This AutoCAD LISP script automates the generation of land parcel grids, creating structured rows of rectangles for subdivision planning. The MakePlots script functions as an automated generator for site subdivision layouts within the AutoCAD environment. It streamlines the drafting process by creating geometric plot boundaries based on precise user-defined dimensions, including width, depth, and the total number of parcels required. By inputting specific variables, the tool calculates and draws arrays of rectangular plots, ensuring consistent spacing and alignment across the site plan. This utility eliminates the repetitive task of manually drawing individual boundaries, providing a reliable and efficient method for establishing parcel grids in early-stage master planning and land development workflows.

The download is a single file containing .LSP files.

To implement this LISP routine in AutoCAD, load the file using the APPLOAD command and execute the assigned command name within the drawing environment. Once active, the script prompts the user for specific parameters such as plot dimensions and the desired quantity of units. The tool then automatically generates the geometry directly into the active drawing layer. Users should ensure their units and coordinate systems are correctly set prior to execution to maintain drawing accuracy.

This script is essential for urban designers, civil engineers, and master planners working on residential subdivision schemes or large-scale land development projects. It is particularly useful during the feasibility and site analysis stages when rapid iteration of site coverage is required. Professionals often use this tool to quickly test various density configurations and lot layouts, pairing it with standard zoning requirements. It is a time-saving solution for anyone frequently tasked with drafting repetitive parcel grids for housing developments or institutional site layouts.
