Total Area Autocad Lisp
In this article, we explored how to write a Lisp program to calculate the total area of multiple objects in AutoCAD. The code provided can be easily modified to suit specific needs, such as calculating the total area of objects with specific properties (e.g., by layer, color, etc.). With this Lisp function, you can automate the process of calculating total areas in AutoCAD and save time and effort.
Write your script in the console window. A simple routine typically iterates through a selection set of "AcDbPolyline" or "AcDbHatch" objects and sums their Save the file as a and use the command to load it into any drawing. Practical Applications Cost Estimation
: For land surveying or verifying calculations manually, the command splits polygons into triangles and provides a detailed table of calculation for each piece. Autodesk Community, Autodesk Forums, Autodesk Forum Native Alternatives (No LISP Required) Lisp to calculate area of all closed polylines selected
Calculating areas in AutoCAD is a fundamental task for architects, engineers, surveyors, and designers. While the standard AREA command works for single objects, calculating the total area of multiple, complex, or scattered shapes can be tedious and prone to errors. This is where —AutoCAD’s powerful scripting language—shines. total area autocad lisp
(defun C:TOTAREA ( / ss total area obj_name obj_list i ent) (princ "\nSelect objects to calculate total area: ")
A "Total Area" LISP routine automates this calculation. Once loaded, the script allows a user to simply select a group of closed polylines, circles, or regions. The code then iterates through the selection set, extracts the area property of each entity, and calculates a grand total in seconds. The true power of these routines lies in their customization . A well-written LISP can: Convert Units:
Most "Total Area" Lisp routines (such as the popular or variants found on forums like CADTutor or Lee Mac Programming) operate on a simple workflow: In this article, we explored how to write
: This works, but it requires a 12-step wizard, creates an Excel table, and is overkill for a quick sum.
Ensure the file has a .lsp extension (e.g., TotalArea.lsp ). Load the LISP: Type APPLOAD in the AutoCAD command line. Find the .lsp file and click "Load".
Read your total area instantly in the command line history (press to expand the window if needed). Write your script in the console window
Before diving into LISP solutions, it helps to understand the limitations of standard AutoCAD tools:
Are you working in , civil site mapping , or another specific discipline?
After modifying the shapes, use RE (Region) or a regen command to update the LISP results if they are linked to objects.
You might ask, "Doesn't AutoCAD 2025 have a built-in Total Area tool?"
