Opis
Narzędzie Schody umożliwia automatyczne tworzenie kilku rodzajów schodów. Proste schody (z centralnym podestem lub bez) mogą być tworzone od podstaw. Bardziej złożone schody wymagają obiektów bazowych.
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.
Options
- 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 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.
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.
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 (
LinkHidden
): The left railing object. introduced in version 0.20: Property type updated fromString
toLinkHidden
. - 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 (
LinkHidden
): The right railing object. introduced in version 0.20: Property type updated fromString
toLinkHidden
.
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). Must be at least 2 for a single flight, and at least 4 for a stairs with a central landing. - 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
- DANEConnection Down Start Stairs (
Enumeration
): The type of connection between the lower floor slab and the start of the stairs. Can beHorizontalCut
,VerticalCut
orHorizontalVerticalCut
. - DANEConnection End Stairs Up (
Enumeration
): The type of connection between the end of the stairs and the upper floor slab. Can betoFlightThickness
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
,Massive
,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)
