Limiting Irrigation Schedules Using Work Areas or POCs

In some cases, you may want to generate an Irrigation Schedule for only a portion of your drawing. Creating Work Areas in your drawing allows you to place a schedule for equipment contained within one or more Work Areas. For projects with more than one point of contact (POC), you can also create a schedule showing only equipment connected to a specific POC.

To learn more about creating Work Areas in your drawing, see our Work Areas page.

Work Areas and Irrigation Schedules: Overview

A Work Area is essentially a "drawing within a drawing" surrounded by a visible border. You can select a Work Area and perform specific functions on only that Work Area, rather than on the entire drawing. You can also create an irrigation schedule for several, or all, Work Areas in your drawing.


This feature can be especially valuable when you generate an irrigation schedule. Work Areas allow you to run separate schedules for:

  • A specific portion or phase of the project
  • Off-site and on-site improvement
  • Scope-of-work requirements (for example, certain areas designated as containing tenant improvements, other areas under a general contract, etc.)



Work Areas are drawn with a non-plot line, and the line color from one to another will vary slightly to distinguish them from one another.


A Work Area will appear on a single layer of your drawing. Once you are ready to run schedules for your entire site, you can simply Freeze each work area's layer. The schedule will not consider the Work Areas you've frozen.

In response to client requests, we've added the ability to create nested Work Areas – that is, Work Areas within Work Areas. Irrigation Schedules will now recognize objects within these nested Work Areas.


You may choose to create Work Areas before you begin designing your site. These Work Areas will provide pre-defined planting sites within your drawing, such as back and front yard areas, or project phases. When you're ready to create your separate irrigation schedules, you can simply select which Work Areas you want to include in the schedule.



Of course, you won't always know which parts of your site design you will need to include in a schedule until after you have started – or even completed – your drawing. In these cases, you can also create a Work Area of an existing portion of your drawing. You can then run an Irrigation Schedule for only items included in that Work Area.

Limiting the Irrigation Schedule to One or All Work Areas

The image below shows two separate Work Areas, titled Irrigation Sector 1 and Irrigation Sector 2, drawn within a larger irrigation plan.


Example of an irrigation plan with Work Areas


Because we've created separate Work Areas for these portions of the project, we can then generate a separate Irrigation Schedules for each work area.



If you generate an Irrigation Schedule for a drawing with multiple work areas, the cursor will turn into a pickbox and the CAD Command line will prompt you to:

Select Work Area or <All>.

If your project has only one point of connection (POC), you have two choices at this point:

  • Select Work Area: Use your pickbox to select one Work Area and, as a result, create an Irrigation Schedule reflecting only the contents of that Work Area.
  • <All>: Press Enter or right-click to produce an Irrigation Schedule for all Work Areas in the drawing.



Click the bounding line of a Work Area to select that Work Area. The Command line will prompt: Upper left corner.



Click to place the Irrigation Schedule. A schedule listing only equipment included in the selected Work Area will appear in that location.



Creating an Irrigation Schedule for our example Work Area Irrigation Sector 1 will generate the following result.

Creating an Irrigation Schedule Organized by Some, but Not All, Work Areas

Want to include more than one, but not all, Work Areas from your plan in an Irrigation Schedule? Follow our instructions to run a single schedule categorized by Work Area.

Work Areas and Hatches

Our software does not allow you to split a single hatch (such as a drip area or irrigation zone hatch) between multiple Work Areas. Splitting hatches in this way is not possible for a number of reasons – primarily because the only way to do so is to convert every hatch to a Region object, and then perform a Union and Subtraction against the Work Area in order to determine the area inside vs. outside the hatch.


This process can misfire because not all hatches can be converted to Region objects. Allowing splitting of hatches would require the software to highlight those areas in some fashion to alert users to them. But more importantly, that process of converting to Regions and Union/Subtracting takes time. For a complicated design with hundreds of areas could easily chug the computer for a number of minutes. While of course some users would be willing to accept that hit, we feel it's a bit beyond the acceptable range of about 7 seconds for the computer to finish doing whatever it was doing.


Even more importantly, splitting jobs into zones or phases typically coincides with a desire to turn off or half-tone the objects outside of the current viewport. In order to do this, you would need to draw the hatch as two separate hatches.


But after all of that explanation, we do believe that the ability to split hatches between Work Areas would be a handy feature to include in the software! In the future, as the Region functions become more reliable and a bit quicker, we will certainly be adding this functionality.

Editing a Work Area Name to Change a Schedule Title

When you create a Work Area, one of the steps is to type a name for it. The name you select will also appear in the name of an Irrigation Schedule you generate for plants within that Work Area. If you want to change the title of the Irrigation Schedule, you'll need to delete the existing schedule and rename the Work Area. When you re-place the schedule, it will include the new Work Area name. For specific instructions, see our Edit a Work Area Name to Change a Schedule Title article.

If your Work Area has a scale linked to it, simply change the name – not the scale. When you place a new schedule, it will feature that new name.

Limiting the Irrigation Schedule to a Specific POC

If you generate an Irrigation Schedule for a drawing with multiple points of connection (POCs), the cursor will turn into a pickbox and the CAD Command line will prompt you to:

Select POC or Work Area, <All>.



If you want, click a POC to select it. In the example below, we could select any of several POCs in the drawing, indicated by green checkered circles. The Irrigation Schedule generated in this example would list only equipment connect to the selected POC.

Once you select a POC, the Command line will prompt you to select an Upper left corner.



Click to place the Irrigation Schedule. A schedule listing only equipment connected to the selected POC will appear in that location.

Work Areas in Xrefs

Our software now recognizes Work Areas within Xrefs. That means you can run a schedule that includes plants, irrigation equipment, or site amenities within Work Areas that exist in files you've attached to the main drawing. When you go to generate your schedule, you can simply select individual Work Areas in your Xrefs as if they are in the current drawing. If you select All Work Areas, Land F/X objects within Work Areas in your Xrefs will be included in the schedule as if those Work Areas were in the main drawing.


For more information and specific instructions, see our Work Areas in Xrefs page.

  • Using Work Areas: Work Areas provide a perfect way to organize your schedules, scales, layers, and User Coordination Systems (UCSs). Whether you need to separate out phases in your schedules or show an area at a different scale and viewing angle, you need to know how to manipulate a Work Area. (1 hr 2 min)

General Work Area troubleshooting


Issue: Your Irrigation Schedule is not recognizing a Work Area, or is showing all plants or irrigation equipment in the drawing except those in a specific Work Area


Issue: The Irrigation Schedule tool is not giving you the option to select your entire drawing. It is only allowing you to run a schedule for one or more Work Areas.


Issue: Work Areas are not recognizing or calculating a hatch


Issue: You are unable to create or place a Work Area

Issue: "Cannot find Work Area title" error message when placing an Irrigation Schedule in a drawing with Work Areas


Issue: You tried to create an Irrigation Schedule for a Work Area in your drawing, but the schedule did not appear when you tried to place it


Issue: The pipe counts are incorrect in one or more of the Work Areas in your irrigation design
