To use this step-by-step tutorial, you’ll need an existing Revit model containing at least two floor levels.

1. Insert Stairs. In the Project Browser, double-click on the Floor Plan view corresponding to the lower of two floors you wish to join with a stair. On the Ribbon: Architecture > Circulation > Stair (Stair by Component). Next, on the Ribbon: Modify | Create Stair > Components, choose Run, and then click in the floor plan to begin the stair.

2. To create a single-run stair: move the mouse in the direction of the stair run until Revit reads “0 remaining” risers. Click to complete the stair. Finally, click the green check mark.

3. To create a switchback (double-run) stair: move the mouse in the direction of the first run for the desired number of risers. Click to complete the run. Move the mouse to the starting point of the next run and click to start. Move the mouse in the direction of the second run until Revit reads “0 remaining” risers. Click to complete the stair. Finally, click the green check mark.

4. Create Openings in Floors. In the Project Browser, double-click on a floor plan. Window the entire model to select it. On the Ribbon: Modify | Multi-Select > Selection > Filter. Uncheck all selection categories except Floors.

5. Next, on the Ribbon: Modify | Floors > Mode > Edit Boundary. Then, on the Ribbon: Modify | Floors > Edit Boundary > Draw, choose Boundary Line. Use the Draw tools (and other tools as needed in the Modify panel) to draw the required boundaries. When complete, on the Ribbon: Modify | Floors > Edit Boundary > Mode, click the green check mark to complete the sketch.
