Utile Cadastru is an AutoLISP plugin for AutoCAD designed to streamline cadastral workflows through automated polygon processing. This utility suite provides a collection of specialised commands tailored for land surveying and parcel mapping tasks within the AutoCAD environment. The toolset focuses on geometric manipulation, specifically enabling users to merge and split complex polygons efficiently. It includes automated routines for running topology checks, which are essential for maintaining data integrity in large-scale cadastral datasets. Additionally, the script features diagnostic tools that highlight open polylines, allowing for rapid identification and correction of drafting errors that would otherwise prevent the creation of closed boundaries or accurate area calculations.

The download is a 72 KB file containing .LSP files.

To integrate this script, users load the LSP file directly into the AutoCAD environment using the APPLOAD command. Once loaded, the utility registers custom commands that can be executed directly from the command line. These functions operate on existing polylines and closed loops, automating repetitive geometric tasks that are typically performed manually. The script is designed to be lightweight, ensuring it does not interfere with standard CAD performance while providing significant time savings for complex parcel geometry operations.

The plugin is intended for professional land surveyors, civil engineers, and urban planners working on cadastral projects, property boundary mapping, and site analysis. It is particularly effective during the initial phases of land development where accurate parcel definition and topology verification are critical. By automating the cleanup of survey data, it assists in the preparation of legal plans and site documentation. It is a valuable addition to any workflow involving large-scale land subdivision, urban infrastructure mapping, or municipal planning documentation within AutoCAD.
