Total Area Autocad Lisp exclusive 【Certified — HOW-TO】

In the daily grind of drafting and quantity surveying, calculating areas from polylines can be one of the most repetitive and error-prone tasks. Standard AutoCAD commands (like AREA with the Object option or LIST ) are functional but limited—they only give you one area at a time, and they don't sum multiple selections.

While AutoCAD's native AREA command allows for "Add Area" functionality, it can be tedious for large numbers of objects. Below are the best ways to achieve a complete "Total Area" feature. 1. Built-in "Quick" Methods (No LISP Required) total area autocad lisp

: To generate a table listing each individual area alongside the total, use the Area Table Lisp ) which labels each polygon. Automatic Text Labels In the daily grind of drafting and quantity

For users needing precision and support for modern AutoCAD features, Total Length & Area program is a standard in the industry. Lee Mac Programming : To generate a table listing each individual

(defun total-area () defines a new Lisp function named total-area.
(setq total 0) initializes a variable total to 0. This variable will store the total area.
(setq ss (ssget "_:L")) gets a selection set of all objects in the drawing.
(setq count (sslength ss)) gets the number of objects in the selection set.
The (repeat count ...) loop iterates through each object in the selection set.
(setq ent (ssname ss 0)) gets the first object in the selection set.
(setq area (vla-get-Area (vlax-ename->vla-object ent))) gets the area of the current object using the vla-get-Area method.
(setq total (+ total area)) adds the area of the current object to the total variable.
(ssdel ent ss) removes the current object from the selection set.
(princ "Total Area: "), (princ total), and (princ "\n") print the total area to the command line.

How to Create a Total Area AutoCAD LISP (and Use It)

Reliability on Geometry: The Lisp is only as smart as the geometry. If your polyline isn't perfectly closed (a common issue in messy drawings), the Lisp may skip it or return an incorrect area. It requires clean drafting habits.
No "Out of the Box" Support: Since these are custom scripts, they aren't installed by default. You have to load them via APPLOAD. For office environments, a CAD Manager usually has to deploy them to all users to ensure everyone is using the same version.
Selection Set Confusion: If you have a complex drawing with overlapping polylines, it is easy to accidentally select an item twice, doubling your total area. You must verify your selection set (sometimes using the QSELECT or SELECTSIMILAR commands first helps).

A2F (Area to Field):

Often attributed to creators like Lee Mac, this script creates an MText object that displays the area as a linked field.
