How to Use Hatch Command in AutoCAD – Complete Guide

Last Updated: August 29, 2026

The HATCH command in AutoCAD is used to fill enclosed areas with patterns, solid fills, or gradients. Hatch is commonly used in architectural, civil, structural, mechanical, and other technical drawings to visually represent materials, sections, or different areas.

For example, a floor plan may use hatch patterns to represent walls, a section drawing may use hatch to indicate cut materials, and a site drawing may use different fills to distinguish surfaces.

This guide explains how to use the Hatch command step by step, including practical examples, important settings, common problems, and useful tips.

Note: The appearance and available Hatch options may vary depending on your AutoCAD version.

What Is the Hatch Command in AutoCAD?

The Hatch command creates a pattern or fill inside an enclosed boundary.

You can use Hatch to create:

Solid fills
Standard hatch patterns
Material-style patterns
Section representations
Surface indications
Graphical distinctions between areas

The command is particularly useful because it allows a drawing to communicate information visually without adding unnecessary text.

How to Start the Hatch Command

There are several ways to start Hatch.

Method 1: Command Line

Type:

HATCH

and press Enter.

Method 2: Ribbon

Open the appropriate Hatch or Draw panel from the AutoCAD interface, depending on your workspace and version.

Method 3: Shortcut

You can type:

H

and press Enter.

AutoCAD will start the Hatch command in configurations where H is assigned to Hatch.

Basic Steps to Create a Hatch

Let's start with a simple example.

Suppose you have a rectangle representing a room or drawing area.

Step 1: Create a Closed Boundary

First create an enclosed shape using commands such as:

RECTANG

PLINE

The boundary must be suitable for hatching.

For example:

Rectangle = 4,000 mm × 3,000 mm

Step 2: Start Hatch

Type:

HATCH

and press Enter.

Step 3: Select the Area

Choose the area inside the closed boundary.

AutoCAD will identify the enclosed region.

Step 4: Select a Pattern

Choose an appropriate hatch pattern.

For example, you may use:

ANSI31
Solid
Other available patterns

Step 5: Adjust the Scale

If the pattern appears too dense or too large, change the hatch scale.

Step 6: Adjust the Angle

If necessary, change the hatch angle.

Step 7: Confirm

Finish the Hatch command.

The selected area will now display the chosen hatch.

Practical Example 1: Hatch a Concrete Slab

Suppose you have a rectangular slab:

Length = 5,000 mm
Width = 3,000 mm

You want to show the slab using a hatch pattern.

Workflow

Draw the rectangle.
Start HATCH.
Select inside the rectangle.
Choose an appropriate pattern.
Adjust the scale.
Check the preview.
Confirm the hatch.

The hatch now provides a visual indication that the rectangle represents a particular material or construction element.

The exact pattern used should follow the drawing standard or project requirements.

Practical Example 2: Hatch a Wall in a Floor Plan

Suppose you have a simple floor plan with wall boundaries.

You can use Hatch to visually distinguish the wall area from the room area.

Step 1

Make sure the wall boundary is properly closed.

Step 2

Start:

HATCH

Step 3

Select the wall area.

Step 4

Choose an appropriate hatch pattern or solid fill.

Step 5

Adjust the scale so the pattern is clearly visible.

Step 6

Confirm the hatch.

This can make a floor plan easier to read.

Practical Example 3: Solid Hatch

Sometimes a pattern is unnecessary and you simply want to fill an area.

For example, you may want to highlight:

A filled symbol
A column
A small section
A graphical area

In this situation, choose the Solid hatch option.

Workflow

Start HATCH.
Select the enclosed area.
Choose Solid.
Preview the result.
Confirm.

For very small areas, a solid hatch can often be easier to read than a detailed pattern.

Understanding Hatch Pattern

A hatch pattern determines how the selected area is filled.

Different patterns can be used for different graphical purposes.

One commonly encountered pattern is:

ANSI31

It produces a simple diagonal line pattern.

However, don't assume that one particular pattern represents a specific material in every organization.

Always follow the relevant drawing standard, office standard, or project specification.

Hatch Scale

Hatch Scale controls the spacing and visual size of the hatch pattern.

This is one of the most important Hatch settings.

Example

Suppose you apply a hatch and it appears extremely dense.

The pattern may be too small relative to your drawing.

Increase the hatch scale and preview the result.

If the hatch looks too widely spaced, reduce the scale.

Important

There is no universal hatch scale that works for every drawing.

The appropriate value depends on:

Drawing units
Drawing scale
Object size
Plot scale
Pattern
Project standards

Hatch Angle

Hatch Angle controls the orientation of the hatch pattern.

For example, a diagonal hatch may normally appear at one orientation.

Changing the angle can rotate the pattern.

Practical Example

Suppose two adjacent areas use the same hatch pattern but need to be visually distinguished.

You can use different hatch angles if appropriate.

This can make the drawing easier to interpret.

Hatch Transparency

Transparency can be useful when you want the underlying drawing to remain visible through a hatch.

For example, a transparent fill can be useful for visually highlighting:

Zones
Areas
Site regions
Design options

However, use transparency carefully because it can affect printed output and drawing readability.

Always check the final plot or PDF.

Associative Hatch

An associative hatch can remain associated with its boundary.

This can be useful when the boundary changes.

Example

Suppose you hatch a room boundary and later modify the boundary.

Depending on the hatch and boundary configuration, the hatch may update with the boundary.

This can save time compared with deleting and recreating the hatch manually.

Important

Always verify the hatch after modifying its boundary.

A complex or damaged boundary can cause hatch problems.

Hatch Origin

Hatch patterns can appear differently depending on their origin.

If two areas use the same pattern but the pattern alignment appears inconsistent, checking the hatch origin can help.

This is particularly noticeable when working with larger patterns or multiple adjacent areas.

Hatch Boundary Detection

AutoCAD can identify enclosed areas when you use the Hatch command.

However, the boundary must be properly enclosed for reliable automatic detection.

If AutoCAD cannot identify the area, check the geometry before assuming the Hatch command is defective.

What to Do When Hatch Does Not Work

One of the most common Hatch problems is:

"AutoCAD is not creating the hatch."

There can be several reasons.

Problem 1: Boundary Is Not Closed

The selected area may contain a small gap.

Solution

Check the boundary carefully.

Useful commands may include:

PEDIT
JOIN
TRIM
EXTEND

Close the boundary and try Hatch again.

Problem 2: Very Small Gap

Sometimes the boundary looks closed but contains a tiny gap.

This can prevent AutoCAD from detecting the intended area.

Solution

Zoom in closely around the boundary.

Check:

Corners
Line endpoints
Intersections
Polyline connections

Correct the gap and retry the Hatch command.

Problem 3: Hatch Pattern Is Too Dense

If the hatch appears almost completely filled with lines, the scale may be inappropriate.

Solution

Increase the hatch scale and preview the result.

Problem 4: Hatch Pattern Is Too Large

If only a few hatch lines appear across a large area, the scale may be too large.

Solution

Reduce the hatch scale.

Problem 5: Hatch Is Covering Other Objects

A hatch can visually obscure geometry depending on its configuration and draw order.

Solution

Check the hatch's draw order.

You may need to send the hatch behind other objects so that important geometry remains visible.

Problem 6: Hatch Is Not Visible

If you created a hatch but cannot see it clearly, check:

Hatch pattern
Scale
Layer visibility
Layer color
Hatch color
Transparency
Display settings

Also make sure the hatch layer is not turned off or frozen.

Editing an Existing Hatch

You don't necessarily need to delete and recreate a hatch when you want to change it.

Select the existing hatch and use the available Hatch editing controls.

Depending on your AutoCAD version, you may be able to modify:

Pattern
Scale
Angle
Color
Transparency
Boundary
Associativity

This is usually faster than starting over.

How to Remove a Hatch

If you want to delete a hatch:

Select the hatch.
Press Delete.

Alternatively, use:

ERASE

and select the hatch.

Be careful when selecting because a drawing may contain several overlapping objects.

How to Hatch Multiple Areas

You can hatch multiple suitable areas during the same Hatch operation.

Example

Suppose a floor plan contains several wall regions.

You can:

Start Hatch.
Select the first area.
Select additional areas.
Apply the desired pattern.
Adjust scale and angle.
Confirm.

This can be faster than creating each hatch individually.

Hatch and Layers

Using dedicated layers for hatch objects can make drawings easier to manage.

For example, a project might use separate layers for:

Wall hatch
Concrete hatch
Floor hatch
Section hatch
Site hatch

The exact layer naming system should follow your project's CAD standards.

Why Use Separate Layers?

It allows you to:

Turn hatches on or off.
Change hatch display.
Control plotting.
Manage complex drawings.
Keep the drawing organized.

Hatch in a Section Drawing

Hatch is commonly used in sectional drawings to indicate areas that have been cut.

For example, a building section might use different graphical patterns for different construction materials.

However, the correct representation depends on the applicable drafting standard and project requirements.

Basic Workflow

Draw the section geometry.
Ensure the material boundary is closed.
Start Hatch.
Select the enclosed material region.
Choose the required pattern.
Adjust scale and angle.
Review the drawing.
Plot a test PDF if necessary.

Hatch vs Solid Fill

Both can fill an area, but they serve different visual purposes.

Feature	Hatch Pattern	Solid Fill
Appearance	Patterned	Completely filled
Best for	Material/section indication	Highlighting or simple fills
Pattern scale	Adjustable	Not applicable
Pattern angle	Usually adjustable	Not applicable
Small areas	May become crowded	Often easier to read

Choose the method that provides the clearest drawing according to your project standards.

Best Practices for Using Hatch

For professional and readable drawings:

Use closed boundaries whenever possible.
Use meaningful hatch patterns.
Keep hatch scale appropriate for the drawing.
Avoid unnecessarily dense patterns.
Put hatches on appropriate layers.
Check hatch visibility before plotting.
Use transparency only when it improves readability.
Follow applicable drawing standards.
Review the hatch after modifying boundaries.
Keep the drawing organized.
