Arch Stairs/ru

Описание
Инструмент лестницы позволяет автоматически создавать несколько типов лестниц. В настоящий момент поддерживаются только прямые лестницы (с или без центральной посадки). Лестница может быть построена с нуля или с прямой line, и в этом случае лестница следует за строкой. Если линия не горизонтальна, а имеет вертикальный наклон, лестница также будет следовать ее наклону.

См. [Http://en.wikipedia.org/wiki/Stairs Stairs entry in wikipedia] для определения различных терминов, используемых для описания частей лестницы.

«На вышеупомянутом изображении были созданы две лестницы, одна с массивной структурой и посадкой, а другая с одним стрингером».

 * 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.

Data

 * : (read-only) The absolute top level the stairs lead to.
 * : 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.
 * : The left outline of the stairs.
 * : The left outline of all segments of the stairs.
 * : The right outline of the stairs.
 * : The right outline of all segments of the stairs.
 * : Height of the left railing of the stairs or landing.
 * : Height of the right railing of the stairs or landing.
 * : Name of the left railing object.
 * : Offset of the left railing from the edge of the stairs or landing.
 * : Offset of the right railing from the edge of the stairs or landing.
 * : Name of the right railing object.


 * : The alignment of the stairs on the baseline. Only used if a baseline is defined. Can be, or.
 * : The total height of the stairs. Only used if no baseline is defined, or if the baseline is horizontal. Ignored if is non-zero.
 * : The total length of the stairs if no baseline is defined. Ignored if is non-zero.
 * : The width of the stairs.
 * : If the is 1, the stairs object acts as a landing. When this is the case and the baseline is multi-segment, the width of first segment of the landing follows the, the widths of subsequent segments follow the list set here.


 * : (read-only) The calculated Blondel ratio. This ratio indicates comfortable stairs and should be between 62 and 64cm or 24.5 and 25.5in.
 * : The depth of the landing of the flight, if enabled in . Defaults to the if 0.
 * : The size of the nosing.
 * : The numbers of steps (risers).
 * : (read-only) The height of the risers. If is 0 it is calculated ( / ). Else it is the same as.
 * : The enforced height of the risers.
 * : The thickness of the risers.
 * : (read-only) The depth of the treads. If is 0 it is calculated ( / ). Else it is the same as.
 * : The enforced depth of the treads.
 * : The thickness of the treads.


 * : The type of connection between the lower floor slab and the start of the stairs. Can be, or.
 * : The type of connection between the end of the stairs and the upper floor slab. Can be or.
 * : The thickness of the lower floor slab.
 * : The direction of the flight after the landing. Can be, or.
 * : The type of landings. Can be or  ( not implemented yet).
 * : The overlap of the stringers above the bottom of the treads.
 * : The width of the stringers.
 * : The structure type of the stairs. Can be, , or.
 * : The offset between the border of the stairs and the structure.
 * : The thickness of the structure.
 * : The thickness of the upper floor slab.
 * : The type of winders. Not implemented.
