How do I create a set of winder stairs?

Custom Stair Winders in L-shaped stairs


Stair winders can be created using a variety of different methods, which include:

To create stair winders using the Stair Specification dialog

Winders created using the Stair Specification dialog must be created in a room with proper room definition. 

You cannot create winders using this method in an area composed of only 2 corner walls. If this configuration is needed, enclose the area in with invisible walls so that a room area is defined. 

  1. First, make sure that the correct editing behaviors and snap settings are used:  

    • Select Edit> Edit Behaviors  from the menu and confirm that Connect CAD Segments  is turned on. If you see a check next to this menu item, it is enabled.

      If you are working in an older version verify that Edit Object Parts  is not enabled.

    • Select Edit> Snap Settings from the menu and confirm that Object Snaps  is enabled. If there is not a check next to this option, select it once to enable it.  

  2. Select Build> Stairs> Draw Stairs , then click and drag to create a section of stairs with the number of treads leading up to the winder section, in this example 7 treads are used.

  3. Next, create a second set of stairs with the bottom of the first tread snapping to the top of the last tread of the section created in step 2. Draw the number of treads to be the Winder section.

    • In this example, 4 treads are used. 

  4. Press the Space Bar to return to the Select Objects  tool. Click once on the winder section of stairs to select them.  

    Both stair sections are selected

  5. Press and hold the Alt key if you're on a Windows machine, or the Control key if you're on a Mac, then click and drag the edit handle at the top of the Winder stair section in the direction you want. 

    Alternatively, Right click and drag will enable this alternate drawing mode as well.

    Curving the second stair section

    This allows you to change the second straight segment into a curved one.  

  6. Next, using the Draw Stairs tool, attach a section of stairs to the end of the Winder where the stairs stop to finish the staircase.

    Your staircase should now look similar to the image above.  

  7. Move the staircase into the corner you want it placed, and then select the Open Object  edit button. 

  8. In the Staircase Specification dialog that opens, place a check in the Winders box on the right, then click OK.  

    Check the Winders box on the General panel of the Staircase Specification dialog

  9. Winders will now be created and will extend into the corner as shown in the image below.

    • Adjust the Top Height.

      If Auto Adjust Height is selected, and the landing is bumped up against the top of a stair or another landing, the landings Top Height will automatically adjust to that component.
