Can You Use Lisp in AutoCAD LT?

Can You Use Lisp in AutoCAD LT?

AutoCAD LT is a popular software used by professionals in the architecture, engineering, and design industries. It offers a range of powerful tools and features to create precise 2D drawings. One feature that many AutoCAD users greatly appreciate is the ability to customize the software using Lisp programming.

What is Lisp?

Lisp, which stands for ‘LISt Processing,’ is a programming language that was developed in the late 1950s. It is known for its simplicity and flexibility, making it an ideal choice for creating custom functions and automating repetitive tasks in AutoCAD.

However, when it comes to AutoCAD LT, there are some limitations to keep in mind.

AutoCAD LT’s Limitations

AutoCAD LT is a more affordable version of AutoCAD but with some reduced functionality. While it still provides an extensive set of tools for 2D drafting, there are certain features that are not available in AutoCAD LT, including the ability to use Lisp programming directly.

So, can you use Lisp in AutoCAD LT?

The short answer is no. Unlike the full version of AutoCAD, AutoCAD LT does not support customizations made with Lisp programming. This limitation can be disappointing for those who rely heavily on Lisp routines to enhance their productivity and automate repetitive tasks.

Alternative Options

  • VBA: If you still want to automate tasks and create custom functions within AutoCAD LT, you can use Visual Basic for Applications (VBA). VBA allows you to create macros and automate repetitive processes using a similar syntax as other Microsoft Office applications.
  • AutoLISP to VBA Conversion: If you have existing Lisp routines that you want to use in AutoCAD LT, you can convert them to VBA code using specialized conversion tools.

    This way, you can still benefit from the automation capabilities of your existing Lisp programs.

  • Custom Commands: While you cannot directly use Lisp in AutoCAD LT, you can create custom commands using the built-in customization features of the software. These commands can be assigned to keyboard shortcuts or toolbar buttons, allowing you to access frequently used tools and functions more efficiently.


Although AutoCAD LT does not support Lisp programming directly, there are alternative options available. You can explore using VBA for creating macros and automating tasks within AutoCAD LT. Additionally, converting existing Lisp routines to VBA code or creating custom commands can help enhance your productivity and streamline your workflow.

While it may not offer the same level of flexibility as the full version of AutoCAD, AutoCAD LT remains a powerful tool for 2D drafting and design. By leveraging its built-in customization features and exploring alternative options like VBA, you can still achieve efficient workflows and accomplish your design goals.

Remember to always check the official documentation and resources provided by Autodesk for up-to-date information on supported features and customization options in AutoCAD LT.
