What Is Polar Array in AutoCAD?

In AutoCAD, the Polar Array command is a powerful tool that allows you to create multiple copies of objects arranged in a circular pattern. It is particularly useful for creating symmetrical designs, such as radial patterns or circular arrays of objects. The Polar Array command helps save time and effort by automating the process of creating repetitive elements.

How to Use the Polar Array Command

To use the Polar Array command in AutoCAD, follow these simple steps:

Step 1: Select the Object

Select the object or objects you want to create an array of. This can be done by clicking on the object using the selection tool.

Step 2: Activate the Polar Array Command

To activate the Polar Array command, there are several ways:

  • You can type “ARRAYPOLAR” into the command line.
  • You can access it from the menu by going to Modify > Polar Array.
  • You can use the keyboard shortcut by pressing “PA” followed by “Enter”.

Step 3: Set Center Point and Number of Items

After activating the command, AutoCAD will prompt you to specify a center point for your array. You can either pick a point on your drawing or enter specific coordinates.

Next, you will be prompted to enter the number of items you want in your array. You can specify any whole number greater than zero.

Step 4: Specify Angle Range

AutoCAD will then prompt you to specify an angle range for your array. You have two options:

  • Angle: You can enter a specific angle in degrees.

    This will determine the total angle spanned by the array.

  • Fill Angle: You can enter a specific fill angle in degrees. This will determine the angle between each item in the array.

Step 5: Customize Options (Optional)

AutoCAD also provides additional options to further customize your array:

  • Rotate Items: You can choose to rotate the items in your array by a specified angle.
  • Associative: You can make your array associative, which means that if you modify one item, all other items in the array will be updated accordingly.

Step 6: Complete the Array

Once you have specified all the necessary parameters and customized options, press “Enter” or right-click to complete the Polar Array command. AutoCAD will create the array based on your inputs and display it on your drawing.

Tips for Using Polar Array Effectively

To get the most out of the Polar Array command, here are some tips:

  • Experiment with Different Angles: Try different angle values to create various patterns and arrangements. You can achieve symmetrical designs by using multiples of 360 degrees.
  • Combine with Other Commands: The Polar Array command can be combined with other commands like Copy, Scale, or Rotate to create even more complex arrays and designs.
  • Create Associative Arrays: Making your arrays associative allows for easier editing and modification later on. If you need to change any element, you won’t have to recreate the entire array.

By mastering the use of the Polar Array command in AutoCAD, you can efficiently create repetitive patterns and elements in your drawings. This powerful tool will save you time and effort while enhancing your design capabilities.
