The document discusses a week 2 class on parametric modeling in Rhino and Grasshopper. It covers the Rhino and Grasshopper interfaces, geometry types in Rhino, visual programming in Grasshopper using components, connecting components and data flow, and previews and baking designs to Rhino. It also discusses different component and connection types.
