Measuring multiple lines, polylines, and arcs in AutoCAD can be a repetitive task. Manually summing their lengths is not only time-consuming but also prone to errors.

To solve this, CodeHaks TotalLength offers a simple, dedicated interface to automate this process. It’s a lightweight add-on designed specifically for AutoCAD 2024 and 2025.

What is CodeHaks TotalLength?

CodeHaks TotalLength is an open-source AutoCAD plugin that calculates the total length of selected objects (lines, polylines, arcs) instantly. It provides a clean UI to filter object types, view the object count, and get the aggregated length — all with a few clicks.

Key features

  • Object filtering — select specific types (Lines, Polylines, Arcs) or all at once.
  • Instant calculation — displays the total length of the selected set immediately.
  • Object count — shows how many objects were counted in the selection.
  • User-friendly interface — a simple, non-intrusive window that keeps you productive.
  • Easy command — launch the tool using the ZLen command.
