In this exercise, we will add a simple egress stair to our model.
Catch-up file completed to this point: 13_Medical Center_Stair.rvt
First, we need a location for the stairs.
Figure 13–1 Copy and paste the walls to Level 1
A warning will appear in the lower right corner indicating that walls overlap. It is safe to ignore this. We will fix the problem now. The walls we pasted have a 3'-0" top offset. We need to set this to zero.
Take note of the context buttons on the Modify ribbon. There is one labeled: “Show Related Warnings.” If you missed the warning and dismissed it too quickly, this would allow you to see it again (see Figure 13–2).
Figure 13–2 A warning accompanies the pasting of these walls
Notice that the “Show Related Warnings” button is no longer displayed. This is because we have resolved the previous warning (see Figure 13–3).
Figure 13–3 Once the warning is resolved, the Show Related Warnings button will disappear
Figure 13–4 Change the location line to keep the walls from shifting and then change to a different type
Figure 13–5 Defining the space for a stairwell
Within this long thin space, we will add our egress stair.
Now let’s add the stairs.
Figure 13–6 Create a new stair and configure the settings
We’ll accept the remaining defaults for the stair and begin drawing it.
Figure 13–7 Draw the first run of stairs with two clicks
Figure 13–8 Create the second run using up the remaining risers
You will see small numbers labeling the treads at the start and end of each run. You can independently select each run, the landing and all the supports. Each has its own properties and settings on the Properties palette.
If you need to adjust the configuration of the stair, you can click one of the runs, and use the small triangular control handle at the end to make adjustments. As you stretch this grip handle, treads will be shifted between this and the other run. Give it a try if you like. Railings will not appear until you finish the stair.
Figure 13–9 A warning about the inside railing
Sometimes a warning will appear indicating an issue with the railings. In this case, if we adjust the stair runs and/or the landing shape, it should rectify the problem (see Figure 13–9).
This puts us back in stair edit mode.
Notice that the first run will move into alignment with the second one (see Figure 13–10).
Figure 13–10 Use the Align tool to adjust the position of the stair run and adjust the shape of the landing
Notice all the shape handles on each edge. We can use these to adjust the shape of the landing. There is also a temporary dimension for the overall width. Let’s adjust that slightly.
Figure 13–11 Adjust the width of the landing
The railing will adjust to reflect the changes to the stair. To complete the stair, you can add a few more walls and fine-tune its location by simply moving the stair (see Figure 13–12).

It can be nice to study the results in another view as well. You are welcome to create a section, or a cutaway 3D view. Creating one is as simple as making a selection.
This will open the default {3D} view and crop it to the selection. It is a good idea to rename the view to something more descriptive.
