Function Syntax: AC Version: 1.0 Date: 21.06.2026 5:21:44AM https://forums.autodesk.com/t5/visual-lisp-autolisp-and-general/calc-area-label/td-p/7769387 📐 Function Syntax: AreaCalc 🚀 Command: AC Version: Area Calc v2.1 📐 AreaCalc is an AutoCAD and Civil 3D AutoLISP utility for calculating areas from closed drawing objects, converting units, labeling selected geometry, and creating report output. ✅ It is useful for quantity takeoff, closed polyline area reporting, hatch area schedules, land development drawings, CAD production checks, and Civil 3D plan documentation. 🧭 Main Workflow 🚀 Run AC in the AutoCAD command line. 🔍 Choose an object filter: ANY, POLYLINE, CIRCLE, ELLIPSE, REGION, SPLINE, or HATCH. 📐 Select closed area objects. Open or unsupported objects are ignored. 🪟 The Area Calc v2.1 dialog then controls labels, unit conversion, precision, fields, and report format. 📘 SEO Optimized Description 📐 AreaCalc helps AutoCAD users calculate object areas, convert area units, label geometry, and generate area reports directly from selected drawing entities. 🧮 The command supports square inch, square foot, square yard, acre, square mile, metric units, and additional engineering units. 📊 Results can be written as model space LineText, a native AutoCAD table, a TXT area report, or a CSV file for Excel workflows. 🔗 When field mode is enabled, supported report outputs can include AutoCAD field expressions linked to selected source object areas. 🧩 Functionalities 🔍 Filtered object selection - selects closed polylines, circles, ellipses, regions, splines, and hatches. 📐 Area calculation - calculates each selected object area and builds a total value. 🧮 Unit conversion - converts from drawing units to a selected target area unit. ➕ Additional conversion column - adds a second converted value when required. 🔢 Precision control - supports decimal precision from 0 to 8 with LUPREC fallback. 🏷️ Automatic labels - places numbered MText labels using a custom prefix and starting number. 🔗 Field support - builds AutoCAD object field expressions for live drawing based values when available. 📊 Multiple report formats - outputs to LineText, native AutoCAD Table, TXT, or CSV. 💾 External report export - writes TXT and CSV reports to the AutoCAD support path and opens the file in Explorer. ↩️ Undo safe operation - wraps the workflow in an AutoCAD undo mark and restores command echo settings. ✅ Practical Result The final result is a clean AutoCAD area schedule with object labels, converted area values, totals, and an output format suitable for drawings, reports, or Excel based quantity workflows. ⚠️ Important Notes Only valid closed objects can be calculated. TXT and CSV report types do not keep live AutoCAD field links. External TXT and CSV files are written to the AutoCAD support folder derived from ACAD.PAT.
