How Do You Unlock Hatch in AutoCAD?

To unlock a hatch in AutoCAD, you need to unblock it at the file level if it is a blocked hatch pattern. Here's how:

1. Right-click on the hatch pattern file (usually a .pat file).
2. Choose Properties from the context menu.
3. In the Properties dialog box, locate the Unblock option.
4. Click Unblock, if available, or ensure it's not blocked.
5. Click OK to save the changes.

This process ensures that the hatch pattern is accessible and can be used within AutoCAD. Note that this process refers to unblocking the file containing the hatch pattern, not unlocking a hatch object that's already in a drawing. There isn't a direct "lock/unlock" feature for hatch objects within the AutoCAD interface. You can, however, prevent editing of existing hatch objects by putting them on a locked layer.
