When you create a stair, you can modify the individual components of the stair, including the runs, landings, and supports. You can also make modifications to the entire stair, like changing the stair type or changing the location.
Modifications to one component may directly affect other components in the stair to maintain the design intent and integrity of the stair assembly.

Important: When you create components by sketching, they do not have the automatic relationship to each other as when stair components are created with the common component tools. For example, if you sketch run and landing components, then change the run width, the landing shape will not change automatically. Sketched components must be updated manually.
