Inside Staircase example

One of the most known examples David Rutten is used to show when is presenting Grasshopper is the Staircase example, because is relatively simple to assemble, it's amazing to see the fast-and-easy interactive feedback of parameter changes and, at the end, it's a parametric architectural element. But when teaching Grasshopper, I rather to follow the same constructive approach to generative design —from points, to curves to surfaces— that I've used in RhinoScript, and the Staircase is a good example to introduce Orientation. Therefore, I use it as a fourth or fifth example.

And for not repeating the exact definition that everyone can find on internet, here is another example (with more components, but still simple), in which four points are inputted from the modeling environment to construct a control point (instead of interpolated) curve with degree 2, not used as axial but as an external border generative curve, so that the location of input points can also respond to external parameters like surrounding spaces of a building.
