Arch

Description

See the Stairs entry in wikipedia for a definition of the different terms used to describe parts of stairs.

Options

Usage

Complex stairs based on a selection of lines and wired as shown on the left.
In red the wires used for the landings at Z=1500mm, Z=3000mm and Z=4500mm.
In black the lines connecting them used for the flights.

Vlastnosti

An Arch Stairs object shares the common properties and behaviors of all Arch Components.

Data

Segment and Parts

• ÚdajeAbs Top (Vector): (read-only) The absolute top level the stairs lead to.
• ÚdajeLast 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.
• ÚdajeOutline Left (VectorList): The left outline of the stairs (read-only).
• ÚdajeOutline Left All (VectorList): The left outline of all segments of the stairs (read-only).
• ÚdajeOutline Right (VectorList): The right outline of the stairs (read-only).
• ÚdajeOutline Right All (VectorList): The right outline of all segments of the stairs (read-only).
• ÚdajeRailing Height Left (Length): Height of the left railing of the stairs or landing.
• ÚdajeRailing Height Right (Length): Height of the right railing of the stairs or landing.
• ÚdajeRailing Left (LinkHidden): The left railing object. introduced in 0.20: Property type updated from String to LinkHidden.
• ÚdajeRailing Offset Left (Length): Offset of the left railing from the edge of the stairs or landing.
• ÚdajeRailing Offset Right (Length): Offset of the right railing from the edge of the stairs or landing.
• ÚdajeRailing Right (LinkHidden): The right railing object. introduced in 0.20: Property type updated from String to LinkHidden.

Stairs

• ÚdajeAlign (Enumeration): The alignment of the stairs on the baseline. Only used if a baseline is defined. Can be Left, Right or Center.
• ÚdajeHeight (Length): The total height of the stairs. Only used if no baseline is defined, or if the baseline is horizontal. Ignored if ÚdajeRiser Height Enforce is non-zero.
• ÚdajeLength (Length): The total length of the stairs if no baseline is defined. Ignored if ÚdajeTread Depth Enforce is non-zero.
• ÚdajeWidth (Length): The width of the stairs.
• ÚdajeWidth of Landing (FloatList): If the ÚdajeNumber 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 the first segment of the landing follows the ÚdajeWidth, and the widths of subsequent segments follow the list set here.

Steps

• ÚdajeBlondel 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.
• ÚdajeLanding Depth (Length): The depth of the landing of the flight, if enabled in ÚdajeLandings. Defaults to the ÚdajeWidth if 0.
• ÚdajeNosing (Length): The size of the nosing.
• ÚdajeNumber Of Steps (Integer): The numbers of steps (risers). Must be at least 2 for a single flight, and at least 4 for stairs with a central landing.
• ÚdajeRiser Height (Length): (read-only) The height of the risers. If ÚdajeRiser Height Enforce is 0 it is calculated (ÚdajeHeight / ÚdajeNumber of Steps). Else it is the same as ÚdajeRiser Height Enforce.
• ÚdajeRiser Height Enforce (Length): The enforced height of the risers.
• ÚdajeRiser Thickness (Length): The thickness of the risers.
• ÚdajeTread Depth (Length): (read-only) The depth of the treads. If ÚdajeTread Depth Enforce is 0 it is calculated (ÚdajeLength / ÚdajeNumber of Steps). Else it is the same as ÚdajeTread Depth Enforce.
• ÚdajeTread Depth Enforce (Length): The enforced depth of the treads.
• ÚdajeTread Thickness (Length): The thickness of the treads.

Structure

• ÚdajeConnection Down Start Stairs (Enumeration): The type of connection between the lower floor slab and the start of the stairs. Can be HorizontalCut, VerticalCut or HorizontalVerticalCut.
• ÚdajeConnection End Stairs Up (Enumeration): The type of connection between the end of the stairs and the upper floor slab. Can be toFlightThickness or toSlabThickness.
• ÚdajeDown Slab Thickness (Length): The thickness of the lower floor slab.
• ÚdajeFlight (Enumeration): The direction of the flight after the landing. Can be Straight, HalfTurnLeft or HalfTurnRight. The ÚdajeLandings property must be set to At center.
• ÚdajeLandings (Enumeration): The type of landings. Can be None or At center (At each corner not implemented yet).
• ÚdajeStringer Overlap (Length): The overlap of the stringers above the bottom of the treads.
• ÚdajeStringer Width (Length): The width of the stringers.
• ÚdajeStructure (Enumeration): The structure type of the stairs. Can be None, Massive, One stringer or Two stringers. For the last two options, the ÚdajeStringer Width and ÚdajeTread Thickness properties must have non-zero values.
• ÚdajeStructure Offset (Length): The offset between the border of the stairs and the structure.
• ÚdajeStructure Thickness (Length): The thickness of the structure.
• ÚdajeUp Slab Thickness (Length): The thickness of the upper floor slab.
• ÚdajeWinders (Enumeration): The type of winders. Not implemented.

Limitations

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 given baseobj.
• If baseobj is not given, it will use length, width, height, and steps, to build a solid object.

Example:

import Arch

Stairs = Arch.makeStairs(length=5000, width=1200, height=3000, steps=14)
