TLEN cannot read lines that reside inside an unexploded block or an external reference (Xref). You must explode blocks or open the Xref directly to measure those linear elements.

The AutoLISP script solves this limitation. This specialized macro aggregates the lengths of all selected objects instantly. It eliminates manual arithmetic, reduces data extraction errors, and significantly accelerates quantities takeoff for budgeting and design validation. What is TLEN.lsp? autocad tlenlsp download best
For advanced users who need detailed, report-style data.
Measures lines, polylines, 3D polylines, arcs, circles, and splines. TLEN cannot read lines that reside inside an
AutoCAD LT is a lightweight version of AutoCAD, a popular computer-aided design (CAD) software used by architects, engineers, and designers. AutoCAD LT is designed for 2D drafting and documentation, and is ideal for users who don't need the advanced features of the full version.
Once you have downloaded the .lsp file, follow these steps to get it running: 1. Loading the LISP Routine There are two primary ways to load the file: Whether you are estimating electrical wiring
The primary purpose of TLEN.lsp is to calculate the of a group of selected objects, such as lines, arcs, polylines, circles, or splines.
If you’ve ever found yourself clicking ten different polylines and staring at a "Varies" message in the Properties palette, you know the frustration of calculating total lengths. Whether you are estimating electrical wiring, fencing, or piping, you need a faster way.
: If you prefer a "plug-and-play" experience, the TotalLength add-in provides similar functionality with a verified download.
Instead of manually creating layers for "Existing Ground," "Proposed Grade," and "Grid Lines," TlenLSP automates this. It sets standards so that your drawings remain clean and readable.
