Master Data Management in Grasshopper 3D

This course offers a clear and practical introduction to lists and data tree structures—essential tools for anyone working with Grasshopper 3D. You'll learn how Grasshopper organizes information, how to navigate and modify data hierarchies. Through a combination of hands-on exercises and conceptual explanations, you'll explore how to use key components to sort, filter, graft, flatten, and structure data for better control in parametric modeling. Whether you're an architect, designer, or digital artist, this course will give you the skills to structure your data and streamline your workflows with confidence.

Designed for beginners and intermediate users alike, this course will help you:

• Understand the logic behind Grasshopper’s data structure

• Work confidently with lists and hierarchical data trees

• Use key components to control and manipulate data paths

• Build cleaner parametric definitions
