The Instant Stair plugin, part of a popular series developed by Chuck Vali for Vali Architects, is a specialized extension for SketchUp that automates the creation of stairs and ramps. Unlike traditional modeling methods that require manually pushing and pulling each step, this plugin allows you to generate complex, fully customizable staircases from a simple 2D plan, a centerline path, or a standard shape. It eliminates countless hours of manual work, allowing architects, interior designers, and hobbyists to focus on the creative aspects of their projects.
