Challenge Period: Monday, 16 January 2017 - Sunday, 29 January 2017
Spiral staircases are not spirals in the mathematical sense, rather, they are helical in shape and designed to be very space efficient. They can be made of any variety of materials capable of supporting the weight of the staircase and those climbing them.
You can use a variety of built in tools and extensions in SketchUp to accomplish modeling of a spiral staircase but the design is completely up to you. Just be careful not to let it spiral out of control!
