|Arch → Stairs|
|Introduced in version|
|Arch Structure, Arch Equipment|
The Arch Stairs tool allows you to build automatically several types of stairs. At the moment, only straight stairs (with or without a central landing) are supported. Stairs can be built from scratch, or from a straight Draft Line, in which case the stairs follow the line. If the line is not horizontal but has a vertical inclination, the stairs will also follow its slope.
See the Stairs entry in wikipedia for a definition of the different terms used to describe parts of stairs.
Two constructed stairs, one with a massive structure and a landing, and another one with a single stringer.
- Stairs share the common properties and behaviors of all Arch Components
- Press the button, or press , keys.
- Adjust the desired properties. Some parts of the stairs, such as the structure, might not appear immediately, if any of the properties makes it impossible, such as a structure thickness of 0.
Segment and Parts
- DANEAbs Top (
Vector): (read-only) The absolute top level the stairs lead to.
- DANELast Segment (
Link): Last segment (flight or landing) of an Arch Stairs connecting to this segment. The start level of the stairs will be the end level of this last segment.
- DANEOutline Left (
VectorList): The left outline of the stairs.
- DANEOutline Left All (
VectorList): The left outline of all segments of the stairs.
- DANEOutline Right (
VectorList): The right outline of the stairs.
- DANEOutline Right All (
VectorList): The right outline of all segments of the stairs.
- DANERailing Height Left (
Length): Height of the left railing of the stairs or landing.
- DANERailing Height Right (
Length): Height of the right railing of the stairs or landing.
- DANERailing Left (
String): Name of the left railing object.
- DANERailing Offset Left (
Length): Offset of the left railing from the edge of the stairs or landing.
- DANERailing Offset Right (
Length): Offset of the right railing from the edge of the stairs or landing.
- DANERailing Right (
String): Name of the right railing object.
- DANEAlign (
Enumeration): The alignment of the stairs on the baseline. Only used if a baseline is defined. Can be
- DANEHeight (
Length): The total height of the stairs. Only used if no baseline is defined, or if the baseline is horizontal. Ignored if DANERiser Height Enforce is non-zero.
- DANELength (
Length): The total length of the stairs if no baseline is defined. Ignored if DANETread Depth Enforce is non-zero.
- DANEWidth (
Length): The width of the stairs.
- DANEWidth of Landing (
FloatList): If the DANENumber Of Steps is 1, the stairs object acts as a landing. When this is the case and the baseline is multi-segment, the width of first segment of the landing follows the DANEWidth, the widths of subsequent segments follow the list set here.
- DANEBlondel Ratio (
Float): (read-only) The calculated Blondel ratio. This ratio indicates comfortable stairs and should be between 62 and 64cm or 24.5 and 25.5in.
- DANELanding Depth (
Length): The depth of the landing of the flight, if enabled in DANELandings. Defaults to the DANEWidth if 0.
- DANENosing (
Length): The size of the nosing.
- DANENumber Of Steps (
Integer): The numbers of steps (risers).
- DANERiser Height (
Length): (read-only) The height of the risers. If DANERiser Height Enforce is 0 it is calculated (DANEHeight / DANENumber of Steps). Else it is the same as DANERiser Height Enforce.
- DANERiser Height Enforce (
Length): The enforced height of the risers.
- DANERiser Thickness (
Length): The thickness of the risers.
- DANETread Depth (
Length): (read-only) The depth of the treads. If DANETread Depth Enforce is 0 it is calculated (DANELength / DANENumber of Steps). Else it is the same as DANETread Depth Enforce.
- DANETread Depth Enforce (
Length): The enforced depth of the treads.
- DANETread Thickness (
Length): The thickness of the treads.
- DANEConnection Down Start Stairs (
Enumeration): The type of connection between the lower floor slab and the start of the stairs. Can be
- DANEConnection End Stairs Up (
Enumeration): The type of connection between the end of the stairs and the upper floor slab. Can be
- DANEDown Slab Thickness (
Length): The thickness of the lower floor slab.
- DANEFlight (
Enumeration): The direction of the flight after the landing. Can be
- DANELandings (
Enumeration): The type of landings. Can be
At each cornernot implemented yet).
- DANEStringer Overlap (
Length): The overlap of the stringers above the bottom of the treads.
- DANEStringer Width (
Length): The width of the stringers.
- DANEStructure (
Enumeration): The structure type of the stairs. Can be
- DANEStructure Offset (
Length): The offset between the border of the stairs and the structure.
- DANEStructure Thickness (
Length): The thickness of the structure.
- DANEUp Slab Thickness (
Length): The thickness of the upper floor slab.
- DANEWinders (
Enumeration): The type of winders. Not implemented.
- Only straight stairs are available at the moment
- See the forum entry for circle stairs.
- See the forum announcement.
