Winders

Winders are steps located where a staircase turns and are narrower on the inside of the turn than they are on the outside. A staircase defined as a winder expands to fill in any gaps between the side of the stairs and nearby walls. Curved stair sections are typically used to create winders, although straight stairs can also be used.

To create winders

In an enclosed room area, place and connect the stair sections that you want to be winders.

Select any subsection of the stairs and click the Open Object

edit button to open the Staircase Specification dialog.

On the General tab, place a check in the box beside Winder and click OK.

The steps nearest the wall corner adjust their shapes and extend into the corner after the stair is changed to a winder.

Winders must be in a room with valid room definition. You cannot create winders 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.

Tight Winders

Winders cannot be created in a staircase with too tight a curve. The inside edge of the curved treads must be greater than zero. If a staircase curves too tightly, select the winder, click the Make Arc Tangent

edit button, and increase the radius so that it is greater than half of the width of the staircase. See "Editing Arc Based Objects".
