A typical stair consist of Runs, Landing, Supports and Railing. These elements can be independently controlled as well as are connected with each other. For example, if you remove the staircase, railing on the stairs will automatically be deleted. You can model stairs assembling Run Component or by sketching them.

Stair by Run Component

Step by Step guide to creating stairs using Run Component:

Select the Run Component Tool and Specify Options
Create a Straight Run

Stair by Sketching Components

If you would like to create a custom design for the staircase, you may opt for sketching mode where you can sketch stair components to create the overall assembly.

Step by Step guide to creating stairs by sketching:

Create a Stair Run by Sketching
Modify a Sketched Stair
Create a Landing Component by Sketching
Modify Stair Railings
Define a Zero Tread Thickness for Monolithic Stairs
Convert a Stair Component to a Sketch

Multistory Stair

Multistory stair is a great tool to extend your staircase to multiple building levels. If the level heights change, the staircase would also adjust automatically, adding a lot of productivity to your workflow.

About Stairs

A typical stair consist of the following elements:

Runs: straight, spiral, U-shaped, L-shaped, custom sketched run
Landings: created automatically between runs or by picking 2 runs, or by creating a custom sketched landing
Supports (side and center): created automatically with the runs or by picking a run or landing edge
Railings: automatically generated during creation or placed later

These elements can independently controlled as well as are connected with each other. For example, if you remove the staircase, railing on the stairs will automatically be deleted.

Sample Problem:

Create a U-shaped monolithic (concrete) staircase in the sample project between "00 Ground Level" to "01 First Floor level" as shown below:

Solution:

Although, Revit provides great tools to automatically calculate number of risers needed for a stair between two selected levels, it makes it easier if you are clear about what kind of stair do you really want for your design. Some planning and preparation goes a long way in making a perfect stair! I recommend that before you begin adding a stair in your project, use "Detail Lines" to sketch out the basic shape of your stair, number of risers you would like to have on each run, overall width of your stair, tread depth and the total height of the stair (between levels/other).

The tutorial file "TutorialStairs_Input_LearningRevitOnline.rvt" already contains the sketch of the stairs using Detail Lines for your reference. Open this file in Revit.
Navigate to the floor plan of "00 Ground Level". Notice the detail lines marking the basic sketch of the stair.
Now, let's create a U-shaped monolithic stair (RCC/Concrete stair) between Ground Level and First Floor Level by sketching Run component.
To add a stair using Run Component:
- Click Architecture tab -> Circulation panel -> Stair
- On the Component panel, verify that Run is selected.
- On the Options Bar, For Location Line, choose the Run:Center
- On the Options Bar, add Actual Run width as "1.2m".
- Now, in the Type selector, choose Cast-In-Place monolithic stair.
- Select the Base level of the stair as "00 Ground Level" and Top level of the stair as "01 First Floor level".
- Add desired number of risers as 18 and actual tread depth as 0.28m
- Notice that when you change the 'Desired number of Risers', the actual riser height is calculated automatically by dividing the total stair height/desired number of risers. If this value exceeds the maximum riser height specified in the type properties, Revit will give an error. Set up your calculation rules in the type properties for maximum riser height and minimum tread depth to prevent the stair risers to be too high and treads to be too narrow while drawing the stair.
- Go to the Type properties of the stairs and additionally, set up the Run Type and Landing Type as per your design requirements.
- Now, in the drawing area, click to enter the start point of the Run. Choose the starting point as the midpoint of the detail line already sketched, as shown below.
- Move straight downwards to select the endpoint of this first Run as shown below. Notice that as you move your cursor downwards, total number of risers created and remaining are displayed in halftone for your reference.
- The first Run with 9 risers is now created.
- Do not worry about the landing at this moment. Continue to draw the second Run by clicking on the starting and ending point as shown below:
- Both Runs are now created and Revit will display that 18 risers are created and 0 are remaining. Notice that the landing has been created automatically by Revit between two Runs. Width of the landing will be the same as the width of the Run.
  - NOTE:If you would like to change the shape/size of the run/landing, you will have to convert the element to sketch mode and then edit the sketch. Learn more about modifying components in a stair, in this video tutorial.
- Click on one of the Runs to select it. In the properties palette, note the parameters begins with riser and ends with riser. Make sure both check boxes are on for both runs. We will discuss about these parameters further in Step 7.
- Click on Finish Edit Mode to complete the stairs.
- The stairs is now added. Notice the annotations of the staircase that have been added automatically by Revit.
- The railing on both sides of the Run and landing has been added automatically. You can select the railing individually and remove it or change its type from the type selector.
Now, you may delete all the detail lines that you initially created for reference.
- TIP:To quickly select all the lines, select all elements in that particular region and then filter selection for the Detail lines.
Create a section line to see the stairs in a Section view.
Begin with riser and End with riser:
- Notice that as we had selected "Begin with riser and end with riser" parameters for both runs, the stairs is sketched accordingly. It is clearer to notice this in a section view. A small gap that you notice between the last riser and the top level, is for the tread thickness.
Go to a 3D view to see the stairs in 3D. Notice that an opening is required in the floor slab for the stairs.
To create an opening in the floor slab:
