The second edition of the Grasshopper Primer is out and it wouldn't have been possible without the tremendous contribution from Rajaa Issa. Rajaa is a developer at Robert McNeel and Associates and is the author of several other Rhino plugins including ArchCut and the ever popular PanelingTools. This revision provides a much more comprehensive guide than the first edition, weighing in at almost 160 pages with over 70 new pages dedicated to creating your own customized scripting components.
This printing coincides with two events; the first being the new release of Grasshopper version 0.6.0007 which proves to be a giant upgrade to the already robust Grasshopper platform. Existing users will find subtle, and some not so subtle changes to how data is stored in the current version; making some previous definitions outdated or even unusable. It is the hope that this primer will help new and existing users navigate many of the changes to the software system. The second event that overlaps with this publication is the conference titled FLUX: Architecture in a Parametric Landscape that is being held at the California College of the Arts. The event explores contemporary architecture and design through its relationship with changes in design technologies such as parametric modeling, digital fabrication, and scripting. Among other things, the event will consist of an exhibition and a series of workshops dedicated to parametric software systems.
