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
- Stairs share the common properties and behaviors of all Arch Components
Usage
- Press the Arch Stairs button, or press S, R keys.
- 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
Data
Segment and Parts
- DataAbs Top (
Vector
): (read-only) The absolute top level the stairs lead to. - DataLast Segment (
Link
): Last segment (flight or landing) of an Arch Stairs connecting to this segment. The start level of the stairs will be the end level of this last segment. - DataOutline Left (
VectorList
): The left outline of the stairs. - DataOutline Left All (
VectorList
): The left outline of all segments of the stairs. - DataOutline Right (
VectorList
): The right outline of the stairs. - DataOutline Right All (
VectorList
): The right outline of all segments of the stairs. - DataRailing Height Left (
Length
): Height of the left railing of the stairs or landing. - DataRailing Height Right (
Length
): Height of the right railing of the stairs or landing. - DataRailing Left (
String
): Name of the left railing object. - DataRailing Offset Left (
Length
): Offset of the left railing from the edge of the stairs or landing. - DataRailing Offset Right (
Length
): Offset of the right railing from the edge of the stairs or landing. - DataRailing Right (
String
): Name of the right railing object.
Stairs
- DataAlign (
Enumeration
): The alignment of these stairs on their baseline, if applicable. - DataHeight (
Length
): The total height of these stairs, if not based on a baseline, or the baseline is horizontal. - DataLength (
Length
): The total length of these stairs if no baseline is defined. - DataWidth (
Length
): The width of these stairs. - DataWidth of Landing (
FloatList
): When Number of Steps = 1, the Stairs object act as a Landing. And when the baseline is multi-segment, the width of each segment of the Landing follow the list set here (for 2nd edge and after - 1st edge follows Width property).
Steps
- DataBlondel Ratio (
Float
): (read-only) The Blondel ratio indicates comfortable stairs and should be between 62 and 64cm or 24.5 and 25.5in. - DataLanding Depth (
Length
): The depth of the landing of the flight, if enabled in Landings. Default to Width of stairs if 0. - DataNosing (
Length
): The size of the nosing. - DataNumber Of Steps (
Integer
): The numbers of steps (risers) in these stairs. - DataRiser Height (
Length
): (read-only) The height of the risers - Height of stairs / Number of Steps or Riser Height Enforce. - DataRiser Height Enforce (
Length
): The height of the risers to enforce (override overall Height of stairs). - DataRiser Thickness (
Length
): The thickness of the risers. - DataTread Depth (
Length
): (read-only) The depth of the treads - Length of stairs / Number of Steps or Tread Depth Enforce. - DataTread Depth Enforce (
Length
): The depth of the treads to enforce (override overall Length of stairs). - DataTread Thickness (
Length
): The thickness of the treads.
Structure
- DataConnection Down Start Stairs (
Enumeration
) - DataConnection End Stairs Up (
Enumeration
) - DataDown Slab Thickness (
Length
) - DataFlight (
Enumeration
): The direction of flight after landing. Can be Straight","HalfTurnLeft",or "HalfTurnRight". - DataLandings (
Enumeration
): The type of landings. Can be "None" or "At center" ("At each corner" not implemented yet). - DataStringer Overlap (
Length
) - DataStringer Width (
Length
): The width of the stringers. - DataStructure (
Enumeration
): The type of structure of these stairs. Can be "None", "Massive", "One stringer" or "Two stringers". - DataStructure Offset (
Length
): The offset between the border of the stairs and the structure. - DataStructure Thickness (
Length
): The thickness of the structure. - DataUp Slab Thickness (
Length
) - DataWinders (
Enumeration
): The type of winders (not implemented).
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 givenbaseobj
. - If
baseobj
is not given, it will uselength
,width
,height
, andsteps
, to build a solid object.
Example:
import Arch
Stairs = Arch.makeStairs(length=5000, width=1200, height=3000, steps=14)
