AnnotateArea is an AutoCAD AutoLISP script designed to automate the labeling of closed polyline areas within drafting projects. This AutoLISP tool functions as a streamlined automation script for the AutoCAD environment, specifically developed to handle quantitative annotation tasks. It processes closed polyline geometry to calculate surface areas and automatically generates text labels at the centroid or user-defined insertion point of each shape. The utility is designed for high-speed batch processing, allowing drafters to tag multiple zones simultaneously. It eliminates the manual calculation and text entry steps typically associated with area schedules, ensuring that the displayed data remains consistent with the underlying geometric properties of the selected closed polylines.

The download is a single file containing .LSP files.

To implement this tool, load the LSP file into your current AutoCAD session using the APPLOAD command. Once loaded, execute the defined command to initiate the area-tagging function. Users can select multiple closed polylines in a single operation, with the script automatically calculating the area and placing a corresponding text object on the active layer. It is advisable to verify text height and precision settings within the script parameters prior to large-scale deployment across complex site plans.

This script is essential for land development, urban planning, and large-scale residential projects where rapid area quantification is required for site coverage analysis or zoning compliance. It serves as a time-saving utility for architects and civil engineers who frequently manage complex site plans, landscape designs, or industrial floor layouts. By integrating this into your standard drafting workflow, you can significantly reduce errors in area reporting and streamline the documentation process for planning applications, building permits, and preliminary site feasibility studies.
