LABELACRES is an AutoCAD LISP script that automatically computes the area of closed geometric entities and places labels in acres. This LISP utility automates the repetitive task of area calculation for site planning documentation. It functions by scanning selected closed polylines, hatches, circles, ellipses, and regions within a drawing. Once processed, the script generates MText labels representing the calculated area in acres, precisely positioning each text element at the bounding box center of the corresponding object. The tool streamlines the annotation process for large-scale site plans, ensuring consistency in numerical data representation across various geometric types while maintaining the native AutoCAD environment’s drafting standards for text placement and layer management.

The download is a single file containing .LSP files.

Users load this script into an AutoCAD environment using the APPLOAD command. Once active, the tool prompts for entity selection, allowing for batch processing of complex site layouts. It reads the geometric properties of selected shapes and outputs the area data as editable MText objects. Professionals should ensure that the drawing units are correctly configured before running the command to maintain calculation accuracy, and check the generated text style settings to match project-specific CAD standards.

Ideal for landscape architects, civil engineers, and urban planners, this script is essential for large-site feasibility studies and parcel mapping workflows. It significantly reduces manual measurement errors during early-stage master planning, land subdivision, and environmental site assessments. By automating the annotation of expansive outdoor spaces, the tool pairs effectively with site boundary surveys and topographic drawings, making it a standard utility for professionals managing complex land-use projects where quick area verification is required for zoning, permitting, or conceptual design phases.
