This is a remake of an old tutorial - as the data structures in the most recent version (06.0059) of grasshopper have changed - and the old way of constructing this surface will no longer work. This is a good beginning coverage of the parameter viewer tool and dealing with data trees - shows how you can use the tool for splitting a longer list of paths into smaller ones. For reference you can upload the definition here.
Generative Design Computing.net
is a site that focuses on the utilization of computers in the design and fabrication of architecture, objects, installations, experimental work... The site primarily functions in support of several classes that I conduct at the Taubman College of Architecture and Urban Planning at the University of Michigan. They are Arch 591: Generative Design Computing, Arch 571: Digital Fabrication, and Arch 421: Geometric Modeling in addition to Graduate Design Studios. The site is also both an archive of video tutorials generated from those courses and a digital sketchbook of student work and related digital productions. In addition to teaching I’m also part of the design practice (area-architecture.com)
