Placing & Editing Hatches

Whether you need to place a large area with data attached to it (such as a planting, hardscaping, or irrigation area), or just a generic region in your drawing represented by a specific pattern, hatches play a vital role in our software. Find out how to put our hatching system to work for you.

Want information on customizing hatch patterns? See our documentation on Hatch Patterns and Saving a Hatch.

Hatch Types

Placing a Generic Site Hatch

Our generic site hatching tool provides a quick way to place a hatch if you need to create a site area consisting of mulch, concrete, or hardscaping materials such as pavers, but don't necessarily need to assign that area with data (such as per-unit cost).


Open the Hatch tool:



F/X Site ribbon, Hatch flyout


F/X Site ribbon, Hatch flyout



Graphics toolbar


Graphics toolbar

F/X Site menu


F/X Site menu, Hatch option



or type FX_SiteHatch in the Command line




The Hatch dialog box will open.



With Site selected in the list of hatch types, select a hatch to place.



The hatch thumbnail you select will turn white when you select it, as shown to the right.



Click OK to begin placing the selected hatch pattern in your drawing.

Placing a Generic Detail Hatch

Our hatch library includes several hatch patterns designed specifically for building your details. More information




Placing Smart Hatches (Planting, Site, Irrigation)

Hatches are ideal for representing smart objects in your drawings that need to be placed as contiguous areas rather than individual objects – for example, groundcovers and hardscaping areas. Here are a few examples:

When you place one of our smart hatch types, you may see a few extra options in the Command line specific to placing that particular smart object. However, the steps below for placing hatches apply loosely to placing any hatch within the Land F/X system.

Placing a Hatch: Overview

After you select a hatch to place, the cursor will turn into a pickbox, and the Command line will prompt you to Select polyline or interior point to hatch, [Draw Exclude shrubs Multiple]



Selecting an Existing Boundary

To select an existing polyline, use the pickbox to select a closed polyline area to hatch.



In this example, we'll hatch the kidney bean–shaped closed polyline pictured below.


Closed polyline to hatch, example




The polyline will be hatched with the pattern you selected.

Drawing a Hatch Boundary "On the Fly"

If you haven't yet drawn a polyline boundary for your hatch, you can now do so "on the fly" after selecting your hatch pattern.



When you go to place a hatch, the Command line will prompt you to Select polyline or interior point to hatch, [Draw Exclude shrubs Multiple].



Start drawing your closed polyline. Once you close it, the hatched area will appear within the polyline boundary.


Hatch placed

In previous versions, drawing your hatch boundary on the fly would require you to first type D for Draw. We've now built in the ability to simply start drawing your closed polyline. As long as the first point you select isn't an existing polyline, the Draw command will be fired automatically.


This feature works with all our default hatch types, including:


Scaling a Hatch Manually

Hatches not appearing at the scale you want them to be? Even though our software scales hatches automatically, you may want to adjust the scale of a hatch you've placed. You can easily do so by selecting the hatch and adjusting the scale in the Hatch Editor.


Double-click the hatch in your drawing. The Hatch Editor will open.


Scaling a hatch manually

Change the Scale value to a number that will give you the scale you want. 


A larger number will result in a hatch that's less dense. A smaller number will result in a denser hatch.


In this example, we'll change the scale of a hatch from 12 to 20.




As a result, the hatch in the drawing will have a scale that's less dense.


You may need to play with the scaling a bit, adding different values until the hatch has the look you want.

Excluding Objects from a Hatch (The "Multiple" Option)

Reference Note hatches are also helpful when you want to hatch an area but don't want to hatch one or more objects lying within that area. This feature works similarly to the Exclude Shrubs tool, which omits groundcover hatch from shrubs within a planting area.

This feature will not work with stipple hatches. If you want to exclude interior objects from a hatch, you'll need to make sure that hatch is something other than stipple.


To exclude objects from a site hatch, you'll need to place the hatch as an Area/Volume Reference Note


Open the Reference Notes tool:


F/X Site ribbon, RefNotes flyout


F/X Site ribbon, RefNotes flyout



F/X Details ribbon, RefNotes flyout


F/X Details ribbon, RefNotes flyout




F/X Site menu


F/X Site pull-down menu


Graphics RefNotes toolbar

or type RefNotes in the Command line





The Reference Notes Manager will open.



To specify your hatch, click New.

Reference Notes Manager, New button




New Reference Note dialog box

The New Reference Note dialog box will open.



Select Area/Volume.

For specific information on Area/Volume Reference notes, see our Area/Volume Reference Notes documentation.




The Hatch dialog box will open.



Select a hatch pattern (example: LFX-FILTBD), then click OK.

Hatch dialog box




New Reference Note dialog box, Note field

Back in the New Reference Note dialog box, type a note for your hatch.



Then click OK.




Back in the Reference Notes Manager, select the Area or Volume Reference Note you just created (or any existing Area or Volume Reference Note you want to place).



Click Place to place the hatch in your drawing.

Reference Notes Manager, Place button




The cursor will turn into a pickbox, and the Command line will prompt you to Select Polyline to hatch, [Multiple].

Don't see the Multiple option at this point? You might be using the Stipple hatch pattern. Stipple hatches don't recognize interior objects, which will prevent you from selecting them. To be able to select and exclude interior objects, you'll need to select a new hatch pattern that isn't Stipple.


Type M for Multiple. The Command line will prompt you to Select outer boundary. Select the polyline surrounding the area you would like to hatch.


Select outer boundary


The Command line will now prompt you to Select interior boundary, <done>. Use the pickbox to select the boundary of any object you'd like to exclude from the hatch.


Select boundary to exclude


Cannot process multiple boundaries because the outer polyline includes loops.


Seeing this error message when trying to use the Multiple option while placing a hatch?


Here's what to do.

Cannot process multiple boundaries error message




Not seeing an error message but still unable to select interior objects? Here's what to do.


Continue selecting the boundaries of objects you'd like to exclude from the hatch.


Continue selecting boundaries to exclude



When you've selected all objects you'd like to exclude from the hatch, press Enter. The area will be hatched, excluding the objects you selected.

Editing Placed Hatches (Hint: Use Our P-Hatch Tool)

Quick video

Do you need to add to or subtract from an existing placed hatch in your drawing? If so, we recommend using our P-Hatch tool rather than the native CAD Hatch Edit command.


P-Hatch makes it easy to add to or subtract from hatches by "painting" the hatch pattern into your drawing using one of several possible "brush" patterns. It's also a safe way to edit placed hatches without compromising the hatch boundary.


It's especially important to use P-Hatch to edit hatched areas that contain individual blocks such as shrubs, site amenities, or generic blocks. We've seen some major issues result from the use of Hatch Edit for this purpose – especially when selecting individual shrubs or other blocks to trim the hatch beneath them.


The problem often arises when a user chooses the Add Boundary option within the Hatch Edit command and then clicks individual blocks that lie within the hatch in an attempt to remove the hatch beneath those blocks, commonly with Shrub Area hatches, which lack the options to exclude individual shrubs or other internal objects when placed. This practice can result in hundreds of small boundaries within the hatch boundary (a major cause of poor drawing performance), while also negating the overall Area property for the hatch.


In these cases, we strongly recommend using P-Hatch, which makes instant edits to the hatch pattern while protecting the hatch's boundary and area total.

Assigning a Real-World Scale to a Placed Hatch Pattern

You might want a hatch that shows pavers, wood planks, or other objects to appear at a scale where the hatch components show at the same measurements in your drawing as they would on the site itself. For example, you might have a hatch depicting 8-inch pavers, and you want the pavers to actually measure 8 inches in your drawing. If so, here's what to do.


Issue: Hatches are appearing as solid rather than patterns


Issue: Hatch preview slides (thumbnails) are incorrect – several slides are identical but have different names


Issue: When placing a site hatch, you are unable to see the Multiple option for excluding interior objects from the hatch, or you are unable to select interior objects to exclude (but you see the Multiple option)


Issue: Unable to see hatches or colorized plants in a 3D model (AutoCAD or Civil 3D)


Issue: When placing a hatch, you received the following error message: Unable to locate target hatch


Issue: AutoCAD crashes when you place a hatch – but only when the Land F/X menus are loaded


Issue: Bad DXF group (10) error when placing hatches


Issue: Colors are displaying incorrectly in Model Space


Issue: While working offline, you are unable to access hatch patterns you've already used. The thumbnail previews in the Hatch dialog box are blank.


Issue: You tried to use our PHATCH tool, but it deleted the existing hatch and left only a hatch where you attempted to place the brush


Issue: You tried to place a Stipple hatch pattern, but the hatch is placing incorrectly outside the polyline area


Issue: Your hatches are showing up incorrectly, or as random lines or solid colors
