AutoCAD is a powerful design and drafting software widely used by architects, engineers, and designers. One of the most useful features in AutoCAD is the "ARRAY" command, which allows users to create multiple copies of objects arranged in a pattern. Whether you need to arrange items in a rectangular grid, circular pattern, or along a path, the ARRAY command offers flexibility and efficiency.

In this detailed guide, we will walk you through the different ways to use the ARRAY command in AutoCAD, from basic functions to advanced techniques, helping you master this tool and improve your workflow.

1. What is the ARRAY Command?

The ARRAY command in AutoCAD allows you to duplicate objects in a defined pattern. This pattern can be rectangular (grid), circular (polar), or along a specified path. Instead of manually creating multiple copies of the same object, the ARRAY command automates the process and ensures that your copies are evenly spaced and arranged in the desired formation.

For example, you can use the ARRAY command to:

  • Duplicate a chair design multiple times across a floor plan.
  • Create a series of light fixtures arranged in a circular pattern around a central point.
  • Distribute windows evenly along a building façade.

The ARRAY command can be accessed in several ways, and it comes with various options for fine-tuning the layout of your objects.

2. Types of Arrays in AutoCAD

AutoCAD offers three primary types of arrays:

  1. Rectangular Array: Creates rows and columns of objects at specified distances.
  2. Polar Array: Arranges objects in a circular pattern around a central point.
  3. Path Array: Distributes objects along a defined path (e.g., line, arc, or polyline).

Each type has its unique set of features and uses, and in the following sections, we will explain how to use each one.

3. How to Access the ARRAY Command

There are multiple ways to access the ARRAY command in AutoCAD:

  • Command Line: Type ARRAY and press Enter.
  • Ribbon: Go to the Home tab, click the Array tool in the Modify panel.
  • Right-click Menu: After selecting an object, right-click and choose Array from the context menu.

Once accessed, you will be prompted to select the type of array you want to create: Rectangular, Polar, or Path.

4. Step-by-Step Instructions for Using the ARRAY Command

A. Rectangular Array

A rectangular array creates rows and columns of objects with a specified number of copies, row spacing, and column spacing. Here’s how to create a rectangular array:

  1. Start the ARRAY Command: Type ARRAY in the command line or click the Array tool from the Ribbon.
  2. Select the Object to Array: Click to select the object you want to copy.
  3. Specify the Array Type: Type R for Rectangular Array and press Enter.
  4. Specify the Number of Rows and Columns:
    • Rows: Enter the number of rows (the number of copies in the vertical direction).
    • Columns: Enter the number of columns (the number of copies in the horizontal direction).
  5. Set the Spacing:
    • Specify the distance between rows and columns by either typing the value or clicking to define it on the screen.
  6. Preview and Confirm: A preview of your array will be shown. Adjust the spacing and number of copies if necessary. Press Enter to create the array.

Tip: You can edit the array after creation by selecting it and using the grips to modify the number of rows, columns, or spacing.

B. Polar Array

A polar array arranges objects in a circular pattern around a central point. Here’s how to use it:

  1. Start the ARRAY Command: Type ARRAY or click the Array tool.
  2. Select the Object to Array: Choose the object you want to copy.
  3. Specify the Array Type: Type P for Polar Array and press Enter.
  4. Define the Center Point: Click the point around which the array will be formed (usually the center of your circular pattern).
  5. Set the Number of Items: Enter the number of copies you want to create in the circular pattern.
  6. Specify the Angle: Define the total angle of the array (for example, 360 degrees for a full circle).
  7. Preview and Confirm: A preview will show the objects arranged in a circle. Adjust the parameters if necessary, and press Enter to confirm.

Tip: You can also modify the angle between objects, as well as the total number of objects in the polar array, by editing the array after it’s created.

C. Path Array

A path array allows you to distribute objects along a predefined path, such as a line, arc, or polyline. Here’s how to use it:

  1. Start the ARRAY Command: Type ARRAY or click the Array tool.
  2. Select the Object to Array: Click the object you want to replicate.
  3. Specify the Array Type: Type A for Path Array and press Enter.
  4. Select the Path: Choose the path (line, arc, or polyline) along which the objects will be arranged.
  5. Specify the Number of Copies: Enter the number of objects you want to distribute along the path.
  6. Preview and Adjust: A preview will show the objects placed along the path. You can adjust the spacing and the number of items, then press Enter to finalize the array.

Tip: You can use grips to adjust the placement of the objects along the path after creating the array.

5. Tips and Tricks for Using the ARRAY Command

  • Use the Array Preview: Always check the array preview before confirming your selection. It ensures the objects are arranged exactly as you intended.
  • Use the Align and Distribute Options: After creating an array, you can use AutoCAD's Align and Distribute options to further tweak the positioning of arrayed objects.
  • Dynamic Arrays: Use dynamic input (if enabled) to quickly modify array properties on the fly.
  • Copy vs. Array: Use an array when you need multiple objects with equal spacing and positioning, but opt for copying individual objects if the placement is more irregular.

6. Editing and Modifying Arrays

Once an array is created, it’s easy to modify:

  1. Select the Array: Click on the array to select it.
  2. Edit Using Grips: Grips appear on the array, which you can drag to modify the number of items, spacing, or overall arrangement.
  3. Change Array Properties: Use the Array Properties button in the Ribbon or right-click the array to access options like adjusting the row and column counts or the angle in a polar array.

7. Common Issues and Troubleshooting

  • Array Not Showing: If the array doesn’t appear after creation, ensure your zoom settings are appropriate or check for visibility settings that may hide certain objects.
  • Spacing Issues: If objects in your array appear too close or too far apart, check the spacing values in the array properties and adjust them accordingly.
  • Object Clipping: Objects in an array might get clipped if they are placed too close to the edges of the drawing area. Adjust the layout or zoom out.

8. Conclusion

Mastering the ARRAY command in AutoCAD can significantly speed up your design process. Whether you’re working with simple rectangular arrays or more complex polar and path arrays, this tool allows you to create and modify object patterns with ease and precision.

By following the steps and tips in this guide, you can confidently use the ARRAY command to enhance your workflow and create professional designs. Experiment with the different array types and explore the advanced editing options to tailor your arrays to suit your specific project needs.
