Stair by Component tools is used to produce stair components. It is possible to change type properties and instance properties for the stair components. One can generate a stair by assembling common run, landing and support components. To access stair by component, go to architecture tab — Circulation Panel — Stair by Component.
It should be noted that a stair produced by components cannot be included to an assembly. Apply the Stair by Sketch process to develop a stair that can be added in an assembly.
To produce a component-based stair, you have to select a stair assembly edit mode to include common and custom sketched components.
In stair assembly edit mode, it will be easier to directly accumulate components in a plan or 3D view. Tiling the views can provide you a clear view of the stair model while accumulating it.
