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|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. |

Description
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 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.
Options
- Stairs share the common properties and behaviors of all Arch Components
Usage
- Press the Arch Stairs button, or press S, R 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.
Properties
Data
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.
Stairs
- DANEAlign (
Enumeration
): The alignment of the stairs on the baseline. Only used if a baseline is defined. Can beLeft
,Right
orCenter
. - 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.
Steps
- 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.
Structure

Enumeration
): The type of connection between the lower floor slab and the start of the stairs. Can beHorizontalCut
,VerticalCut
orHorizontalVerticalCut

ortoSlabThickness
. - DANEDown Slab Thickness (
Length
): The thickness of the lower floor slab. - DANEFlight (
Enumeration
): The direction of the flight after the landing. Can beStraight
,HalfTurnLeft
orHalfTurnRight
. - DANELandings (
Enumeration
): The type of landings. Can beNone
orAt center
(At each corner
not 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 beNone

,One stringer
orTwo stringers
. - 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.
Limitations
- Only straight stairs are available at the moment
- See the forum entry for circle stairs.
- See the forum announcement.
Scripting
See also: Arch API and FreeCAD Scripting Basics.
The Stairs tool can be used in macros and from the Python console by using the following function:
Stairs = makeStairs(baseobj=None, length=None, width=None, height=None, steps=None, name="Stairs")
- Creates a
Stairs
object from the givenbaseobj
. - If
baseobj
is not given, it will uselength
,width
,height
, andsteps
, to build a solid object.
Example:
import Arch
Stairs = Arch.makeStairs(length=5000, width=1200, height=3000, steps=14)
