ANSWER

A floating staircase can easily be created by customizing the stringer, tread, and railing settings associated with a staircase. 


To create a floating staircase

  1. In your desired plan, navigate to Build> Stairs , select your desired Stair  tool, then create the staircase that will be a floating staircase. 


  2. With the staircase created, Select  it, then click the Open Object  edit tool. 


  3. In the Staircase Specification dialog that displays: 

    Style panel of the Interior Staircase Specification dialog

    • On the Style panel, specify your desired Tread Overhang and Tread Thickness, then ensure that the Open Risers and Open Underneath boxes are both checked. 

      In this example, the Tread Thickness is changed from the default value of 1" to 3". 

    • On the Stringers panel, specify your desired Stringer Style, as well as other settings such as the wall trim and stringer options. 

      In this example, the 1 Center Stringer option is selected. However, you can choose No Stringers to remove all stringers from the staircase, or Custom Stringers to specify a fully custom stringer configuration. 

    • Access the Railing, Newels/Balusters, and Rails panels to adjust properties associated with the stair railings.


  4. Make any other desired modifications to your staircase, then click OK


  5. Take a Camera  view to see the results.
