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.

Options

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.

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.

Limitations

Skript

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)
