I want the stair to look like this.
When I finished it looked like this.. sad face…
A stair Run has two options for Underside Surface: Smooth and Stepped. Smooth is what I started with.
There are occasions when I want the underside to look like the second image above, if so I’d probably tackle that like THIS POST. In this situation I wanted the following appearance. I got it by changing the Structural Depth parameter to match the height of the stair.
