Lisp — Total Area Autocad

To calculate the total area of multiple objects in AutoCAD using Lisp (AutoLISP), you can use a simple script that sums up the areas of the selected objects. This script will work with entities like polygons, polylines (2D), circles, and arcs, provided they are closed and have an area.

AREATOT: A common generic command in many scripts that simply prints the sum of all selected objects to the command line. total area autocad lisp

For a professional drafter, learning to load and modify a simple Lisp like TOTAREA is a rite of passage. It is the single highest ROI automation you can implement today. To calculate the total area of multiple objects

Tips and enhancements

• To get results in a specific unit (e.g., square meters), set scale = unit conversion factor at top of routine.
• To include area of closed polylines that are nested (holes), consider converting polylines to regions and using boolean operations — then read Region areas.
• For production use, wrap clipboard calls in error handling and remove OS-specific calls if running cross-platform.
