Complete Stair Generation Workflow in Grasshopper 3D | 7fold Modeling

This start to finish tutorial in Grasshopper 3D demonstrates how to design a fully parametric staircase. Learn how to program flexible tread depths and riser heights while following a set floor to floor height and driven by a Rhino-modeled curve and tread design of your choice. Learn how to use the best of Rhino and Grasshopper together to boost your productivity and quickly generate a custom stair in no time. This tutorial is geared for beginner to intermediate users of Grasshopper focusing on learning through doing.

This tutorial covers how to use the following key components in grasshopper : divide curve by distance, sort by key, relative item component, organize planes by a vector tangent to the input curve, loft between 2 curves on different branches, correct plane sorting direction based on evaluate surface to offset a curve and build a new surface from edge curves.
