AutoCAD LT 2024 – AutoLISP

SHARE

One of the differences between AutoCAD and AutoCAD LT was the ability to automate functionality by programming. While AutoCAD has the ability to use both VB.NET,C# and AutoLISP AutoCAD LT did not have that luxury until now.

With AutoCAD LT 2024, Autodesk has given us the capability to automate tasks with the use of AutoLISP. Now you might ask what is AutoLISP and how do I use it? AutoLISP is essentially a coding language mainly used in AutoCAD. It was derived from an early version of XLISP and was created by David Betz. The first version of AutoCAD to use AutoLISP was version 2.18. If you would like to delve into the world of AutoLISP you can find documentation in the help files here. This will assist in getting to know the theory as well as give example code for you to practise on.

When I am looking at automating any mundane task that has been assigned to me, instead of trying to recreate the wheel I look on the internet to see if I can find some code that someone has already done. My go to is the Autodesk discussion forums. I am a firm believer that if I have an issue or a design challenge someone else probably also has had that issue and I can probably find more than 1 solution on the discussion groups. This is the same for coding snippets that might be useful.

If not you can also google for CAD users that have setup websites to share their ideas and routines. The CADalyst site is one that I use frequently.

In conclusion if you are still on AutoCAD LT (and not the latest version) for whatever reason and you feel that a bit of automation will really speed up productivity, install 2024 and see how you workflow can improve with the use of AutoLISP routines.
