How to Make Script AutoCAD?

Understanding AutoCAD Script Files

An AutoCAD script file, which has an .scr extension, is a plain text document containing a sequence of AutoCAD commands. Each line represents a command that the software can execute in the Command prompt, allowing users to automate repetitive tasks efficiently.

Creating a Script File in AutoCAD

1. Open a Text Editor: Use a text editor such as Notepad or any code editor of your choice.

2. Write Commands: Enter the AutoCAD commands you wish to automate, each on a new line.

3. Save the File: Save the document with an .scr extension, for example, myscript.scr.

4. Test Your Script: It’s advisable to test the commands individually in AutoCAD before running the script to ensure they perform as expected.

Importing an SCR File into AutoCAD

1. Download the SCR file: If you have a script file provided by someone, download it to your local machine.

2. Edit the File: Open the file in a text editor and, if necessary, append any required coordinates or commands at the beginning.

3. Save Changes: After editing, save and close the file.

4. Open AutoCAD: Launch AutoCAD and load the drawing in which you want to use the script.

5. Run the Script: Drag and drop the SCR file into the AutoCAD model view to execute the script.

Running a Script in AutoCAD 2025

1. Access Terminal: Click on your operating system’s terminal or command prompt.

2. Enter Command: For running a script, input the following command:

   • For standard AutoCAD: AutoCAD drawing_name -b script_name
   • For AutoCAD LT: AutoCAD LT drawing_name -b script_name
3. Press Enter: Hit Enter to execute the command. The specified drawing will open, and the commands in the script will run automatically.

Utilizing AutoLISP for Automation

AutoLISP, a derivative of the LISP programming language, allows users to write custom commands and streamline processes in AutoCAD. Using AutoLISP scripts can make complex tasks easier and more efficient.

Running Scripts in Different Workspaces

For users operating in specific workspaces, such as the Drafting & Annotation workspace:

1. Navigate to the Manage tab.
2. Select Applications from the dropdown menu.
3. Click on Run Script to execute your desired script.

Macros in AutoCAD LT

While AutoCAD LT does not support AutoLISP, users can still create macros. These macros can be defined by modifying the Macro property of a command, accessible via the Customize User Interface Editor in Windows or the Customize dialog in macOS.

Learning AutoLISP Programming

Learning AutoLISP can enhance your skills in AutoCAD, enabling the development of custom automation that can save time and boost productivity. Resources, including tutorials and videos, are widely available online to help beginners get started.

Obtaining XY Coordinates

To retrieve XY coordinates in AutoCAD:

1. Look for the Utilities panel on the Home tab.
2. Select ID Point and click on the desired location on your drawing.
3. The coordinate values will appear in the Command prompt.

Inserting XY Coordinates

Adding coordinates directly into AutoCAD can be done by:

1. Accessing the Geolocation tab.
2. Selecting Edit Location from the panel and following the prompts to input your coordinate system.
3. Pressing ENTER repeatedly to finalize the input.

Command Line Access

Revealing the command line in AutoCAD is simple. Use the keyboard shortcut CTRL + 9 for Windows or CMD + 3 on macOS to toggle its visibility.

FAQs

1. Can I use complex commands in an AutoCAD script?
Yes, you can include complex commands and sequences in your script file to automate intricate tasks.

2. Is knowledge of programming required to use AutoCAD scripts?
While knowing programming helps, it is not mandatory for using scripts. Basic familiarity with AutoCAD commands suffices for creating simple scripts.

3. Can AutoCAD scripts be shared with others?
Absolutely. You can share .scr files with colleagues, enabling them to use the same automation you’ve created in their own AutoCAD projects.
