Using Hatch Patterns in AutoCAD

AutoCAD supplies a solid fill and more than 50 industry-standard hatch patterns that you can use to differentiate the components of objects or represent object materials. AutoCAD supplies 14 hatch patterns that conform to the ISO (International Standardization Organization) standards. When you select an ISO pattern, you can specify a pen width, which determines the lineweight in the pattern.
You can use a pattern supplied with AutoCAD or one from an external pattern library.

You can also define your own hatch pattern using the current linetype with the User Defined Pattern option, or you can create more complex hatch patterns. For information about creating hatch patterns, see chapter 2, “Linetypes and Hatch Patterns,” in the Customization Guide. To reduce file size, a hatch pattern is defined in the drawing database as a single graphical object.
In the first procedure that follows, you use the Hatch Pattern Palette dialog box to choose an ISO pattern. In the second procedure, you create a simple line pattern by defining the spacing between the lines and creating a second set of lines at 90 degrees to the original lines.

To use an ISO hatch pattern

  1. From the Draw menu, choose Hatch.
  2. In the Boundary Hatch dialog box, choose the Quick tab.
  3. Under Type, choose Predefined.
  4. Under Pattern, choose an ISO pattern name from the list, or if you prefer to choose the pattern by viewing preview images, choose the […] button next to the Pattern list.
  5. In the Hatch Pattern Palette dialog box, choose the ISO tab.
  6. Choose a pattern and choose OK.
  7. In the Boundary Hatch dialog box, choose Pick Points.
  8. Specify an internal point and press ENTER.
  9. To preview the hatch, right-click and choose Preview.
  10. If the pattern is not displayed the way you want, you may need to adjust the pattern, scale, or angle. Use the Preview button in the Boundary Hatch dialog box to preview the hatch with the new settings.
  11. Press ENTER to return to the Boundary Hatch dialog box. Choose OK to apply the hatch.
