PlotNumbering is an AutoCAD LISP script that automates the sequential labelling of land parcels to improve site layout efficiency. This LISP utility provides a streamlined method for assigning sequential numerical identifiers to individual plots within a site plan. It operates by automating the placement of text entities at specified locations, significantly reducing the manual labour associated with drafting large subdivision layouts. The script is designed to handle repetitive annotation tasks, ensuring consistent text formatting and sequential accuracy across complex site geometries. By integrating directly into the AutoCAD environment, it allows users to quickly define numbering sequences, making it a functional component for managing large-scale land development documentation and cadastral mapping requirements.

The download is a single file containing .LSP files.

To implement this tool, load the LSP file into the active AutoCAD session using the APPLOAD command. Once loaded, execute the defined command to initiate the numbering process. Users typically select the insertion points or target boundaries within the drawing, and the script automatically generates the sequential text labels based on the specified parameters. This workflow effectively replaces manual text entry, ensuring rapid updates when site layouts are adjusted during the design development phase.

This script is essential for civil engineers, landscape architects, and urban planners working on subdivision masterplans, housing developments, and large-scale site infrastructure projects. It is particularly useful during the early design and planning stages when frequent revisions to parcel boundaries occur. By automating the annotation process, professionals can maintain high levels of accuracy in site documentation. It integrates seamlessly into standard CAD-based site planning workflows, pairing well with existing title blocks and standard layering systems for comprehensive project delivery.
