Arch Stairs

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

  • Align: The alignment of these stairs on their baseline, if applicable.

  • Base: The baseline of these stairs, if any.

  • Height: The total height of these stairs, if not based on a baseline, or the baseline is horizontal.

  • Length: The total length of these stairs if no baseline is defined.

  • Width: The width of these stairs.

Steps

  • Nosing: The size of the nosing.

  • Number of Steps: The numbers of steps (risers) in these stairs.

  • Riser Height: The height of the risers.

  • Tread Depth: The depth of the treads.

  • Tread Thickness: The thickness of the treads.

Structure

  • Landings: The type of landings.

  • Stringer Offset: The offset between the border of the stairs and the structure.

  • Stringer Width: The width of the stringers.

  • Structure: The type of structure of these stairs.

  • Structure Thickness: The thickness of the structure.

  • Winders: The type of winders.

Limitations

Scripting

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)
