How To Send Hatch Back In AutoCAD?

Understanding Hatch Disappearance in AutoCAD

When working with hatch patterns in AutoCAD, it’s common to encounter issues where your hatch seems to disappear. One significant reason for this is the setting of the system variable HPMAXLINES. If this variable is set too low, it limits the maximum number of lines in the hatch, potentially causing the pattern to vanish. Another reason could be related to the hatch pattern that is being utilized; if it’s not a SOLID pattern, the chosen scale might make the pattern too sparse to be visible within the hatch’s boundary.

Steps to Restore a Hatch Boundary

To bring back a hatch boundary that may have gone missing, follow these steps:

1. Type HATCHEDIT into the command line.
2. Select the hatch you wish to edit from your drawing.
3. When the Hatch Edit dialog box appears, click on Recreate Boundary.
4. At the prompt “Enter type boundary object,” you can input P for polyline or R for region, based on your requirement.
5. Decide whether you want to associate the hatch with the newly created boundary as prompted.

Fixing Hatch Issues in AutoCAD

If your hatch is not displaying correctly, consider these troubleshooting steps:

1. Ensure that the layer containing the hatch is active and not frozen.
2. Navigate to Options/Display, and confirm that the “apply solid fill” option is selected. After making changes, click Apply and then OK.
3. Enable the hatch quick preview and fill mode for better visibility.

Removing Hatch from Objects

If you need to un-hatch an area, follow these instructions:

1. Select the hatch object directly. The Hatch Editor contextual tab will open on the Ribbon.
2. From the editor, you can make any adjustments needed; changes will be visible in real-time.
3. Once satisfied with your adjustments, click Close Hatch Editor to save the changes.

Creating a New Hatch Boundary

To generate a hatch boundary efficiently:

1. Select the existing hatch that requires a new boundary.
2. Right-click on the selected hatch, and choose Generate Boundary from the context menu. This will display grips for any created polylines.

Displaying Hatch Boundaries in AutoCAD

If you want to see hatch boundaries in your drawing, you can do the following:

1. Select the objects that comprise your boundary. You can then perform grip editing on these objects.
2. Alternatively, on the Hatch edit ribbon, you can click on Show Boundary objects. If you find grips are not displayed, ensure that the annotative property is unchecked before retrying.

FAQ

What causes hatches to disappear in AutoCAD?

Hatches may disappear due to a low HPMAXLINES setting or if the hatch pattern is not compatible with the scale, rendering it too sparse to see.

How can I troubleshoot hatch visibility issues?

Check if the hatch layer is active, ensure solid fill is enabled in the options, and turn on the hatch preview and fill mode.

What steps should I take to completely remove a hatch object?

To remove a hatch, double-click on it to open the Hatch Editor, choose Pick Points, and use the ‘S’ command to select internal areas to erase the hatch.
