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 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.

Arch Stairs example.jpg

Two constructed stairs, one with a massive structure and a landing, and another one with a single stringer.

Options

Usage

  1. Press the Arch Stairs.svg Arch Stairs button, or press S, R keys.
  2. 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

  • ДаніAbs Top (Vector): (read-only) The absolute top level the stairs lead to.
  • ДаніLast 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.
  • ДаніOutline Left (VectorList): The left outline of the stairs.
  • ДаніOutline Left All (VectorList): The left outline of all segments of the stairs.
  • ДаніOutline Right (VectorList): The right outline of the stairs.
  • ДаніOutline Right All (VectorList): The right outline of all segments of the stairs.
  • ДаніRailing Height Left (Length): Height of the left railing of the stairs or landing.
  • ДаніRailing Height Right (Length): Height of the right railing of the stairs or landing.
  • ДаніRailing Left (String): Name of the left railing object.
  • ДаніRailing Offset Left (Length): Offset of the left railing from the edge of the stairs or landing.
  • ДаніRailing Offset Right (Length): Offset of the right railing from the edge of the stairs or landing.
  • ДаніRailing Right (String): Name of the right railing object.

Stairs

  • ДаніAlign (Enumeration): The alignment of the stairs on the baseline. Only used if a baseline is defined. Can be Left, Right or Center.
  • ДаніHeight (Length): The total height of the stairs. Only used if no baseline is defined, or if the baseline is horizontal. Ignored if ДаніRiser Height Enforce is non-zero.
  • ДаніLength (Length): The total length of the stairs if no baseline is defined. Ignored if ДаніTread Depth Enforce is non-zero.
  • ДаніWidth (Length): The width of the stairs.
  • ДаніWidth of Landing (FloatList): If the ДаніNumber 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 ДаніWidth, the widths of subsequent segments follow the list set here.

Steps

  • ДаніBlondel 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.
  • ДаніLanding Depth (Length): The depth of the landing of the flight, if enabled in ДаніLandings. Defaults to the ДаніWidth if 0.
  • ДаніNosing (Length): The size of the nosing.
  • ДаніNumber Of Steps (Integer): The numbers of steps (risers).
  • ДаніRiser Height (Length): (read-only) The height of the risers. If ДаніRiser Height Enforce is 0 it is calculated (ДаніHeight / ДаніNumber of Steps). Else it is the same as ДаніRiser Height Enforce.
  • ДаніRiser Height Enforce (Length): The enforced height of the risers.
  • ДаніRiser Thickness (Length): The thickness of the risers.
  • ДаніTread Depth (Length): (read-only) The depth of the treads. If ДаніTread Depth Enforce is 0 it is calculated (ДаніLength / ДаніNumber of Steps). Else it is the same as ДаніTread Depth Enforce.
  • ДаніTread Depth Enforce (Length): The enforced depth of the treads.
  • ДаніTread Thickness (Length): The thickness of the treads.

Structure

  • ДаніConnection 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.
  • ДаніConnection End Stairs Up (Enumeration): The type of connection between the end of the stairs and the upper floor slab. Can be toFlightThickness or toSlabThickness.
  • ДаніDown Slab Thickness (Length): The thickness of the lower floor slab.
  • ДаніFlight (Enumeration): The direction of the flight after the landing. Can be Straight, HalfTurnLeft or HalfTurnRight.
  • ДаніLandings (Enumeration): The type of landings. Can be None or At center (At each corner not implemented yet).
  • ДаніStringer Overlap (Length): The overlap of the stringers above the bottom of the treads.
  • ДаніStringer Width (Length): The width of the stringers.
  • ДаніStructure (Enumeration): The structure type of the stairs. Can be None, Massive, One stringer or Two stringers.
  • ДаніStructure Offset (Length): The offset between the border of the stairs and the structure.
  • ДаніStructure Thickness (Length): The thickness of the structure.
  • ДаніUp Slab Thickness (Length): The thickness of the upper floor slab.
  • ДаніWinders (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)
