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.

Opções

• Stairs share the common properties and behaviours of all Arch Components

Usage

1. Press the 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.

Propriedades

Base

• DadosAlign: The alignment of these stairs on their baseline, if applicable.
• DadosBase: The baseline of these stairs, if any.
• DadosHeight: The total height of these stairs, if not based on a baseline, or the baseline is horizontal.
• DadosLength: The total length of these stairs if no baseline is defined.
• DadosWidth: The width of these stairs.

Steps

• DadosNosing: The size of the nosing.
• DadosNumber of Steps: The numbers of steps (risers) in these stairs.
• DadosRiser Height: The height of the risers.
• DadosTread Depth: The depth of the treads.
• DadosTread Thickness: The thickness of the treads.

Structure

• DadosLandings: The type of landings.
• DadosStringer Offset: The offset between the border of the stairs and the structure.
• DadosStringer Width: The width of the stringers.
• DadosStructure: The type of structure of these stairs.
• DadosStructure Thickness: The thickness of the structure.
• DadosWinders: The type of winders.

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 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)
