Cappellini Wooden Chair (Marc Newson by Merav Lahr)

For the parametric seating assignment, I choose to work with Marc Newson’s wooden chair for Cappellini.

The chair is made of 3 parts: a curved, triangular base; 4 curved rectangular frames; and, 20 ribs, each a different size.

HOW ITS MADE

In Rhino, I drew the curved line for each piece of ribbing and swept a rectangle along it. For the frame, I used arcs and rectangles along with the sweep tool; for the base, arcs and triangles with the sweep tool. Below are 4 views of my model (clockwise from top left: front elevation, left elevation, plan view, perspective):

For the second half the assignment, I will use Grasshopper to explore the following design drivers:
