STAIR GENERATOR - Build A Code Compliant Stair with One Line - Grasshopper Script

Stair Generator — Grasshopper Tool for Customizable, Code-Aware Stair Geometry📐 A Grasshopper tool that rapidly generates clean, customizable, code-aware stair geometry from a single input curve. Draw one line, set your parameters, and the script builds the full stair — from the bottom riser to the final top walking surface — aligned to architectural floor-to-floor logic.What's inside📐 Stair Generator Grasshopper definition — the complete parametric tool, ready to drop into your Grasshopper workflow.📏 Single-curve input logic — the tool treats your input line as a controlled stair trajectory, not a vague centerline, resolving cleanly from the first riser to the upper tread or landing.⚙️ Customizable stair parameters — adjust riser, tread, and run settings for predictable, code-aware results.SpecsType: Grasshopper definition (parametric tool) Input: Single curve Output: Code-aware stair geometry Delivery: ⬇️ Instant downloadCompatible withRhinoceros 3D · GrasshopperPerfect forFast design studies where stair logic needs to stay adjustable; schematic stair layouts in early design phases; massing models that need clean, believable stair geometry; presentation geometry for client and jury work; early coordination where floor-to-floor stair alignment matters; architecture students and professionals who want predictable parametric stairs without rebuilding the logic for every project.How to use ⚡ Download the file from your account dashboard after purchase. Open Rhino and launch Grasshopper. Open the Stair Generator definition in the Grasshopper canvas. Draw a single input curve in Rhino as your stair trajectory and reference it into the definition. Adjust the riser, tread, and run parameters until the stair resolves cleanly against your floor-to-floor condition.
