Example: Degree of Complexity “Sheet 7”
“Polygonal continuous surface formed in multi-centric conical curves with added edges (edges include multi-centric tapered spirals)”
A multi-centric conical curve could be built from pieces cut from a series of cones, with some parts reversed and joined edge-to-edge with others. The assembled master part would then be cut to an odd outline (as it would if it had to nest against an uneven surface) and these edges require the addition of a formed flange.
“Aluminum, steel, stainless steel, acrylic, curveply with limitations on minimum radius, sheet fiberglass, stone”
All are semi-rigid sheet materials that can be formed in a single curvature, but not a compound curvature without an expensive expert process.
“CNC rolling, continuous adhesive bonding or welding of all edges and corners, welding and flush finishing. Stone milled and polished”.
Processes are all off-the-shelf, except for milling of stone which is relatively expensive.
“Blind studs, edge hangers, adhesives, through fastened with flush fasteners, interlocking. Forms required for assembly”.
Most materials suffer from varying degrees of springiness, meaning that they will spring back towards their original shape when released from a forming machine. For this reason forms are needed to control shapes until they have their edges installed, or they are fastened to a sub-frame. Frms aren’t as expensive as molds, but there is a cost.
“Building cladding, wall panels, screens, column covers, store fixtures etc. with free form geometry”.
The accompanying images of the Deegies carma store fixtures designed by Gensler and fabricated by Feature factory are examples of this category of geometry.
