All

View

Determines the view to apply the parameters to the stair; depending on drawing settings like layer scale and the document preference Hide details, the detailed or schematic view status is displayed

All

Detailed

Applies the construction parameters to stairs in a detailed layer scale view

All

Schematic

Applies the construction parameters to stairs in a schematic scaled view

All

Accept for all Views

Applies the construction parameters to stairs in all views (detailed and schematic)

All

Construction Configuration

Select the type of construction for the stair

All

Solid Stair

Models the stair structure as single, monolithic geometry, but still includes treads and risers

All

Stringer Underneath

Models the stair structure as one, two, or three stringers (carriages) underneath that support the treads and risers above them. If three stringers are specified, the third will automatically be centered between the others, not the edge of the steps.

All

Stringer Outside

Models the stair structure as two stringers (carriages) on either side of the stair which support the treads and risers above them

All

Concrete Stair

Models the stair structure as monolithic, without separate treads or risers

All

Circular Stair

For circular stair configurations, select to obtain circular stair construction parameters

All

Construction Settings

All

Upper Floor Thickness

Wraps the 3D stair geometry at the top of the stair around the edge of the floor slab by the indicated distance, correctly terminating all parts related to the construction type

All

Lower Floor Thickness

Wraps the 3D stair geometry at the bottom of the stair around the edge of the floor slab by the indicated distance, correctly terminating all parts related to the construction type. If set to 0 (zero) truncates the stair geometry so the bottom of the stair rests on top of the slab

All

Landing Thickness

Specifies the thickness of the stair landing, excluding any treads. The landing thickness plus the tread thickness is equal to the distance from the top of the tread to the bottom of the landing (solid stairs) or stringer (stringer underneath)

Stairs with a single landing

Landing Thickness 1

Specifies the thickness of the first stair landing, excluding any treads

Stairs with two landings

Landing Thickness 2

Specifies the thickness of the second stair landing, excluding any treads

Stairs with two landings

Solid Structure Thickness

When selected, draws 3D geometry below the treads and risers representing the structural mass of the stair. Specify the distance from the rear face to the inside edge where the riser and tread meet.

Solid
Concrete

Tread Thickness

When selected, draws 3D stair tread geometry; specify the tread thickness

Solid
Stringer Underneath
Stringer Outside

Riser Thickness

When selected, draws 3D stair riser geometry; specify the riser thickness

Solid
Stringer Underneath
Stringer Outside

Nosing/Riser Offset

When selected, draws both 2D and 3D stair nosing geometry; set the distance that the nosing extends past the riser face over the preceding tread

All

Create Top Riser and Nosing

For stairs with the Draw Top Tread option disabled on the Geometry tab, select whether to display the top riser and tread nosing in 3D views

All

Offset Right (or Inner Offset)

Offsets the stair body from the right/inner edge of the stair treads and riser by the distance specified; as determined by the stair width, configuration, and orientation

Solid
Stringer Underneath

Offset Left (or Outer Offset)

Offsets the stair body from the left/outer edge of the stair treads and riser by the distance specified; as determined by the stair width, configuration, and orientation

Solid
Stringer Underneath

Stringer Depth

Sets the stringer’s structural clear depth

Stringer Underneath
Stringer Outside

Stringer Width

Sets the thickness (width) of the stringer

Stringer Underneath
Stringer Outside

Stringer Distance

For stairs with one stringer, specifies the stringer’s offset distance from the center of the stair

Stringer Underneath

Tread/Stringer Offset

Sets the tread’s offset distance from the bottom of the stringer’s depth, as measured to the back, bottom edge of the tread

Stringer Outside

Stringer Extension at Stair Bottom

Specifies the distance that the stringer extends past the front edge of the starting (bottom) tread

Stringer Outside

Stringer Extension at Stair Top

Specifies the distance that the stringer extends past the front edge of the last (top) tread

Stringer Outside

Column

When selected, adds a central column

All, when stair configuration is Circular Stair

Custom Column Height

Specifies the central column height for spiral stairs

All, when stair configuration is Circular Stair

Custom Column Diameter

Specifies the central column diameter for spiral stairs

All, when stair configuration is Circular Stair

Outside Nosing

Sets the value for the tread nosing at the outside diameter of a circular stair

Circular stair, when stair configuration is also circular stair
