Understanding Arrays in AutoCAD
Using arrays in AutoCAD is a powerful method for duplicating objects in specific patterns. This guide focuses on how to create a circular array, along with additional information about other types of arrays.
Steps to Create a Circular Array in AutoCAD
Initiate the Polar Array Command: Begin by navigating to the Home tab, and locate the Modify panel. Click on the Polar Array option to initiate the circular array function.
Select the Objects for Duplication: Click on the objects you wish to include in your circular array. This could be any shape or drawing element you have created.
Specify the Center Point: After selecting the desired objects, choose a center point around which the array will be formed. This point is crucial as it determines the rotation axis for your array.
Set the Number of Items: Enter the number of duplicate items you want in the array by typing ‘i’ for Items and inputting the total count. The software will display a preview of how the array will appear.
- Determine the Fill Angle: Define the angle to be covered by your array. Type ‘a’ for Angle and enter the degree measurement. You can also adjust the arc through the use of the arrow grips available in the preview.
Creating Other Types of Arrays in AutoCAD
Rectangular Arrays
Access the Rectangular Array Tool: With nothing selected, go to the Home tab and select the Rectangular Array option from the Modify panel.
Choose Your Objects: Select the object(s) you want to arrange into a rectangular format and press Enter.
- Adjust Parameters: Utilize the grips in the array preview to modify the spacing, as well as the number of rows and columns, or adjust these values directly from the Array context ribbon.
Path Arrays
Select the Path Command: Initiate the Path Array command from the Modify panel.
Determine the Path: Specify a path on which your arrayed objects will be placed. This could be a line, curve, or polyline.
- Select Objects to Array: Choose the object(s) to be repeated along the defined path and adjust orientation and spacing as needed.
Frequently Asked Questions
What is the difference between Polar and Rectangular Arrays in AutoCAD?
Polar arrays duplicate objects in a circular pattern around a specified center point, making them ideal for circular layouts. Rectangular arrays create duplicates in rows and columns, suited for grid-like patterns.
Can I edit arrays after creating them?
Yes, one of the advantages of using arrays in AutoCAD is that they are associative. This means you can modify the parameters or the components of an existing array, and the changes will automatically apply to all copies.
Is there a command to repeat the last used array operation?
To quickly repeat the last used command in AutoCAD, you can simply press the F2 key, or use the keyboard shortcut Ctrl + J to seamlessly execute previous commands without reentering them.
