Built for AutoCAD

Subdivision Toolkit

Twenty-seven powerful layout tools that turn hours of civil subdivision drafting into a few clicks — built by a professional AutoCAD operator, for professional AutoCAD operators.

The Subdivision Toolkit is a LISP add-in that plugs straight into AutoCAD and automates the repetitive, error-prone parts of subdivision layout — lotting, road centerlines, setbacks, labeling, and sheet output. It was hand-built by Stephen Smith over years of real civil work, so every command does exactly what a drafter actually needs, the way they'd actually do it.
