Editing a Hatch Pattern
You can change a hatch pattern by selecting an object and changing the pattern listed on the Brush page of its Properties window (see Properties Window).
If you want to edit a hatch pattern, you will first have to explode it (see Exploding Objects). For associative hatches, you must first explode the object into its boundary and hatch components.
