Short description
📏 TLength is an AutoCAD AutoLISP utility that calculates the total length of selected drawing objects and copies the numeric result directly to the clipboard.
Command:
TLENGTH
Description:
📐 TLength helps AutoCAD and Civil 3D users measure combined object lengths quickly from the command line.
🚀 Run the TLENGTH command, select supported geometry, and the tool sums the total length or perimeter using AutoCAD ActiveX curve data. The result is printed in the command line and copied to the Windows clipboard as a clean numeric value with four decimal places.
🧰 Supported object types include LINE, POLYLINE, LWPOLYLINE, ARC, CIRCLE, ELLIPSE, SPLINE, MLINE, REGION, and MPOLYGON. This makes it useful for quantity takeoff, drafting checks, linear measurement control, Civil 3D production drawings, CAD auditing, and fast length reporting.
📋 The clipboard workflow makes it easy to paste the calculated value into Excel, reports, labels, schedules, quantity tables, BoQ calculations, or other downstream documentation.
Helper function: (if any)
🧩 c:TLENGTH is the main AutoCAD command function.
📋 copy-to-clipboard creates an htmlfile COM object and writes the measured numeric result to the Windows clipboard.
🔄 vl-load-com support is guarded with a validator-safe COM availability check.
Functionalities:
📏 Calculates total selected length from multiple AutoCAD object types.
📐 Uses vla-get-length for LINE, 3D POLYLINE, and POLYLINE objects.
🧭 Uses vla-get-arclength for ARC objects.
⭕ Uses vla-get-circumference for CIRCLE objects.
🌀 Uses vlax-curve-getdistatparam for SPLINE and ELLIPSE objects.
🧱 Calculates MLINE length from coordinate segment distances.
🟦 Uses vla-get-perimeter for REGION and MPOLYGON objects.
🔢 Formats the final result with four decimal places using rtos.
📋 Copies the final numeric value directly to the clipboard.
🖥️ Prints a single-object or multi-object total length message in the AutoCAD command line.
🧹 Cleans up the temporary AutoCAD selection set after calculation.
Result:
✅ The result is a fast combined length value for selected AutoCAD geometry, displayed in the command line and copied to the clipboard for immediate reuse.
