PolylineArea

Short description

📐 PolylineArea is a compact AutoCAD AutoLISP area calculator for summing the total area of selected polyline objects and copying the numeric result directly to the Windows clipboard.

Command:

🚀 Main command: POLYAREA
🧩 AutoLISP function: C:POLYAREA
📌 Object filter: *POLYLINE

Description:

📐 PolylineArea helps AutoCAD users calculate the combined area of multiple selected polylines in one simple command.
🔍 The routine selects lightweight, 2D, 3D, and legacy polyline-type objects through the *POLYLINE selection filter.
🧮 For every selected polyline, the tool runs the native AutoCAD AREA command with the Object option and accumulates the drawing area value.
📋 The result is automatically copied to the Windows clipboard, making it easy to paste the calculated value into Excel, reports, quantity takeoff tables, BoQ worksheets, or project notes.
🏗️ This is useful for civil engineering, infrastructure drafting, CAD quantity checks, pavement areas, site layouts, closed boundary checks, land development areas, and AutoCAD production workflows.

Helper function: (if any)​

📋 copy-to-clipboard – creates an htmlfile COM object and writes the final numeric area value to the Windows clipboard.
🧮 _.AREA Object mode – reads each selected polyline area through the native AutoCAD command system.
📏 DIMUNIT check – detects imperial dimension settings and formats the result accordingly.

Functionalities:

🚀 Launches from the AutoCAD command line with POLYAREA.
📐 Selects all supported polyline entities using the *POLYLINE object filter.
🧮 Calculates the total area of multiple selected polyline objects.
📏 Supports metric, unitless, and imperial display logic.
🟧 For imperial dimension settings, reports square inches and square feet.
📋 Copies the clean numeric result to the Windows clipboard automatically.
📊 Shows the full total area result in an AutoCAD alert dialog.
🧹 Releases the clipboard COM object after use.
⚠️ Displays a clear warning when no polylines are selected.

Result:

✅ The final result is a fast AutoCAD area-total workflow: select polylines, calculate the combined area, view the formatted result, and paste the numeric value directly into external documentation or quantity reports.
