Creating StairS 655

Figure 15.45 shows an example using this technique. The tread support elements have been
modeled using blends in order to sweep under the metal plate while changing direction from
vertical to angle. This will accommodate the angled pipe rail that will support the stair.

Treads come together in a particularly interesting stair and railing configuration. There is
obviously a more conventional outer railing for this stair. But the inner railing doesn’t have
any elements that occur at hand height. The entire inner railing exists to support the baluster
supports (which in turn support the default treads). The end post is being used to anchor the
entire structure through the second level. You can find this example, c15-Highlights.rvt, in
the Chapter 15 folder of the book’s companion website. Figure 15.46 shows the finished stair.
The large structural element is actually a baluster that’s been designated as the end post.
