Manually adding each area using a calculator is not only slow but also prone to human error. This is where the magic of comes in. A well-written "Total Area Lisp" routine can instantly sum the areas of selected objects (polylines, circles, hatches, or regions) and present the result in your desired unit—square feet, meters, or even acres.
If you need help adjusting this tool for your specific drawing standards, please share:
This routine links the total area to a FIELD or RTEXT so that if you stretch a polyline, the total updates automatically (requires advanced Visual LISP using reactors).
A classic routine that sums the total area of all selected objects and displays the result in the command line or an alert box.
Are you dealing with (e.g., square feet to acres)? I can help refine the script for your specific workflow. Lisp to calculate area of all closed polylines selected total area autocad lisp
This LISP script is designed to handle LWPOLYLINE,CIRCLE,ELLIPSE,HATCH . If you select an open polyline, the area will not be added because an open shape does not have a mathematically defined "area." 3. Handling Hatches
The script includes HATCH in the selection filter. This is crucial for calculating the total area of complex, filled spaces. Expanding the LISP: Adding Text to Drawing

;; Step 2: Exit if nothing is selected (if (null ss) (princ "\nNo valid objects selected.") (progn (setq total 0.0) ; Initialize total to zero (setq i 0) ; Initialize counter Manually adding each area using a calculator is
Different routines offer various levels of automation, from simple command-line totals to complex reporting:
: Most "Total Area" scripts use commands like TAREA , AREAM , or QSTA .
If you use this tool daily, don't run APPLOAD every time. Type APPLOAD , click the Startup Suite (the briefcase icon), click Add , and select your TotalArea.lsp file. Now, the TA command will be permanently available in every drawing you open.

LISP offers unique benefits, but AutoCAD's native tools might be sufficient in certain scenarios.
: A safety check that confirms the object possesses an inheritable Area property before attempting to read it. This prevents the script from crashing if an unhandled object type slips into the selection.

AutoCAD is a powerful computer-aided design (CAD) software that offers a wide range of tools and features to create, edit, and manage 2D and 3D models. One of the common tasks in AutoCAD is to calculate the total area of multiple objects, such as rooms, buildings, or landscapes. While AutoCAD provides a built-in AREA command to calculate the area of a single object, it can be tedious to calculate the total area of multiple objects manually.
By following these steps, you can create a Lisp routine to calculate the total area of multiple objects in AutoCAD.
If you are new to using custom scripts in AutoCAD, follow these simple steps to install and execute the code: Step 1: Save the Code Open (Windows) or any plain text editor. Copy and paste the LISP code block provided above.
