Multiple or Duplicate Pipe Instances in Irrigation Schedule


You ran an Irrigation Schedule and noticed a large list of duplicate pipe entries of the same size, as pictured to the right.

Other equipment duplicated?

Is your schedule showing multiple entries for other types of equipment with duplicate symbols and quantities? If so, here's what to do.

Irrigation Schedule showing large list of pipe entries of the same size






This issue can result from:

  • A bug that has caused the XML data file for your Pipe Data to replicate sizes when checking the data it was using, and/or
  • An issue with your Preference Set pipe data, as well as any project data file that originated with the problematic Preference Set



Step 1: Check for and address a possible XML bug.

1A. Navigate to your LandFX folder, and go to the following location: LandFX/data/xml.cache



1B. Delete all files from within that folder.

Deleting all files from the folder LandFX/data/xml.cache



1C. Restart CAD and regenerate your schedule.


Still seeing duplicate pipe entries in the Irrigation Schedule? If so, move on to the next step.




Step 2 (if necessary): Address a possible issue with your Preference Set and project data.

If you're still having the issue, your next step should be to correct the LFX (.lfx) file(s) associated with any plan where you're seeing duplicate pipes in the schedule. These fixes will take in the source LFX file outside CAD.

You'll need to make the following changes in both the Preference Set and project data files before trying to run a new schedule.




2A. Back up the LFX files for your Preference Set and project.

For the Preference Set:

Open any of our Preferences screens.


Select the correct Preference Set, then click Manage.


In the Manage Preference Sets dialog box, click Backup.


When prompted, save the LFX Preferences file to your desktop.

Backing up a project data file
For the project data file:

Open your Project List.


Select the correct project for your plan, then click Backup.


Select the option to Backup to a Land F/X project.


Click OK, then save the file to your desktop.




2B. Make temporary backup copies of the LFX files.

Go to your desktop and locate the two LFX files you saved in the previous step. For safety purposes, make a backup copy of each of these files just in case something goes wrong in the editing process and you need to restore an original version of these project and Preference Set files.




2C. Adjust the newly downloaded LFX files.

Right-click each of the two LFX files you saved on your desktop, and open them using a text editing application such as Notepad.




With the text file open for each LFX file, press the CTRL + F keys to activate the Find command.


Search for MAINPIPE.


Delete each section of text that contains the term MAINPIPE.


In this example, we would delete the entire section beginning with <projdata> and ending with </projdata> because this section contains the term MAINPIPE.

The text file may contain multiple sections that include the text MAINPIPE. To eliminate the duplicates, take care to delete all these sections.

Save the changes to both LFX files.




Restoring a project data file

Open your Project List again, then click Restore.


Click Import in the Restore Project dialog box.


Select the LFX file you just adjusted from your desktop.




Click OK in the Enter Project Number dialog box.


Then, when asked if you want to overwrite the existing project, click Yes to overwrite it.

Selecting a project number and clicking OK


Clicking Yes to overwrite and existing project




Opening the Pipe Data dilaog box and clicking the Mainline tab

Open the Irrigation Manager, then click Pipe Data to open our Pipe Data tool.


In the Pipe Data dialog box, click the relevant tab for the pipe type that is duplicating in the schedule. In our example, we'll click the Mainline tab. This step will allow the system to generate the defaults.


Now run a new Irrigation Schedule (or regenerate the existing schedule). All pipe duplicates should now be removed.
