Overview

{THIS IS A FREE TRIAL VERSION LIMITED TO MAX TOTAL LENGTH OF 1000 m}

Length Master is a powerful yet easy-to-use Autodesk® AutoCAD® plugin designed to calculate the total length of specified objects in your drawing.

It provides engineers, architects, and designers with quick and accurate length summaries for linear elements such as cables, pipes, boundaries, and utility networks — all displayed clearly in a dedicated results window.

Key Features

• Instantly calculate the total length of geometry in your AutoCAD drawing.
• Supports Lines, Polylines, Arcs, and Splines, individually or combined.
• Choose to include specific layers or all layers.
• Filter by specific color or analyze all colors.
• Results are displayed in a custom form window, with clear values and formatting.
• Fast, accurate, and user-friendly — ideal for detailed length estimation.
• Fully compatible with AutoCAD environments used for infrastructure, utilities, and engineering workflows.

How Does It Work?

1. Open your drawing in AutoCAD.
2. Run the command “LMR” in the command line or simply press the "Length Master" icon in the Add-ins tab.
3. Define which object types to include - lines, polylines, arcs, splines, or any combination.
4. Optionally select a layer or color filter or leave the default value (--All Layers-- & --All Colors--).
5. The plugin scans the drawing and displays the total length results in a clear, organized form window, allowing you to review and copy the values easily.

Use Cases

• Estimating pipe, cable, or duct lengths in infrastructure utility networks.
• Measuring road centerlines, plot boundaries, or paths in civil and architectural layouts.
• Summing profile or cut lengths in mechanical and MEP designs.
• Checking curve and spline lengths in freeform geometry or concept models.
• Producing quick material take-offs and length summaries for reports or costing.
