Folding in Parametric Architecture

 

Folding via stretching

This week, I examined folding in Parametric Architecture and it’s types with some examples which are Folding Based on Surface, Folding Based on lines and Folding Based on 3D objects.

“Folding is an effective method for making three-dimensional form because it turns flat material into the third dimension. Apart from its formal qualities you can gain structural stiffness into otherwise planar materials by introducing folds into material to increase the selfsupporting effective span and rigidity of your design. Creased surfaces, folded plates and wrapped volumes are methods of folding. In architectural design folding is also quiet often achieved through stretching the surface. Characteristic is always the continuity of space folded surfaces create. If you are able to unroll or unfold the surfaces of your design into two dimensional surfaces for digital production than you can produce your design efficiently with CNC milling and laser cutting.”(Digitales Entwerfen).

1) Folding based on surfaces (freeform)

“You can transform a two-dimensional surface into three-dimensional form. This method is an efficient way to create foldings based on the topology of your 2D surface.”(Digitales Entwerfen).

2) Folding based on lines

 “2D lines (or smooth spline lines) are a good starting point of folded structures via stretching. You can create several lines at different position in Z dimension and connect them to a three dimensional surface. The big advantage of this method is that you have a really good control of your design because you can readjust the position of the lines and the position of the vertices inside the lines.”(Digitales Entwerfen).

3) Folding based on 3D objects

“If you stretch, twist and deform 3D objects you can easily get folded structures. The result depends mainly on the basic topology of your 3D object. The pattern and structure of your tessellation has a big impact on your result. The result of this method is mainly based on triangulated surfaces and not easy to control for further adjustments. But it is a fast and efficient way for your first conceptual design.”(Digitales Entwerfen).
