A key advantage of TLEN is its object support. The classic version of TLEN can handle:

Downloading and Working with TLen.lsp in AutoCAD: The Complete Guide

(defun C:TLEN (/ ss tl n ent itm obj l) (setq ss (ssget) tl 0 n (1- (sslength ss))) (while (>= n 0) (setq ent (entget (setq itm (ssname ss n))) obj (cdr (assoc 0 ent)) l (cond ((= obj "LINE") (distance (cdr (assoc 10 ent)) (cdr (assoc 11 ent)))) ((= obj "ARC") (* (cdr (assoc 40 ent)) (if (minusp (setq l (- (cdr (assoc 51 ent)) (cdr (assoc 50 ent))))) (+ pi pi l) l))) ((or (= obj "CIRCLE") (= obj "SPLINE") (= obj "POLYLINE") (= obj "LWPOLYLINE") (= obj "ELLIPSE")) (command "_.area" "_o" itm) (getvar "perimeter")) (T 0) ) tl (+ tl l) n (1- n) ) ) (alert (strcat "Total length of selected objects is " (rtos tl))) (princ) )

If you cannot find a direct download link, you can easily create the file yourself using standard code snippets shared on forums. Open (Windows) or TextEdit (Mac). Paste the verified AutoLISP code into the document. Click Save As .

The routine works for simple lines but gives zero length for polylines, or the total is obviously wrong. autocad tlenlsp download work

This happens when the TLEN.LSP routine was not loaded successfully, or an old version of TLEN is conflicting with another command. AutoCAD falls back to its own closest‑matching command name.

Ensure you are using a 64-bit compatible routine for modern AutoCAD versions [1].

Before you can use TLEN, you need the actual .LSP file. Because AutoLISP scripts are plain text files, they are often shared on forums, GitHub, and community pages. However, not all sources are trustworthy. Below are the recommended ways to obtain the original or a well‑tested version of TLEN.LSP.

While AutoCAD has built-in tools like MEASUREGEOM or the Properties palette, they often require you to click objects one by one. TlenLSP automates this by processing multiple objects simultaneously. Key Features of TlenLSP A key advantage of TLEN is its object support

Follow the instructions in the “Making TLEN Load Automatically” section above to add the file to the Startup Suite.

Some custom versions of TLEN use a different command name. If TLEN does not work after loading, look at the command line feedback. The message might say C:LL or something similar—that is the actual command name you need to type.

If you are using AutoCAD LT (Light), LISP routines will not work out of the box on older versions. Autodesk only introduced native AutoLISP support to AutoCAD LT starting with the .

Even with a simple tool, things can go wrong. Here are the most common fixes: Paste the verified AutoLISP code into the document

Continuing to research and implement these automation tools is a standard practice for advanced CAD users looking to maintain a competitive edge in design and engineering fields. Share public link

For most users, TLEN remains the best balance of simplicity and power. It is free, requires no installation beyond dragging a file, and does exactly one job efficiently.

Optional but Recommended: Add the file to your "Startup Suite" so that it loads automatically every time you open AutoCAD. Step 2: Running the Command

Many online code repositories or user forum text pastes corrupt the base script string by appending hidden web format elements or altering loop parameters. Ensure your local .lsp document utilizes clean, basic logic blocks like the example below:
