The city is a relatively recent organization of society in human evolution – and even though many aspects are already known and surveyed, there are still abundant twilight zones, many of which will be brought to light in this year’s and future conferences. In this two-day workshop we will explore Grasshopper ( customization and write tools which allow designers to take decisions and consider geometric properties and scalar quantities while working on their assignments.

We will put simple geometric rules into practice, and building on them we will construct spatial ideas and metric utilities that help suspend ambiguities and focus on the areas of action/reaction at city district and other subunit levels. We will also discuss on how these tools can then be expanded to cover these grounds further.

To accomplish more with Grasshopper, this training will therefore first investigate scripting components and tinker more complex, interactive solutions using the young and new RhinoCommon ( framework. We will explore programming paradigms like arrays, lists, recursive and incremental analysis. Additionally, we will see how to get started writing Rhino .NET plug-ins. This workshop is based on the .Net Advanced training and is not a pure software tutorial. You are welcome to send suggestions and proposals. More information is to be found here:

The workshop will use C#. At least some knowledge of Grasshopper visual programming is required and a basic knowledge of any programming language is welcome.

Submission information:
Applications to the workshop are invited in the form of brief abstracts (approximately 150-300 words long) formatted according to the eCAADe2010 paper guidelines ( Contributions may include examples of the digital design chain and express interests in using the software in a particular workflow. The submitted contributions will be assessed by the workshop committee, with the view of covering the breadth and depth of the suggested topics.

Please submit your abstracts by emailing the workshop chairs by the 30th of August 2010.

Technical requirements:
Participants are required to bring their own laptops with Rhino 4.0 SR8 or higher and Grasshopper 0.7x or higher. The Rhino Evaluation version can be downloaded from and Grasshopper from

This workshop is open to eCAADe 2010 conference participants only.
