There is a separate Stairs Extension that contains tools for drawing stairs, landings, and railings of different sorts. Downloading and installing this Extension will add two separate component tabs to CET: Commercial Stairs with components suitable for office and home environments, and Industrial Stairs with stairs for industry and storage sectors.

How to Insert Stairs
To simply place the stairs, a single click upon inserting the Stairs would place the default dimensions of the Stairs.
While inserting the stairs, you can also hold left-click and:
- drag up/down the stairs would alter the total run for the top/bottom side of the stairs.
- rotate (move the mouse to the side of the stairs) would insert the default Stairs dimensions but with the ability to rotate.
The 'blue riser' at the top of the Stairs indicates where the Landings can be placed. Besides that, it can also act as a guideline when connecting it to another level/floor.
Multiple stairs can be attached to the same side of a landing with 2 clicks. The 1st is to snap the stairs to the landing while the 2nd click is to confirm placement after specifying the direction of the stairs in the Quick Property box.
Railings are automatically added to Industrial Stairs that follow building codes while 'Custom' stairs are placed without railings.
Properties
You can alter the dimensions in the Quick Property box during and after inserting the Stairs. You will get more options after inserting the Stair.

Directions on how to attach the stairs would be helpful. Where does the translucent blue riser position? How would you calculate the rise. It would be nice if you could attached and positioned the stairs at the bottom and then drag up like an accordion and then snap to the next level.
Hi Amy, sorry for the delay, we do agree that this article was indeed lacking of directions.
Thus, we have now updated this article to include answering your questions.
Do take a look back if you feel if anything else is missing.
It would be nice to assign stairs to a level or change their starting elevation. Am I missing the location of this feature?
Hi,
You may assign the stairs to the desired level through the Categorization tool, and it will be registered to the checked level.
More info on that here: Categorization Dialog: Levels Tab – Configura Help Center
