Schematic Irrigation

Depending on your date of installation, the data in the Schematic Irrigation tool can sometimes be less than ideal. For this reason, before you place a Schematic area, it's important to check the precipitation rate and pressure assigned to that area to make sure they are accurate.

Before placing and using a Schematic area, select the corresponding Schematic type in the Schematic Irrigation Manager and click Edit.

In the Edit Schematic Irrigation Zone dialog box, check the Precip. and Pressure figures. If necessary, change them to reflect your intended rates.

You can also make any other necessary changes at this point by following our Configuring and Editing Schematic Types steps.

Click New in the Schematic Irrigation Manager to add a new Schematic type.

The Schematic Irrigation Area dialog box will open.

You can choose to:

• Create a custom Schematic type that will only show up in the active Land F/X project, or
• Select an existing type from a pre-populated list generated from the active Preference Set

To create your own project-specific Schematic type, you can simply type in all the necessary information, including the Title, Note, Precip and Pressure rates, and, if you want, Cost per square foot or meter.

To select a color or hatch to represent your new type when placed in your drawing, click the Symbol thumbnail and select your desired color or hatch.

Click OK to add your new Schematic type to your project.

For more information on configuring your Schematic type, see Configuring and Editing Schematic Types below.

You can also use the Title menu to see a list of all possible Schematic types you can add to your project. These types include all our default Schematic types, as well as any custom Schematic types you've created, and are saved in your active Preference Set.

Select an equipment type from the menu.

After you select an existing Schematic type, the data assigned to that type will autopopulate in the dialog box. In this example, we've selected the SHRUB AREA FOR DRIP EMITTERS – HIGH DENSITY type.

You can choose to edit the data assigned to this equipment type, including its hatch color, before adding it to your project. For more information on this data and how to edit it, see Editing a Schematic Type below.

Click OK to add the Schematic type to your project.

The Schematic type will now appear in the list of types in the SCHEMATIC IRRIGATION / CIRCUITING palette, ready for you to place in your drawing.

To edit an existing Schematic type, select it in the list and click Edit to open the Schematic Irrigation Area dialog box for that type (pictured below).

If you're adding a new type to your project and need to configure the data attached to it, you'll already be in this dialog box.

1. The Title of the Schematic type.

2. A detailed Note describing the Schematic type appears by default. You can edit and add to this note as you see fit, or type your own notes for project-specific types you create.

3. The data for the Schematic type: precipitation rate (Precip), design pressure (Pressure), and (optional) the construction Cost for this Schematic type.

4. The Symbol, or hatch pattern, that will represent this Schematic type.

We recommend reviewing the preset data for a particular Schematic type before using it.

Review the Title of the Schematic type to ensure it represents your intent.

The Note field contains expanded text that defines the title in more detail. You can choose to add to or edit this field as needed.

The precipitation rate (Precip) is important to review because its value will determine the flow defined for a selected area, using the following formula:

Flow (gpm) = (Area sf / 96.3) (Precipitation Rate)

Therefore, the Precipitation Rate determines the final flow in gallons per minute (or liters per minute) applied to the various Schematic areas. You may need an accurate portrayal of the flow required for your project. The rates indicated in the default types generally represent an average among several manufacturers of that type of equipment, so you may need to adjust the Precipitation Rate to meet your particular needs.

For a given Schematic type, such as SHRUB SPRAY, you might review the Precipitation Rate listed in the specific manufacturer’s performance data for the head type you plan to use, and either:

• Adjust the Precipitation Rate listed in the Schematic type, or
• Create a new Schematic type of a different title, such as "Shrub Spray Rain Bird 1800," for a very specific type of equipment.

Pressure: Review the design pressure you want for the head type, as well as the unit construction cost.

This figure may vary for different geographic areas. It may also vary depending on whether this unit cost is only accounting for the lateral system or is also including valves and mainline.

Cost: The default cost was intended to represent a commercial-grade unit cost for the lateral lines and heads only, with valves, mainline, controllers, etc. incurring separate unit costs

The default symbol for each Schematic type is a thumbnail preview of a solid hatch of a certain color.

If you want, you can click this thumbnail to select a new color for the Schematic type.

If you click the thumbnail, you'll be taken to the Hatch dialog box, which contains a library of possible colors for Schematic areas.

Here, you can select either a Truecolor or a hatch pattern to represent your Schematic type when you place it in your drawing.

The Truecolor tab will be selected by default. To pick a color for the selected type, click it and click OK.

You can also choose to assign a hatch pattern to the selected type. To do so, select the Site hatch.

You can then click one of the hatch patterns to select it, then click OK.

You can add to this library using our Save Hatch tool.

In the Schematic Irrigation Manager, select a Schematic type from the list.

Click Place to place the Schematic area.

To select an existing polyline as your Schematic area boundary, use the pickbox to select a closed polyline area where you want to place the Schematic area.

The polyline area will fill with the color or hatch pattern associated with the area you selected, and the flow total of that Schematic area will be shown in an MLeader callout either inside or near the area selected. For easy identification, he MLeader will be the same color as the Schematic area.

This MLeader will be on a non-plot layer, and you may want to click it and move it more to the center of your Schematic area.

You may want to replace the solid hatches in your Schematic areas with different hatches, such as a black-and-white pattern. If so, you can simply edit a Schematic area and change its hatch from a solid TrueColor to a Site hatch. More information

To delete a Schematic type, select it in the Schematic Irrigation Manager and click Delete.

If that type has been placed in a drawing, you may be asked whether you're sure you wish to delete it.

Click Yes to delete the Schematic type.

To import Schematic types from another Land F/X project or template, click Import in the Schematic Irrigation Manager.

In the dialog box that opens, select the project or template that includes the Schematic types you want to import, then click OK.

Select each Schematic type you want to import into your current project. You can select multiple types at once by holding down the Shift or Ctrl keys.

Click Add to Project to import the selected types into your project.

The Schematic types you imported will now be included in your project and listed in the Schematic palette.

To place a schedule showing all the Schematic types you've placed in your drawing, click the Schedule button in the Schematic Manager.

You can also use our Irrigation Schedule tool to generate an Irrigation Schedule and include your Schematic types.

The Irrigation Schedule dialog box will open.

In the Schematic Areas options at the bottom select the items you want to include in the schedule for your Schematic areas. Then click OK.

The Command line will prompt: Upper Left Corner. Click the upper left corner of the area in your drawing where you wish to place the schedule. The schedule will appear in your drawing.

Be sure to uncheck the boxes for any items in the Schematic Areas section that you don't want to include in the schedule, such as Cost.
