Introduction to Conversational Parametric Design: ChatGPT-6 Astra × Rhino

Welcome to Conversational Parametric Design: ChatGPT-6 Astra × Rhino, a 2-day live workshop on PAACADEMY where you’ll learn to use AI to build, modify, and debug parametric models in Rhino and Grasshopper through natural-language prompts. Led by Leo Bieling, Principal at blng studio and former researcher at ZHACODE, the workshop takes you from design intent to working Grasshopper scripts, covering geometry generation, parametric control, iteration, and workflow automation. You’ll leave with practical scripts and a reusable AI-assisted workflow for your own projects.

Methodology:

Get ready for an immersive, studio-style workshop where theory immediately becomes practice. Bring your own architectural reference to deconstruct or work with curated studio precedents as you explore a hands-on, real-world design workflow with industry expertise.

By the end of the course, you will master a reliable, rule-based pipeline to turn spatial ideas into editable 3D geometry. Across two hands-on sessions, you will learn how to:

Deconstruct Geometric Rules: Read architectural precedents as parametric systems, isolating fixed constants, variations, and constraints before writing any text.
Author Clean Pseudo-Code: Structure your design logic into plain language, defining parameters, value ranges, and design rules.
Drive Live Rhino Geometry: Direct ChatGPT-6 Astra to build working scripts inside Rhino 8 and control your models dynamically using live slider interfaces.
Iterate and Debug Through Dialogue: Diagnose misbehaving geometry and refine your parametric output through targeted conversation rather than starting over.
Produce Cinematic Motion: Export viewport captures into Runway to generate styled renders and fluid animated video sequences.

AI models will continue to evolve, but the logic behind computational design remains transferable. This workshop teaches you how to read geometry, structure design intent, and direct AI to build reliable parametric workflows. While ChatGPT-6 Astra is used throughout the workshop, the methodology can be adapted to future generations of AI models.

Key Learning Topics:

Read a building or pattern as a system of rules, and tell a reference with real parametric potential from one that only looks complex
Interrogate an image with ChatGPT-6 Astra so that it returns usable geometric logic instead of generic description
Write pseudo-code for a design: naming the parameters that matter, setting their ranges, and deciding what stays fixed
Turn that logic into a working parametric script for Rhino 8 without writing code yourself
Run a script in Rhino and drive the geometry through a slider interface
Diagnose broken or wrong output and correct it through conversation rather than starting over
Take viewport captures into Runway to produce styled renders and short animations from your own geometry

Program

Day 1: Logic Extraction, Pseudo-Code & Live Scripting:
Begin with an architectural precedent and uncover what makes its geometry work. Through image analysis and discussion with ChatGPT-6 Astra, turn visual patterns into a clear set of rules, relationships, and parameters. These ideas then become pseudo-code and, ultimately, a live parametric system inside Rhino 8. The rest of the day is about making that system respond: pushing sliders, exploring unexpected variations, and using conversation to troubleshoot and reshape the geometry as it develops.

Day 2: Advanced Precedents, AI Renders & Motion:
Take the same approach into more ambitious architectural examples, where multiple rules and parameters interact to create richer forms. Once the geometry is working, shift from making to presenting, developing camera views in Rhino and transforming your models into styled imagery and animated sequences with Runway. The workshop concludes by bringing everything together into a reusable library of prompts, pseudo-code, and working scripts that you can carry into your next project.
