Mastering Total Area Calculation in AutoCAD: The Ultimate Guide to LISP Routines

: Save your LISP code as a .lsp file (e.g., TotalArea.lsp ).

1. Selection: You select multiple closed polylines (LWPolyline) or objects at once.
2. Recognition: The Lisp script iterates through the selection set, filtering only the valid closed polylines.
3. Calculation: It sums the area of every selected object.
4. Output: It returns a total area in the command line, and often allows you to insert a text label into the drawing with that total.

This is where Lisp comes in – a programming language that allows you to create custom functions and automate repetitive tasks in AutoCAD. In this article, we will explore how to write a Lisp program to calculate the total area of multiple objects in AutoCAD. total area autocad lisp

• 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).

Load the Script

: Save the code above as a .lsp file and drag it into your AutoCAD drawing, or use the APPLOAD command. Run the Command : Type TOTALAREA in the command line. Mastering Total Area Calculation in AutoCAD: The Ultimate
