Presented by The Architect's Newspaper and enclos, they recently announced that an additional workshop will take place on Friday, April 12. This workshop will focus on the fundamental concepts and workflows for creating performance-based design models with the parametric design tool, Grasshopper for Rhino3D. Using Grasshopper, participants will be guided through a series of exercises designed to emphasize the relevant applications of parametric design for professional practice.
