Parametric Seating: Overgaard Dyrman Wire Collection

I choose to use the Overgaard Dyrman Wire Collection Dinining Chair as my base for parametric extension.

Original Chair:

I began by building the model in Rhino, basically projecting points from the elevations of the chair and creating curves between these points. From the curves I created a lofted surface. I used the lofted surface to interpolate curves on the surfaces to create the series of wires that create the structure of the chair. From there I was able to split the lofted surface to create the cushion. The legs were made by projected points from the elevations and drawing curves. At the end, I swept circles around the curves to create the piping.

After the model was built in Rhino, I transferred the construction of the geometry to functions in Grasshopper where I was able to add variable sliders to create different outcomes for the width, cushion density and number of bars.
