Description
The Arch Stairs tool allows you to build several types of stairs automatically. Straight stairs (with or without a central landing) can be created from scratch. More complex stairs require base objects.
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, the other with a single stringer.
Opções
- Stairs share the common properties and behaviors of all Arch Components
Usage
- Optionally select one or more base objects, for example Draft Lines and Draft Wires:
- Draft Wires with two or more segments will be used to create landings. They must be on a plane parallel to the global XY plane. For example, select a U-shaped wire for a half-turn landing and an L-shaped wire for a corner landing.
- Draft Lines will be used to create flights.
- If the vertices of all lines and wires have correct Z coordinates, the created stairs will use this information.
- The base objects must be selected in the correct order starting with the bottom object.
- Press the 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.
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.
Propriedades
Data
Segment and Parts
- DadosAbs Top (
Vector
): (read-only) The absolute top level the stairs lead to. - DadosLast 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. - DadosOutline Left (
VectorList
): The left outline of the stairs. - DadosOutline Left All (
VectorList
): The left outline of all segments of the stairs. - DadosOutline Right (
VectorList
): The right outline of the stairs. - DadosOutline Right All (
VectorList
): The right outline of all segments of the stairs. - DadosRailing Height Left (
Length
): Height of the left railing of the stairs or landing. - DadosRailing Height Right (
Length
): Height of the right railing of the stairs or landing. - DadosRailing Left (
LinkHidden
): The left railing object. introduced in version 0.20: Property type updated fromString
toLinkHidden
. - DadosRailing Offset Left (
Length
): Offset of the left railing from the edge of the stairs or landing. - DadosRailing Offset Right (
Length
): Offset of the right railing from the edge of the stairs or landing. - DadosRailing Right (
LinkHidden
): The right railing object. introduced in version 0.20: Property type updated fromString
toLinkHidden
.
Stairs
- DadosAlign (
Enumeration
): The alignment of the stairs on the baseline. Only used if a baseline is defined. Can beLeft
,Right
orCenter
. - DadosHeight (
Length
): The total height of the stairs. Only used if no baseline is defined, or if the baseline is horizontal. Ignored if DadosRiser Height Enforce is non-zero. - DadosLength (
Length
): The total length of the stairs if no baseline is defined. Ignored if DadosTread Depth Enforce is non-zero. - DadosWidth (
Length
): The width of the stairs. - DadosWidth of Landing (
FloatList
): If the DadosNumber 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 DadosWidth, the widths of subsequent segments follow the list set here.
Steps
- DadosBlondel 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. - DadosLanding Depth (
Length
): The depth of the landing of the flight, if enabled in DadosLandings. Defaults to the DadosWidth if 0. - DadosNosing (
Length
): The size of the nosing. - DadosNumber Of Steps (
Integer
): The numbers of steps (risers). Must be at least 2 for a single flight, and at least 4 for a stairs with a central landing. - DadosRiser Height (
Length
): (read-only) The height of the risers. If DadosRiser Height Enforce is 0 it is calculated (DadosHeight / DadosNumber of Steps). Else it is the same as DadosRiser Height Enforce. - DadosRiser Height Enforce (
Length
): The enforced height of the risers. - DadosRiser Thickness (
Length
): The thickness of the risers. - DadosTread Depth (
Length
): (read-only) The depth of the treads. If DadosTread Depth Enforce is 0 it is calculated (DadosLength / DadosNumber of Steps). Else it is the same as DadosTread Depth Enforce. - DadosTread Depth Enforce (
Length
): The enforced depth of the treads. - DadosTread Thickness (
Length
): The thickness of the treads.
Structure
- DadosConnection Down Start Stairs (
Enumeration
): The type of connection between the lower floor slab and the start of the stairs. Can beHorizontalCut
,VerticalCut
orHorizontalVerticalCut
. - DadosConnection End Stairs Up (
Enumeration
): The type of connection between the end of the stairs and the upper floor slab. Can betoFlightThickness
ortoSlabThickness
. - DadosDown Slab Thickness (
Length
): The thickness of the lower floor slab. - DadosFlight (
Enumeration
): The direction of the flight after the landing. Can beStraight
,HalfTurnLeft
orHalfTurnRight
. - DadosLandings (
Enumeration
): The type of landings. Can beNone
orAt center
(At each corner
not implemented yet). - DadosStringer Overlap (
Length
): The overlap of the stringers above the bottom of the treads. - DadosStringer Width (
Length
): The width of the stringers. - DadosStructure (
Enumeration
): The structure type of the stairs. Can beNone
,Massive
,One stringer
orTwo stringers
. - DadosStructure Offset (
Length
): The offset between the border of the stairs and the structure. - DadosStructure Thickness (
Length
): The thickness of the structure. - DadosUp Slab Thickness (
Length
): The thickness of the upper floor slab. - DadosWinders (
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)
