Blank Canvas: Grasshopper 2 from the Ground Up

GH2 isn't an incremental update to Grasshopper — it's a full rewrite with new data structures, a new component library, and a different underlying approach to building algorithms. The workshop treats "no prior GH1 experience" as a feature, not a gap.

A progressive sequence of guided exercises building fluency with GH2's fundamentals — canvas navigation, data flow, data types, lists, and the components that manipulate them. By the afternoon, participants are assembling multi-step definitions on their own.

Works equally well for absolute beginners and seasoned GH1 users encountering GH2 for the first time — no prior Rhino, Grasshopper, or programming knowledge required.

Learning objectives:

• Understand the GH2 canvas and data flow
• Work with GH2's native data types, lists, and matching behavior
• Use core geometry, math, and logic components for parametric relationships
• Read and debug an unfamiliar GH2 definition
• Understand GH2's architectural differences from GH1
• Access the Rhino MCP GH2 Tools
