# Grasshopper Masterclass: Parametric Facade Generator > Architectural facades have become one of the defining features of contemporary buildings. Beyond shaping a project's visual identity, they must also satisfy structural, environmental, functional, and financial requirements. As buildings become more complex, designing façade syst… ## At a glance - Format: On-demand course - Price: €105.00 (list €140.00) - Difficulty: Beginner - Duration: 8 Hours - Schedule: Sep 12-13, 2026 - Instructors: Ognjen Graovac - Categories: Architectural Design, 3D Modeling - Software: Rhinoceros 3D, Grasshopper 3D, LunchBox, Human, Graphic Statics 3D - Students: 34 - Rating: 4.0 / 5 - Canonical: https://paacademy.com/course/grasshopper-masterclass-parametric-facade-generator - Enroll: https://paacademy.com/course/grasshopper-masterclass-parametric-facade-generator --- ## About this course Grasshopper Masterclass: Parametric Facade Generator is a 2-day advanced computational design workshop where participants build a complete facade generator tool from scratch in Grasshopper and Rhino 8. The workshop covers panel grid creation, data tree management, geometric transformation, metadata attachment, mesh optimization, and automated CSV export of panel quantities and cost data. All techniques are demonstrated through real architectural facade case studies using LunchBox, Human, and Graphic Statics 3D plugins. ## What you'll learn - Creative algorithmic thinking and problem solving - Building robust Grasshopper definitions - Debugging complex algorithms in Grasshopper - Working with geometric transformations - Optimizing algorithms for performance - Attaching metadata to generated geometry - Automating repetitive workflows such as baking thousands of facade elements ## Methodology In this workshop, we will focus on developing parametric models in Grasshopper and organizing a large number of highly detailed façade elements in Rhino. This includes explaining many useful tips, tricks, and techniques for both Grasshopper and Rhino workflows. For example, we will cover data tree management, geometric transformations, reusable algorithms, attaching metadata to geometry, optimizing mesh geometry, and many other useful computational design techniques in Grasshopper. In Rhino, you will learn how to automatically bake and organize thousands of façade blocks generated by your algorithm. All of these parametric techniques will be demonstrated through real-world façade projects, allowing you to understand not only how the algorithms work, but also how they can be applied in professional architectural practice. The workshop is intended for architects, designers, engineers, and students who already have a basic understanding of Rhino and Grasshopper and would like to improve their computational design skills. ### Scope: The workshop will combine theoretical explanations, step-by-step demonstrations, and practical exercises. Each part will begin with a short introduction to the main design problem and the Grasshopper techniques that will be used to solve it. After that, the complete workflow will be demonstrated through a real-world facade example. The workshop will follow a gradual learning process. We will begin by defining the main façade parameters and studying the input geometry and architectural drawings. The next steps will include creating panel systems, generating detailed façade elements, and attaching relevant metadata to the geometry. The complete facade generator will be divided into smaller, clearly organized parts. This will allow students to understand each part of the algorithm separately before combining everything into a complete parametric system. Particular attention will be given to building clean, scalable, and efficient Grasshopper definitions that can manage a large number of façade elements. Students will follow the demonstrations and complete practical exercises individually. During the workshop, they will be encouraged to test different parameters, explore design variations, and adapt the demonstrated workflow to their own ideas. ### Program: **Day 1: Building the Parametric Facade System** - Study façade details and define key design parameters. - Create adjustable panel grids and surface subdivision systems. - Learn data tree management for organizing façade components. - Generate parametric panels, frames, openings, and supporting elements. - Build a clean, scalable Grasshopper definition from scratch. **Day 2: Optimization, Automation & Documentation** - Develop detailed façade elements, including mullions, joints, and corner conditions. - Optimize Grasshopper definitions and create lightweight mesh geometry for visualization. - Attach metadata, generate panel IDs, and calculate quantities and cost data. - Export structured façade information to CSV files. - Automatically bake and organize façade elements in Rhino using layers, blocks, and object attributes. ## Requirements - Please note that the software installation process is not part of the workshop. Participants are expected to have Rhino 8 and Grasshopper installed before the workshop begins. - The required Grasshopper plugins are Human and Graphic Statics 3D (3DGS). ## Curriculum ### Session 1 - Introduction & PAACADEMY Updates (12:25) - Presentation, Rhino Model Objects and Filtering (45:48) - Parametric Block Building Data Trees (59:32) - Floor Systems and Controlled Randomness (46:32) - Extrusions, Master Grid Subdivisions and Automated Placement (57:54) ### Session 2 - Parametric Facades and Attractor Logic (48:45) - Distance Remapping and Code Generation (33:00) - Data Tree Matching and Code Filtering (54:00) - Automated Facade Slicing and Level Offsets (38:27) - Panel Metadata and Symmetry Code Extraction (50:18) ## FAQ ### Which software and plugins are needed for the Grasshopper facade design course? The workshop uses Rhinoceros 3D (version 8) and Grasshopper 3D. Required plugins are LunchBox for panel and surface operations, Human for object attribute management and geometry organization, and Graphic Statics 3D (3DGS) for structural geometry. Software installation is not covered during the workshop, so participants must have Rhino 8 and all plugins installed and working before Day 1. ### What does the Parametric Facade Generator masterclass cover over two days? Day 1 focuses on analyzing facade drawings, defining key design parameters, creating adjustable panel grid systems, managing data trees, and building a clean scalable Grasshopper definition from scratch. Day 2 covers detailed facade element generation including mullions, joints, and corner conditions, mesh optimization for visualization, attaching metadata and panel IDs, calculating quantities and cost data, exporting CSV files, and automatically baking and organizing thousands of facade elements in Rhino using layers, blocks, and object attributes. ### Is this Grasshopper masterclass suitable for beginners? This workshop is designed for architects, designers, engineers, and students who already have a basic working knowledge of Rhino and Grasshopper. Participants new to parametric design are encouraged to complete a Grasshopper beginner course first. The workshop focuses on intermediate to advanced computational techniques including data tree management, algorithm optimization, and automated documentation workflows. ### What will I produce by the end of this parametric facade workshop? You will complete a fully functional parametric facade generator — a production-ready Grasshopper definition capable of generating complex facade variations with adjustable parameters. The tool outputs detailed 3D facade geometry in Rhino, optimized mesh models for visualization, and a structured CSV file containing panel IDs, material quantities, and cost estimates. The workflow is reusable and adaptable to future architectural and engineering projects.
