Streamlining Your Workflow: A Guide to AutoCAD’s TLEN.lsp In the world of professional drafting, efficiency is paramount. For AutoCAD users, one of the most persistent challenges is calculating the cumulative length of multiple drawing entities—such as lines, polylines, arcs, and splines—simultaneously. While standard inquiry tools provide individual lengths, the TLEN.lsp routine is a widely recognized solution for calculating total lengths instantly. What is TLEN.lsp?
TLEN.lsp is an AutoLISP routine, a specialized scripting language used to automate repetitive tasks within AutoCAD. Its primary function is to "sum the total length" of all selected objects in a drawing and display the result in a convenient message box. This is particularly useful for quantity takeoff, electrical wiring calculations, or infrastructure planning where linear measurements are critical. How to Download and Install TLEN.lsp
You can typically find this script for free on developer communities and CAD resource sites:
Source Code: You can copy the raw code from repositories like GitHub Gist or download it from dedicated CAD utility sites such as CAD KITS.
Alternative Versions: Variations like "AddLen" or "Totlen.lsp" are also available on platforms like CAD Forum for those needing additional features like layer-specific totals. Implementation Steps
Loading the Script: Once you have the .lsp file, open AutoCAD and use the APPLOAD command. Browse to your file, select it, and click "Load".
Permanent Access: If you use the tool daily, add it to your Startup Suite within the APPLOAD dialog to ensure it loads every time you start AutoCAD.
Running the Command: Simply type TLEN into the command line, select your objects, and press Enter to see the total length. Compatibility and Requirements

What is AutoCAD LT?
AutoCAD LT is a 2D drafting and documentation software that is part of the AutoCAD family. It's a more lightweight version of AutoCAD, focusing on 2D drawing and editing, without the 3D modeling capabilities.
What is LISP (T)?
LISP (LISt Processing) is a programming language used for creating custom applications and automating tasks in AutoCAD. It's a key component of AutoCAD's customization capabilities.
Downloading AutoCAD LT and LISP (T) files
To download AutoCAD LT, you can visit the official Autodesk website, which offers a free trial version. Keep in mind that the free trial is only valid for a limited period (usually 30 days). If you're looking for a permanent free solution, you might want to consider alternatives like:

While the desire to download software for free is understandable, it's crucial to consider the legal and security implications. Whenever possible, opting for official trials or free alternatives can provide a more secure and compliant way to access software tools. For programming and customization within CAD environments, exploring the software's built-in tools and official documentation can lead to effective and legal solutions.
(Total Length) is a popular, free AutoLISP script used in AutoCAD to calculate the combined length of multiple selected objects, such as lines, polylines, arcs, and circles
. Standard AutoCAD properties typically do not display a cumulative length for multiple items at once, making this script a common utility for designers in fields like irrigation or pipeline design Core Functionality : Once the script is loaded, you typically type in the command line to activate it
: You can select objects individually or via window selection. The script then iterates through each item and sums their lengths
: The total length is usually displayed in an alert box or directly on the command line, often respecting the drawing's current units and precision settings Free Download Sources

TLEN.lsp (Total Length) is a popular, free AutoLISP routine used in AutoCAD to calculate and display the sum of lengths for multiple selected objects, such as lines, polylines, arcs, and circles, in a single step. This is particularly useful because standard AutoCAD versions prior to recent updates did not have a built-in feature to sum the lengths of multiple disparate objects at once. Key Features and Uses
Mass Measurement: Automatically sums the individual lengths of various entities into one total value.
Object Support: Typically works with lines, polylines, arcs, circles, splines, and ellipses.
Output: The total length is usually displayed in the command line or a pop-up alert.
Common Applications: Used extensively in fields requiring material takeoffs, such as estimating total piping, cabling, or fencing lengths. Where to Download
