How to Reverse Array Direction in AutoCAD?

To reverse the direction of an array in AutoCAD, follow these detailed steps:

Understanding Array Directions

An array in AutoCAD allows you to create multiple copies of objects in a specified direction. It is essential to grasp how to manipulate these arrays effectively, including reversing their directions.

Steps to Change Array Direction in AutoCAD

1. Select the Array
   Begin by clicking on the array you wish to modify. The selected array will display its grips, which are small blue squares at the corners and midpoint.

2. Identify the Direction Arrow
   Look closely at the array, and you will notice direction arrows. These arrows indicate the current direction of the array. Clicking on one of these arrows will allow you to change the orientation.

3. Modify the Direction
   Click and drag the arrow to switch the direction of the array. Moving the arrow will reposition the elements along the new path. You can also input specific angles or use reference points for precise control.

4. Use Properties Palette for Detailed Adjustments

   • With the array selected, navigate to the Properties palette (accessible via the Home tab).
   • There, you can adjust properties such as spacing, number of rows or columns, and the method of the array. This feature provides additional control over your array layout.
5. Confirm Changes
   Once you are satisfied with the new direction, you can confirm your changes by clicking outside the array. If the arrangement looks correct, you’re done. If not, you can repeat the above steps.

Reversing the Array Direction Using Commands

For users who prefer command inputs, follow these steps:

1. Select the Command
   Type ARRAY in the command line and press Enter. This will initiate the array command.

2. Select Objects
   Choose the objects you wish to include in your array. Press Enter to finalize your selection.

3. Specify the Array Type
   Choose between a rectilinear array or a path array. For reversing direction, the rectilinear array is often used.

4. Input the Necessary Parameters
   Enter values for the number of rows, columns, and spacing. When specifying direction, you can reverse the order by inputting negative values for distance or changing the array’s direction via grips.

5. Finalize the Array
   Press Enter to create your array with the specified properties.

Additional Techniques for Advanced Users

• Editing Existing Arrays: If you have an existing array, you can use the Properties option or the Edit Array function to modify its direction.
• Using the OTRACK Tool: The Object Tracking (OTRACK) tool can help in aligning your objects as you drag the direction arrow to ensure precise placements along paths.

Frequently Asked Questions (FAQ)

1. How do I erase items from an array in AutoCAD?
   To erase items from an array, select the array, hold down the Ctrl key, and click on the items you wish to delete. Then press the Delete key to remove them.

2. What are the different types of arrays in AutoCAD?
   AutoCAD offers rectangular, polar, and path arrays, enabling various arrangements of copied objects depending on project requirements.

3. Can I reverse an array without using the grips?
   Yes, you can reverse an array by using command inputs. Use the ARRAY command and adjust the parameters as needed without manually dragging the grips.
