Welcome to this tutorial on how to add a Lisp in AutoCAD!

What is a Lisp in AutoCAD?

A Lisp is a programming language that allows you to create custom commands and automate repetitive tasks in AutoCAD. It stands for “LISt Processing” and was developed back in the 1950s. Lisp functions can be written and saved in .lsp files, which can then be loaded into AutoCAD.

Adding a Lisp in AutoCAD

Now, let’s dive into the steps involved in adding a Lisp in AutoCAD:

  1. Create a Lisp file: To add a Lisp, you first need to create a .lsp file. You can do this using any text editor such as Notepad or Notepad++. Make sure to save the file with the .lsp extension.
  2. Write your Lisp code: Open the .lsp file and start writing your custom Lisp code. This code will define the functionality of your custom command or automation task.

    For example, you can write code to draw specific shapes, modify existing objects, or perform calculations.

  3. Save the Lisp file: Once you have finished writing your Lisp code, save the .
  4. Load the Lisp file in AutoCAD: In AutoCAD, type “Appload” in the command line or go to “Tools > Load Application” from the menu bar. This will open the “Load/Unload Applications” dialog box.
  5. Browse and select your .lsp file: In the “Load/Unload Applications” dialog box, click on the “Browse..” button and navigate to the location where you saved your . Select the file and click “Load”.
  6. Run the Lisp command: After loading the Lisp file, you can now run the custom command or automation task by typing its name in the AutoCAD command line. The command will execute according to the code you wrote in your Lisp file.

Benefits of Using Lisp in AutoCAD

Using Lisp in AutoCAD offers several benefits:

  • Automation: Lisp allows you to automate repetitive tasks, saving you time and effort.
  • Customization: With Lisp, you can create custom commands tailored to your specific needs and workflow.
  • Productivity: By automating tasks and creating custom commands, you can increase your productivity and efficiency in AutoCAD.
  • Flexibility: Lisp provides a flexible programming environment, allowing you to extend AutoCAD’s capabilities beyond its built-in features.
  • Community Support: There is a vast community of Lisp users and developers who share their knowledge and provide support for creating and using Lisp routines in AutoCAD.

In conclusion,

Lisp is a powerful programming language that can enhance your experience with AutoCAD by adding custom commands and automating repetitive tasks. By following the steps outlined in this tutorial, you can easily add a Lisp in AutoCAD and take advantage of its benefits. So why not give it a try?

Happy coding!
