Thanks to professor Michael Erman, and instructor Amrit Singh, a designer at SMBW Architects, for setting this up. Zach Downey was at the Virginia Tech’s college of Architecture and Design teaching an introduction to Parametric/Logical Modeling with Rhino’s Grasshopper. This intense 3-day workshop covered Grasshopper basics and introduced the students to some design problems to solve using Grasshopper’s logical modeling capabilities.
These sessions were recorded and posted on-line for everyone's enjoyment. Here they are http://www.designalyze.com/tag/virginia-tech/
