On parametric modeling:

Welcome to parametric modeling! While most 3D modeling programs–Rhino and SketchUp inlcuded–allow you to draw information, with parametric modeling, you describe information. It’s the difference between this:

Drawn Line

And this: Line 1

Describing information is powerful becuse it allows you to change one (or many!) component(s) in a system while preserving the integrity of the system itself. For example, if you change the location of Point A, Line 1 will continue to exist, albeit in a changed form: Moved LineIn this case, Point A becomes a parameter that determines a formal outcome. This becomes exciting pretty quickly when you realize that parameters can be created in order to represent everything from water flows to population growth, and more.

In this course, we’ll explore parametric strategies for mapping edges, seams and fields using Grasshopper (a plug-in for Rhino) and CNC fabrication. This blog is meant to be a record of and a source for tutorials, definitions, troubleshooting and ideas. Take a look around, and let us know what you think in the comments!
