AutoCAD remains the industry standard for computer-aided design, but its true power lies in customization. AutoCAD users frequently turn to AutoLISP (LSP) routines to automate repetitive tasks, eliminate manual drafting errors, and speed up project delivery.

All the tools discussed—the original TLEN, Lee Mac's version, TotalLength, and CADstudio AddLen—are available for free. Explore them to find the one that best fits your workflow. Happy drafting, and enjoy the extra hours you'll save.

TlenLSP reads the raw geometric properties of your objects. If your drawing scale is incorrect or if you are working in imperial units (inches) instead of metric (millimeters), the total figure will reflect those base units. Ensure your drawing units ( UNITS command) are set accurately before measurement.
