How Do You Use Commands in AutoCAD?

AutoCAD is a powerful software used by professionals in various industries to create precise and detailed drawings. One of the key features of AutoCAD is its command-line interface, which allows users to execute commands and perform various tasks efficiently. In this article, we will explore how to use commands in AutoCAD effectively.

Accessing the Command Line

To access the command line in AutoCAD, you can simply press the Ctrl key and the Spacebar simultaneously. Alternatively, you can click on the command line located at the bottom of the screen. Once you have accessed the command line, you can start inputting commands to execute specific actions.

Basic Commands

In AutoCAD, there are numerous commands available that cater to different needs and tasks. Here are some essential commands to get you started:

  • Line: This command enables you to draw straight lines between two points. Simply type “line” in the command line and press Enter. Then, specify the start and end points of the line by clicking on the desired locations.
  • Circle: With this command, you can create circles of various sizes. Type “circle” in the command line and press Enter.

    Then, specify the center point of the circle followed by its radius or diameter.

  • Arc: The arc command allows you to draw arcs in your drawings. To use this command, type “arc” in the command line and press Enter. Then, specify three points – start point, endpoint, and a point on the arc – or define other properties such as radius or length.
  • Mirror: This handy command lets you create mirror images of objects. Type “mirror” in the command line and press Enter. Then, select the objects you want to mirror, specify a line as the mirror axis, and AutoCAD will create a mirrored copy of the selected objects.

Advanced Commands

AutoCAD also offers advanced commands that can greatly enhance your productivity and efficiency. Here are a few examples:

  • Offset: The offset command is used to create parallel lines or concentric circles at a specified distance from existing objects. To use this command, type “offset” in the command line and press Enter. Then, select the object you want to offset, specify the distance, and AutoCAD will generate the offset geometry.
  • Trim: With this command, you can remove unwanted parts of lines or other objects that intersect with a cutting edge. Type “trim” in the command line and press Enter.

    Then, select the cutting edges followed by the objects you want to trim.

  • Array: The array command allows you to create multiple copies of objects in various patterns. To use this command, type “array” in the command line and press Enter. Then, select the objects you want to array, specify the number of rows and columns, and AutoCAD will generate an array based on your settings.

Customizing Commands

In addition to using built-in commands, AutoCAD allows users to customize commands according to their specific needs. You can redefine existing commands or create new commands using AutoLISP or Visual LISP programming languages.

Redefining Commands

To redefine an existing command in AutoCAD:

  1. Open the AutoCAD menu and go to the “Customize” tab.
  2. Select “Edit Aliases” to open the ACAD.PGP file.
  3. Locate the command you want to redefine and modify its alias or command string.
  4. Save the changes and close the file.

Creating Custom Commands

To create a custom command in AutoCAD:

  1. Open the AutoCAD menu and go to the “Customize” tab.
  2. Add a new line at the end of the file, specifying your desired alias and the corresponding command string for your custom command.

In conclusion, commands are an essential part of using AutoCAD effectively. By mastering various commands, you can streamline your workflow, create complex drawings with ease, and customize AutoCAD to suit your specific requirements.
