Description

The 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.

On the above image, two stairs were created, one with a massive structure and a landing, and another one with a single stringer.

Options

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

How to use

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.

Properties

Base

• DATAAlign: The alignment of these stairs on their baseline, if applicable.
• DATABase: The baseline of these stairs, if any.
• DATAHeight: The total height of these stairs, if not based on a baseline, or the baseline is horizontal.
• DATALength: The total length of these stairs if no baseline is defined.
• DATAWidth: The width of these stairs.

Steps

• DATANosing: The size of the nosing.
• DATANumber of Steps: The numbers of steps (risers) in these stairs.
• DATARiser Height: The height of the risers.
• DATATread Depth: The depth of the treads.
• DATATread Thickness: The thickness of the treads.

Structure

• DATALandings: The type of landings.
• DATAStringer Offset: The offset between the border of the stairs and the structure.
• DATAStringer Width: The width of the stringers.
• DATAStructure: The type of structure of these stairs.
• DATAStructure Thickness: The thickness of the structure.
• DATAWinders: The type of winders.

Skript

Stairs can be created from python scripts and macros by using the following function:

makeStairs([base], [length], [width], [height], [steps]) 

• Creates a stairs object with the given attributes.
• Returns the new stairs object.

Example:

import Arch
makeStairs(length=5, width=1.2, height=3, steps=14) 

Limitations

• Not available before FreeCAD version 0.14
• Only straight stairs are available at the moment
• See the forum entry for circle stairs.
• See the forum announcement.
