Creates stairs.

Description

Creates stairs between 2 floor slabs or any empty space and it will create a stair. This command is using the default floor-to-floor-distance as height.

The stairs display automatically when the cursor is moved. The type of stair being created depends on the position of the cursor with respect to the position of the selected start point.

Note: The staircase is created as a parametric block. The Stair Type is assigned automatically and can be edited in the Properties panel. Editing this property does not affect the geometry of the staircase.

Methods

There are two methods to create stairs using the BIMSTAIR command:

  • Select a horizontal face of a solid.
    Note: If both the start plane and the end plane of a stair are horizontal faces of a solid, the stair height is set to the difference between Z-values of start plane and the end plane.
  • Select a void area.
    Note: If the start plane of a stair is a horizontal face of a solid and the end plane is a void area, the stair height is set to the difference between Z-values of start plane and the end plane. If the start plane is also a void area, then the stair height is set to the current value of the FLOORTOFLOORDISTANCE system variable.

Options

Quarter-turn
Turns the direction of the stair cursor with 90 degrees.
Note: Press Ctrl key to turn the stair cursor with 90 degrees.
Flip
Turns the direction of the stair cursor with 180 degrees.
Note: Press Ctrl key to turn the stair cursor with 180 degrees.
U-shape type
Switches between two different U-shape type stairs:
  • • Double-flight U-shaped stairs (1): with a single rectangular landing solid bridging the perpendicular distance between both opposing stair flights.
  • • Triple-flight U-shaped stairs (2): with two square landing solids between each pair of subsequent stair flights.
Note: Press Ctrl key to cycle the possible stair types with respect to the current position of the stair cursor.
Note: The HOTKEYASSISTENT must be set ON to use Ctrl key functions.
Stair settings
Opens the Settings dialog box, where the parameters of the stair can be set.
  • Stair width:Default width of the stairs
  • Preferred tread length: Preferred tread length of the stairs
  • Ideal riser height: Ideal riser height of the stairs
  • Head room: Sets the minimum clearance for the opening to be created
  • Step thickness: Thickness of the individual steps
  • Nosing: Horizontal distance of overlap between subsequent treads
  • Final tread length: Length of the final tread, this always in regard to the top tread of the stair
  • Automatically flip/quarter-turn: Turn on if you want to automatically flip or turn when you hover over the slab with your cursor and snap the blue StairCursor to the walls (the end of the arrow can then never be facing a wall)
  • Final tread: Controls creation of a tread at the elevation of the top bounding slab.
Note: For all properties, parameters will be created when creating the stair, driving the constraints of the parametric stair block. These parameters can be then changed individually afterward in the Parameters section of the Properties panel.
