Polar Array

It is also called as a circular array. The polar array is defined as the arrangement of copies of an object in a circular form.

Let's consider an example to draw small circles around a big circle.

The steps to create a polar array are given below:

The steps to create a polar array are given below:

1. Open the AutoCAD software

2. Click on the Circle icon on the Ribbon Panel, as shown in the below image:

We can also write Circle or C on the command line and Press Enter.

3. Specify the center point on the workspace or drawing area to draw a small circle.

4. Specify the diameter for a first circle (example- 1) and Press Enter.

5. Now, again select the Circle icon or type C on the command line and specify a center point for a big circle near the small circle.

6. Specify the diameter for the big circle (example- 5) and Press Enter.

The circles here will appear as the below image:

We can determine any value of diameter according to the requirements.

7. Select the Polar Array from the drop-down list of the rectangular array on the ribbon panel.

The polar array icon will look like the given image:

8. Select the object(small circle) with the small square cursor and Press Enter, as shown in the below image:

9. Now, specify the center to create the array. Here, we can specify the center of the big circle.

We can also specify the center of any object according to the requirements.

10. The default polar array will be created, as shown in the below image:

We can also type AR -> select the small object with the square cursor- > select Polar - > select the center axis -> and then Press Enter on the command line.

Note: We need to maintain the distance between the center axis and the object to be copied. The polar array will consider the same distance for all the copied objects by default. The greater the gap between the center of axis and object, the objects will be copied circularly at the same distance from the axis.

Elements Modification

To modify elements, follow the below steps:

11. Go to the top row of the screen, which will look like the below image:

We can modify the value according to the requirements.

1. Let's modify it using the values:

Items= 8
Rows= 2
Between under Items= Adjusts automatically according to the number of items.
Between under rows= 4
Fill under Items= 270

The figure will now look like the given image:

2. Press Esc or Enter or Spacebar to exit.

The blue arrow and the square are used to rotate the copied objects and manage the distance from the center.
