by

Changing system variables in AutoCAD is an essential task that allows users to customize the software according to their specific needs. System variables are predefined settings that control various aspects of AutoCAD’s functionality, such as display settings, drawing units, and command behavior. In this tutorial, we will explore how to change system variables in AutoCAD effectively.

Accessing the System Variables

Before we delve into the process of changing system variables, let’s first understand how to access them. To access the system variables in AutoCAD, follow these steps:

  • Step 1: Open AutoCAD on your computer.
  • Step 2: In the command line or dynamic input area at the bottom of the screen, type “CUI” and press Enter.

    This will open the Customize User Interface window.

  • Step 3: In the Customize User Interface window, click on the “Transfer tab“.
  • Step 4: From the Panels list on the left side of the window, expand “Main Customization Files“.
  • Step 5: Expand “CUI File Types” and select “Main Menu“. This will display all available menus.
  • Step 6: Select “All commands” from the list of menus displayed on the right side of the window.
  • Step 7: In the Search box at the top right corner of the window, type “_sysvars” and press Enter. This will filter out only system variables.
  • Step 8: You will now see a list of all the system variables in AutoCAD.

Changing System Variables

Now that we know how to access the system variables, let’s learn how to change them. Follow these steps:

Method 1: Using the Command Line

This method allows you to change system variables directly using the command line. Here’s how:

  • Step 1: In the command line, type “VARIABLES” and press Enter. This will open the System Variables dialog box.
  • Step 2: In the System Variables dialog box, locate the variable you want to change.
  • Step 3: Double-click on the value of the variable or select it and click on the “Edit Value” button.
  • Step 4: Modify the value of the variable according to your requirements.
  • Step 5: Click on “OK” to save your changes and close the System Variables dialog box.

Method 2: Using the Options Dialog Box

This method allows you to change system variables through AutoCAD’s options. Here’s how:

  • Step 1: Click on the “A” icon at the top left corner of AutoCAD’s interface.

    This will open a drop-down menu.

  • Step 2: From the drop-down menu, select “Options“. This will open the Options dialog box.
  • Step 3: In the Options dialog box, click on the “System” tab located on the left side of the window.
  • Step 4: In the System tab, click on the “Variables” button.
  • Step 5: In the System Variables dialog box, locate the variable you want to change.
  • Step 6: Double-click on the value of the variable or select it and click on the “Edit Value” button.
  • Step 7: Modify the value of the variable according to your requirements.
  • Step 8: Click on “OK” to save your changes and close both the System Variables and Options dialog boxes.

Tips for Changing System Variables

To ensure a smooth experience when changing system variables in AutoCAD, consider these tips:

  • TIP #1: Be cautious while modifying system variables as incorrect values may cause unexpected behavior in AutoCAD.
  • TIP #2: Make note of original variable values before making any changes. This will help you revert back if needed.
  • TIP #3: Consult AutoCAD’s documentation or online resources to understand each system variable and its purpose before modification.

Congratulations! You have successfully learned how to change system variables in AutoCAD using two different methods.

By customizing these variables, you can enhance your AutoCAD experience and tailor it to your specific requirements. Remember to exercise caution while modifying system variables and always make note of original values for easy reversion.
