Instead of clicking hundreds of polylines, you can use a window selection to calculate the total area in seconds.
If you edit shapes after putting a total area field, use the REGEN command to update the total.
Below is a clean, optimized, and fully functional AutoLISP script. This routine allows you to select multiple closed polylines, circles, regions, or ellipses, calculates their total area, and gives you the option to place the result as text in your drawing.
Requires you to type 'A' (Add) and 'O' (Object), then select shapes individually. Pressing Enter at the wrong time resets your count. total area autocad lisp

: Select all areas and apply a single hatch ; the "Area" property in the Properties Palette (Ctrl+1) will show the cumulative total.
This script assumes a simple use case. Depending on your specific needs, you might need to adjust it. For example, you might want to filter the selection based on layer or color, or handle more complex entities. Instead of clicking hundreds of polylines, you can

A LISP routine designed to specifically write the total area of a closed polyline in square feet ( ft2f t squared ) directly into the drawing. 4. Simple Example: Creating a Total Area LISP
If your drawing units are set to Architectural (where 1 unit = 1 inch), the LISP routine will calculate the total area in . This routine allows you to select multiple closed
In this article, we will explore how to use Lisp to calculate the total area in AutoCAD. We will cover the basics of Lisp, how to write a Lisp program to calculate area, and provide a step-by-step guide on how to implement it.
