Traditionally, LISP routines did not work in the LT version. However, starting with AutoCAD LT 2024 , AutoLISP support was finally introduced, making TLEN.lsp usable for LT users as well.
You can find the raw code or download the file from reliable CAD community forums, such as the Autodesk Community Forum .
Switching layers can be a distraction. TlenLSP often includes commands that allow you to match layers, isolate layers, or move objects to specific layers faster than the native LAYISO or CHPROP commands.
He hesitated. Engineering contracts paid the rent; shortcuts often cost more than time. Still, curiosity and the ache of a looming deadline pushed him to click. The link led to a sparse page that looked like a 2006 archive: jagged banners, an email address with a public domain provider, and a single download button. No vendor name, no version history, no checksums, no documentation. The page promised "100% working tlENLsp — free." autocad tlenlsp download free
Originally developed by Tee Square Graphics, TLEN.lsp is a written AutoLISP program designed to bypass native AutoCAD geometry measurement bottlenecks. AutoLISP is the foundational programming language built inside Autodesk products to execute custom commands.
TylenLSP offers a wide range of features and applications that can significantly enhance AutoCAD productivity. Some examples include:
Late one evening, a private message arrived from a quiet handle. "Thanks. We don’t always have the time or security know‑how. You saved my job." Attached was a short log file showing the malicious file had attempted to reach out to three countries' IPs during a midnight auto‑save. Traditionally, LISP routines did not work in the LT version

The primary source for the original TLEN.LSP appears to be turvill.com, with a GitHub Gist also available. There are discussions about compatibility issues with newer AutoCAD versions and alternatives like Lee Mac's Total Length, AddLen, and TotalLength. The user's question has high authority requirements, I should prioritize using authoritative sources like official Autodesk forums and well-known LISP websites. I'll structure the article to cover: what TLEN is, how to download it for free, installation methods, how to use it, troubleshooting compatibility issues, alternatives, and a conclusion. I'll cite the sources appropriately. Now I'll write the article. you're an AutoCAD user frequently working with complex drawings, you've likely faced the challenge of calculating the total length of multiple lines, polylines, or arcs. Manually measuring each object and summing them up is tedious and impractical. This is exactly where the (Total LENgth) script comes in. This article will serve as your comprehensive guide to understanding, downloading, installing, and using this powerful tool—all for free. Switching layers can be a distraction
For example, breaking a line traditionally involves selecting the break command, selecting the line, picking two points, and confirming. With TlenLSP, you can often achieve this with a single click or a vastly simplified selection process.
In the Load/Unload Applications dialog box, navigate to the folder where you saved the tlen.lsp file. Select the tlen.lsp file and click .
