Our Irrigation Symbols

When you place an irrigation component in a drawing, our software represents it with a symbol. Like our plant symbols, our irrigation symbols are available as blocks that come with your Irrigation F/X installation.

 

 

Our symbol library includes symbols for the complete range of options from all manufacturers in our database – not just the basic group of symbols you are used to using for one manufacturer. As a result, adding and placing symbols can become complicated. Moreover, our software also allows you to create different types of irrigation schedules with schedule symbol options for all manufacturers. Faced with this level of choices, you'll likely find it easier to simply use our symbols rather than adding or creating your own.

Our irrigation symbols download on demand. If you place a piece of equipment, the symbol should download as necessary.

For more information on our irrigation symbols, we encourage you to download and review our Irrigation Getting Started Guide, linked below.

Our Irrigation Symbols Drawing

Our irrigation symbols drawing is the master file that holds all our irrigation symbols. To download it, right-click the following link and select Save Target As or Save Link As from the menu).

 

We recommend saving this file to the folder LandFX/Admin, overwriting the existing file.

 

Guide to Our Irrigation Symbols Drawing

The Irrigation Symbol DWG contains 10 Layout tabs. The first four tabs show our spray head symbols. You'll also see tabs for rotors, point source (drip and bubblers), and equipment (valves, backflow, etc.), followed by tabs for the text description on customization of the symbols.

 

Here's an example page from the drawing, which shows some of the spray head symbols:

 

 

The first tab, Spray Heads 1, shows an example of the first four families of spray head symbols.

 

How to Use Our Irrigation Symbols Drawing

Plot the Irrigation Symbols Drawing using the LFX.ctb plot style – or with your revised CTB file if you've changed the line colors.

 

Print each layout tab to an 8 1/2" x 11" sheet of paper, and review the output of the symbols. These symbols are represented at the same size at which they'll appear in Paper Space. In Model Space, they'll be scaled for the scale you've set for the drawing.

 

Review each printed layout tab for:

  • The 10 spray symbol families. You'll need to make a decision on which of these families will apply to which type of spray head you add to a project. Note that you'll configure this setting on the fly rather than in the Irrigation Preferences.
  • The size of the symbols. Their printed size depicts how they will appear in the final Paper Space drawing. If you want them larger or smaller, you can adjust the size in the Irrigation Preferences.
  • The family associated with each group of spray heads.
  • The lineweights used on these symbols. If they are generally too thick or thin for your standards, follow our instructions for Editing Our Irrigation Symbols.

The Irrigation Symbols Library

Each of our irrigation symbol blocks is stored in its own DWG source file in the folder LandFX/Blocks/Graphics/Irrigation. The drawing files for each symbol type will be located in the folder with the corresponding name. For example, the folder spray contains all DWGs containing spray symbols.

 

Keep in mind that you may not see these files in this folder until after you've used them in a drawing.

 

 

 

Within the spray folder are the DWG files containing the spray symbol source blocks, along with the SLD and XML file for each symbol drawing.

Maintaining a comprehensive library of symbols is a huge undertaking, and we wouldn't wish it on anybody. Some examples of symbol requirements that have come up recently include the Rain Bird HE-VANs (and before those were the really handy SQ nozzles), the Hunter MP-3500, and the Toro Precision series. That's a lot of symbols to have to maintain continuously, and it takes a tremendous effort on our part. One of the really wonderful benefits of using our irrigation design software is the ability to spec any equipment and know that a symbol will be assigned automatically.

You can make minor edits to customize any of our irrigation symbol blocks. For example, you may want to change the lineweights or layer names and colors within our symbols to match your standards. You can also create or add your own irrigation symbol by overwriting the appropriate block from our library with the linework from your custom symbol. For more information, see our Adding Your Spray Symbols documentation.

 

 

 

Expanded Rotor Symbols Library

We expanded our collection of rotor symbols in 2019 to include rotating arc indicators and symbols.

 

• No Rotation:

These symbols consist of our original default rotor blocks. The symbol will be fixed, and will place with no rotation. This symbol type does not show spray direction.

 

 

 

• Arc Rotates:

 

These symbols include an arc that serves as a spray direction indicator. The symbol itself will place as you see it here, and the arc will automatically face in the direction of the spray.

 

 

 

• Symbol Rotates:

 

With these symbols, the symbol and arc are fixed, and the entire block – including both the symbol and spray arc – will automatically rotate to face in the direction of the spray.

For further information about these updated rotor symbols, see our updated rotor symbols documentation.

 

To see our updated rotor symbols, download our irrigation symbols drawing.

 

 

 

Expanded Rotary Symbols Library

As of 2020, rotary blocks are now using symbol families. You can choose from 8 families created by us, or create up to 49 additional families for your custom symbols.

 

You can choose which symbol family to assign to each rotary manufacturer. Note that:

  • Symbols in families 1–4 do not include attributes, and symbols in families 5–8 include attributes.
  • The rotary symbols now include spray arcs to indicate spray direction, which appear automatically when you place a rotor.

 

To see examples of how these symbols will appear when you add rotaries to your projects, see our documentation on adding rotary heads.

 

Here are a couple of examples of the new rotary symbols with spray arcs:

 

Want to continue using the old default rotary default symbols? Make sure the system variable USERi1 is set to 23 in each irrigation drawing file where you want to use the old symbols. After you've set the variable to this value, you won't be prompted to set a symbol family when adding rotaries in the Irrigation Manager, and the spray arcs will not be included when you place the symbols.

Our master Irrigation Symbols drawing is the best reference to see all rotary family styles together and see details such as naming convention. If you make changes to any of our default rotary symbols, it's a good idea to download the Irrigation Symbols drawing and make the same change there as well, for your reference.

 

 

 

Rotary Symbol Families and Other Options

Rotary heads now offer the following options:

  • 8 families in total plus the old default symbol set, plus the ability to create up to 49 of your own families:
    • R01
    • R02
    • R03
    • R04
    • R05
    • R06
    • R07
    • R08
    • R50–99 (allowance for custom created families)
  • Symbol arcs organized into 3 groups:
    • R1 (to be used for families 1–4)
    • R5 (to be used for families 5–8)
    • Any custom families created (50–99 series) – the system will auto-match and look for an RXX identifier to use as arc blocks for that given family.

 

 

 

Rotary Symbol Naming Conventions

Symbols:

  • LAFX (Land F/X prefix) -R01 (family identifier) -01 (symbol identifier)
    • Example: LAFX-R01-01

 

Schedule symbols:

  • LAFX (Land F/X prefix) -R01 (family identifier) -05 (manufacturer identifier) -0024 (symbol group identifier) _SS (schedule symbol suffix)
    • Example: LAFX-R01-05-0024_SS

 

Spray arc blocks:

  • LAFX (Land F/X prefix) -ARC (arc block identifier) -05 (manufacturer identifier) -01 (symbol group identifier) _SS (schedule symbol suffix)
    • Example: LAFX-R01-05-2400_SS

 

Family preview slides:

  • LAFX (Land F/X prefix) -R01 (family identifier) -05 (manufacturer identifier) -FAMILY (preview slide identifier) _SS (schedule symbol suffix)
    • Example: LAFX-R01-05-FAMILY

 

 

 

Updated Spray Symbols Library

As of 2021, our spray symbols library includes rotating arc indicators and symbols, much like our library of rotor symbols.

 

• Arc Rotates:

 

These symbols include an arc that serves as a spray direction indicator. The symbol itself will place as you see it here, and the arc will automatically face in the direction of the spray.

 

 

 

• Symbol Rotates:

 

With these symbols, the symbol and arc are fixed, and the entire block – including both the symbol and spray arc – will automatically rotate to face in the direction of the spray.

 

 

 

• No Rotation:

These symbols consist of our original default spray blocks. The symbol will be fixed, and will place with no rotation. This symbol type does not show spray direction.

 

 

 

To see our updated spray symbols, download our irrigation symbols drawing.

 

 

 

Spray Symbol Naming Conventions

Spray symbols now include a radius block and an arc block, much like rotor symbols.

 

Radius block:

  • LAFX-Family-Radius
    • Example: LAFX-N1-04
    • Example: LAFX-N8-15

 

Arc block:

  • LAFX-ARC-style-radius-arc
    • Example: LAFX-ARC-NW-12-180
    • Example: LAFX-ARC-NB-12-360
    • NW indicates the arcs for the Black on White heads (text numbers).
      • Layers/colors for the arc blocks: LK-IRRG-ARC

 

Symbol family # locations:

  • Arc Rotates:
    • 3 (N1)
    • 4 (N2)
    • 5* (N3)
    • 6 (N4)
    • 7 (N5)
    • 8 (N6)
    • 9* (N7)
    • 10 (N8)
      • * code is dropping arc indicator (from symbol code) to recognize arc rotate blocks
  • Block rotates:
    • 1 (S)
    • 2 (T)
    • (U): empty
    • (V): empty
    • (W): empty
    • X: User Defined
    • (Y): empty
    • (Z): empty
  • No rotation:
    • All existing (N) spray families (non-rotating)

 

Schedule symbols:

  • LAFX-Family and schedule suffix-Radius-number
    • Example: NA2S-12-9 (original naming example: N2S-12-9)

 

Each family type has a FAMILY DWG and slide file (SLD) that controls how you see your options. If you want to modify the display, open the folder LandFX/Blocks/graphics/irrigation/schedule_symbols and find the DWG file named:

  • LAFX-FAMILY-N-(family number)
  • LAFX-FAMILY-NA-(family number)
  • LAFX-FAMILY-S
  • LAFX-FAMILY-T
  • LAFX-FAMILY-X

 

If you want more rotating symbol options, you can create a file that matches the above names, with U-W, Y, Z, etc. as the suffix. (example: LAFX-FAMILY-U)

Our Symbol Block Naming System

As with our other symbols, our irrigation symbol blocks are named in such a way that the software knows what type of equipment a block represents based on its source file name – also the name of the block you see when selecting it as a symbol for a piece of equipment. We updated this file naming system in 2020 to provide a better organizational structure for our symbol block files. Note that you'll also need to respect these naming conventions when saving your custom symbol files into our system.

 

 

 

What Happens with Older Blocks Already Defined in Your Drawings

If you already any of our older blocks defined in your drawing, the system will continue using those blocks. If you start a new drawing and try to place anything, the system will attempt to place one of the new named blocks, which means it will download a second version of that block type, but named with the new name structure.

If you've modified these older blocks previously, you'll need to either:

  • Rename these custom blocks to fall in line with the new naming conventions outlined below, or
  • Copy the contents of each customized block into the new corresponding source block file and overwrite our existing content in that file

 

In either case, remember to run the MSLIDE command to create an appropriate preview slide of what that symbol looks like, so that when you pick that symbol from the Edit Equipment dialog box, you'll see the correct symbol slides.

 

 

 

The system will update existing blocks in a previous project (that is, a project that uses older defined blocks and older block names) in two main ways:

  • If you add equipment to a project, the system will auto-assign and download the new block for that equipment
  • If you click a preview thumbnail to change a block – that is, if you use our Edit Equipment tool and click an existing piece of equipment, and then click the thumbnail and select one of the symbols there – the block definition will update to that newly named block.

 

 

 

How Our Updated Naming Conventions Work

Here's how our updated symbol naming structure breaks down:

 

• Heads (other than bubblers): The naming of these symbols is based on the symbol family types. You can choose these symbols on the fly.

 

• All other symbols: Refer to the Equipment Codes guide below.

 

 

 

All Land F/X blocks will start with LAFX-, followed by the equipment codes listed below, followed by a three-digit number – for example: LAFX-BUB-001.

 

We number our symbols starting with -001, as pictured to the right.

 

 

 

Here are some examples of how our block names and symbols used to look for a handful of equipment types, and how they look now.

If you want to alter the corresponding files for these or any other blocks, feel free to do so. As long as you keep in line with the new suffixes outlined below, your symbols will show up in the correct section when you add any type of equipment.

    Selecting or Editing Symbol Blocks: Troubleshooting

    Running into one of the following issues?

     

     

     

     

    You selected an irrigation equipment block, and you can see that it’s using an old block definition, or …

     

    … you tried to use our Edit Equipment tool to edit a component, and the preview slide for the component was blank.

     

     

    In either of these cases, here's what to do.

     

     

     

    Saving Your Custom Blocks

    If you want to save your own custom irrigation symbol blocks into our system, just make sure the block names start with the prefixes listed above for the corresponding equipment. The rest of the block name can be whatever you like.

    Schedule Symbols

    The blocks for the schedule symbols heads are located in the folder LandFX/Blocks/Graphics/Irrigation/Schedule_Symbols. When running an Irrigation Schedule, you can organize spray heads in two possible ways:

    • By Group
    • By Nozzle

     

     

    When you run a schedule "By Nozzle," the symbol for each nozzle you've used will appear in the schedule. This option requires no special schedule symbol.

     

     

    When you run a schedule “By Group," the system will require a Schedule Symbol that relates to the options of grouping as applies to each manufacturer's requirements. Thus, in the case of 8’ radius spray heads, Rain Bird 1800 will require a group that lists four nozzles: Q, T, H, and F, whereas Toro 570 will require a group with six nozzles: Q, T, H, TT, TQ, and F. Each radius can have several options for schedule symbols, which appear to the side of the radius heads on the drawing.

     

     

     

    Schedule Symbols for Rotors & Spray Heads

    For rotors and spray heads, our default library of schedule symbols only includes the standard single symbol. If you want to use one of the updated four-arc symbols in your schedule, you can download these updated symbols using the link below.

     

     

     

     

    Once you've downloaded these symbols, save them into the folder LandFX\Blocks\graphics\irrigation\schedule_symbols.

    The Symbol Families

    Our Irrigation Symbols Drawing contains several "symbol families" for each type of irrigation equipment. Each family includes a number of related irrigation symbols, which will have a different structure, appearance, and organization particular to each equipment type.

     

     

    Symbol Sizes

    Our irrigation symbols were sized to fit into the space provided for them, along with at least a small length of pipe. This feature is especially critical for the smaller-diameter spray heads. We've sized our symbols with the following scales in mind:

    Up to 1”=20' scale: all symbols.

    1”=30' scale: all symbols with a 5' radius or greater.

    1”=40' scale: all symbols with an 8' radius or greater.

     

     

     

    An Example: The Spray Symbol Families

    To illustrate the general thinking behind our irrigation symbols, here's a breakdown of our spray symbol families. The descriptions below apply particularly to our spray symbols, but they should give you some idea of how we create and organize each family.

    Spray symbol families are no longer assigned by Preference Set. You can now select spray symbols on the fly as you would all other family types (e.g., rotors, rotary heads, etc.).

     

     

     

    The image to the right shows a few of the spray symbols in Family 3, which denote heads that do not rotate.

     

     

     

    The image to the left shows more of the spray symbols in Family 3. If you see a symbol with a similar appearance to one you'd like to see in your drawing, you can open the DWG file containing that symbol (see Symbol Library Organization below).

     

     

    The blue text below each symbol indicates that symbol's DWG filename.

     

    Note that each symbol has its own DWG file – even symbols with the same radius but a different spray range.

     

     

     

     

    Our spray symbol library also includes a family called Family X. We created this symbol family specifically to allow users to customize the symbols. The symbols in Family X are essentially blank, allowing you to make extensive changes to them. Note that they are organized by radius size.

     

     

     

    The spray heads in Families 1, 2, and 3 are diagrammatic. When placed into a drawing, they will all be rotated to match the direction in which their arc pattern is pointing. When you save them, they should be pointing due east. Open some of these with specific arcs, such as 1/4 or 1/3, for a visual example. Spray head symbols in families 1 and 2 are either circular or hexagonal, and Family 3 consists mainly of square symbols.

     

     

    The spray heads in families 4 through 11 do not rotate when placed, as each has a numerical value for its radius. Symbols in these families have either a black letter in a white background or a white letter in a filled background.

     

    All irrigation symbol blocks are located in the appropriate subfolders within the folder LandFX/Blocks/Graphics/Irrigation. For example, the spray head symbols are located in the folder LandFX/Blocks/Graphics/Irrigation/Spray. Each family lists the various radii and arc requirements. If you turn on the layer X-TEXT-013M, the AutoCAD file name for each symbol will appear below the corresponding symbol.

     

     

     

    Selecting Spray Symbol Families

    As mentioned above, your spray symbol families are no longer assigned according to the Preference Set you're using for your system design. Instead, you'll pick from the set of spray families on the fly in the same way you'd do with a rotor symbol. With this update, you won't be limited to 2 turf sprays and 4 shrub sprays – you can have as many of each as you want.

     

     

     

    For most projects, you can simply add a turf spray and a shrub spray. The families you select for Turf Spray and Shrub Spray will apply to the corresponding categories of heads the first time you add a turf or shrub spray to a project.

     

    The occasion may arise that you need to add an additional turf spray and/or additional shrub spray to a project. These items will be assigned to the symbol families selected for Turf Spray 2 and Shrub Spray 2. We also allow for occasions when you may need to add two more shrub spray types to a project; Shrub Spray 3 and Shrub Spray 4 are symbol families for these items.

     

    Note that we've removed the Spray Symbols section from the Irrigation Preferences, as you'll make all these selections on the fly rather than in the Preferences screen.

    Editing Our Irrigation Symbols

    Our irrigation symbols may be close in appearance to what you want ... but not quite. For example, their lineweights may be too thick or too thin for your office standards. For information on making minor edits to our symbols, please see our documentation page on Editing Our Irrigation Symbols.
