Total Area Autocad Lisp Jun 2026

This tool represents the pinnacle of what's possible with AutoLISP for QTO, turning a manual, error-prone process into an automated, reliable system.

In AutoCAD, calculating the total area of multiple objects—like polylines, circles, or regions—can be tedious if done manually using the standard AREA command. AutoLISP routines automate this by summing the areas of all selected objects and displaying the result instantly.

Assumes your drawing units are in feet. Change the conversion multipliers if you work in meters or millimeters.

Whether you need the final total printed as total area autocad lisp

This routine not only calculates the total but also writes it into the drawing as a MTEXT object.

: High-quality, free routines can be found on sites like Lee Mac Programming or JTB World .

Tips for Accurate Area Calculations This tool represents the pinnacle of what's possible

Calculating the total area of multiple objects in AutoCAD can be done using various built-in features or custom AutoLISP routines.

AutoCAD LISP (AutoLISP) routines solve this problem. A LISP script automates the repetitive clicking, extracts geometry data instantly, and displays the cumulative total. This guide covers how to use, install, and write a custom Total Area LISP routine to speed up your drafting workflow. Why Use a LISP Routine for Total Area?

Before we dive into writing a Lisp program to calculate total area, let's cover some basic concepts of Lisp: Assumes your drawing units are in feet

Modify the routine to exclude hatched areas representing voids, or to sum only polylines on layer "A-FLOR-SEAL".

You might ask, "Doesn't AutoCAD 2025 have a built-in Total Area tool?"

The logic generally follows these steps:
