What Are the Different Types of Hatch in AutoCAD?

AutoCAD is a powerful software widely used in the field of computer-aided design and drafting. It offers a wide range of tools and features that help architects, engineers, and designers create accurate and detailed drawings.

One important feature in AutoCAD is the hatch command, which allows users to fill enclosed areas with patterns or solid colors. In this article, we will explore the different types of hatch available in AutoCAD and how to use them effectively.

1. Solid Hatch:

The solid hatch is the simplest type of hatch available in AutoCAD.

It fills the selected area with a solid color or pattern. To create a solid hatch, you need to specify the boundaries of the area you want to fill and then choose a color or pattern from the available options. Solid hatches are commonly used to represent solid materials like concrete or brickwork.

2. Gradient Hatch:

A gradient hatch is a type of hatch that creates a smooth transition between two colors or shades.

It is often used to represent materials that have a gradual change in color or density, such as painted surfaces or natural landscapes. To create a gradient hatch, you need to specify two colors and the angle at which the gradient should be applied.

3. Pattern Hatch:

Pattern hatches are used to fill an area with repeating patterns, such as tiles or bricks.

AutoCAD offers a variety of pre-defined patterns that can be applied to create pattern hatches. These patterns can be scaled and rotated according to your requirements.

3.1 Custom Pattern Hatch:

In addition to the pre-defined patterns, AutoCAD also allows you to create custom pattern hatches using lines, circles, arcs, and other basic shapes. This gives you more flexibility in creating unique and intricate patterns for your designs.

4. Associative Hatch:

Associative hatches are dynamic hatches that are linked to the boundaries of the area they fill.

If the boundaries of the area are modified, the hatch automatically adjusts itself to fit the new shape. This feature is particularly useful when working with complex designs that require frequent modifications.

5. Hatch Boundary:

To create a hatch in AutoCAD, you need to specify a boundary for the area you want to fill.

The boundary can be a closed polyline, a circle, an ellipse, or any other closed shape. AutoCAD provides various tools for creating and modifying boundaries, such as the polyline tool and the circle tool.

5.1 Island Detection:

AutoCAD also offers an island detection feature that automatically identifies islands or enclosed areas within a boundary and creates separate hatches for them. This is especially helpful when working with complex drawings that contain multiple enclosed areas.

  • Note: It is important to ensure that your hatch boundaries are closed and do not intersect each other. Open or intersecting boundaries may result in unexpected hatch patterns or errors.


Understanding the different types of hatch available in AutoCAD is essential for creating accurate and visually appealing drawings. Whether you need to represent solid materials, gradients, patterns, or associative hatches, AutoCAD provides a wide range of options to suit your design requirements.

By using these different types of hatch effectively, you can enhance your drawings and convey your design intent more effectively.
