Function Syntax: Polyarea https://gist.github.com/kevinluo201/ca895bd422fd6b289993268fc35b3191 📐 PolylineArea - AutoCAD Polyline Area Calculator 🚀 Run POLYAREA in the AutoCAD command line to calculate the combined area of selected polyline objects. SEO Friendly Description 📐 PolylineArea is an AutoCAD AutoLISP utility for fast polyline area calculation, CAD quantity takeoff, boundary area checking, pavement area reporting, site layout measurement, and Civil 3D drafting support. 🧮 The tool selects supported polyline objects with the *POLYLINE filter, runs AutoCAD's native _.AREA command in Object mode, and sums the total drawing area. 📋 The calculated numeric value is copied automatically to the Windows clipboard so it can be pasted into Excel, BoQ tables, reports, calculation sheets, or project documentation. Main Command 🚀 POLYAREA - select one or more polylines and calculate their total area. Functionalities 📐 Polyline area selection - filters the selection to polyline-type objects using *POLYLINE. 🧮 Total area calculation - loops through the selected polylines and accumulates the AutoCAD area result. 📏 Imperial unit handling - when DIMUNIT indicates imperial display, the tool shows square inches and square feet. 📊 Metric and unitless output - reports the selected polyline area as square drawing units. 📋 Clipboard export - copies the numeric result automatically for use in spreadsheets and documentation. 🔔 Result alert - displays the final total area in an AutoCAD alert dialog. 🧹 Safe cleanup - releases the clipboard COM object after copying the value. Practical Result ✅ The result is a quick AutoCAD workflow for calculating total polyline area and transferring the final value directly to Excel, BoQ reports, quantity takeoff sheets, or project notes. Important Note ⚠️ The routine uses AutoCAD's native AREA behavior, so open, invalid, or self-crossing polylines may produce results according to AutoCAD's own geometry interpretation. 🔒 The command is read-only for drawing geometry and does not modify selected polylines.
