place more of that head, just as if you manually selected that head using the previously mentioned techniques. Note that even if you click on a Full circle rotor, you will still be prompted to indicate the angle of the rotor, just as when you first placed the rotors. Likewise, spray heads will still prompt for their rotation angle, or spray angle if you selected an adjustable.
Once placed, heads can be copied along a straight line, insuring appropriate spacing between each one. This can dramatically speed the process of placing heads.
Click any head, and you will be prompted with a radius preview, rubber-banded to the selected head's insertion point. Indicate the placement of the last head, and that head will be copied along a line, maintaining no more spacing than its design radius. Note that Copy Head will also work with strip sprays, though obviously only center or side strips, not end strips. When used with Bubblers, the system will ask you to specify the maximum spacing between each bubbler
The Match Properties button functions similarly to the AutoCAD Match Properties command, in that it allows you to convert any number of destination heads to be the same as the selected source object.
The system will prompt you to select a source object, and then any number of destination objects. Note that it will function on any block, so it can be helpful to convert a plan done without Land F/X. Also, it sets the Undo marker in between each change, so that you can easily exit the command and then Undo back each individual change as necessary.
The Head Info button allows the user to see what model, flow, and Design Pressure any selected head is. This can be helpful in familiarizing oneself with a plan, or to see what flow an adjustable spray head requires. It also allows editing the Design Pressure, description, or nozzle.
Select the Head Info button, and then click on any head. You will see the Head Info dialog box indicating the type of head, manufacturer, model, nozzle, Design Pressure, and amount of flow.
You can edit the Model and Schedule Description, which will affect all heads in this family. Likewise, a change to the Design PSI will affect all heads of this model. While a change to the Nozzle will only affect the one head selected.
