Lo strumento scale consente di creare automaticamente i diversi tipi di scale. Al momento, sono supportate solo le scale dritte (con o senza pianerottolo) sono supportati. Le scale possono essere costruite da zero, o da una linea dritta, nel qual caso le scale seguono la linea. Se la linea non è orizzontale, ma è inclinata verticalmente, anche le scale seguono la sua pendenza.

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

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

• DatiAlign: The alignment of these stairs on their baseline, if applicable.
• DatiBase: The baseline of these stairs, if any.
• DatiHeight: The total height of these stairs, if not based on a baseline, or the baseline is horizontal.
• DatiLength: The total length of these stairs if no baseline is defined.
• DatiWidth: The width of these stairs.

Steps

• DatiNosing: The size of the nosing.
• DatiNumber of Steps: The numbers of steps (risers) in these stairs.
• DatiRiser Height: The height of the risers.
• DatiTread Depth: The depth of the treads.
• DatiTread Thickness: The thickness of the treads.

Structure

• DatiLandings: The type of landings.
• DatiStringer Offset: The offset between the border of the stairs and the structure.
• DatiStringer Width: The width of the stringers.
• DatiStructure: The type of structure of these stairs.
• DatiStructure Thickness: The thickness of the structure.
• DatiWinders: The type of winders.

Scripting

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 announcement.
