ObjectARX for Beginners — AutoCAD 2027 / Visual Studio 2026

A hands-on tutorial for writing ObjectARX C++ plug-ins for AutoCAD. Eight lessons take you from a bare "Hello World" plug-in through input & selection, symbol tables, dictionaries & xrecords, custom objects, custom entities, and transient reactors — each one built two ways: entirely by hand, and with the acad-arx-wizard Claude Code skill.

Getting started

Open ObjectARX-Beginner-Tutorial.html in a browser and follow it from the top. It covers what to install and walks through all eight lessons in order.
