BIMSTAIR command

Automatically creates a BIM staircase.

BricsCAD BIM

Icon:

Description

Creates stairs between two floor slabs or any empty spaces using the distance between the Z- values of the selected start plane and end plane as the height.

Method

You can start creating a staircase by:

  • Selecting a horizontal face of a solid.
  • Selecting a void area.

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.

The staircase is created as a parametric block with BIM properties. The component type is BIM Block(for more information about BIM Blocks, see the Using the Library panel article).

Important: BIM Blocks are compatible with BricsCAD® V26 and later. Drawings with BIM Blocks can be opened with older BricsCAD® versions. However, when inserting BIM Blocks in BricsCAD® V25 or older, they lose their BIM data.

For all properties, parameters are created when creating the stair, driving the constraints of the parametric block. You can change these parameters individually afterward in the Parameters section of the Properties panel.

The Stair command panel opens, which allows you to easily change the settings before or while placing the staircase.

Stair width
Sets the stair width of the stairs.
The default value is 40 for MEASUREMENT=0 (inches), and 1000 for MEASUREMENT=1 (millimeters).
Head room
Sets the minimal head clearance of the stairs.

The default value is 80 for MEASUREMENT=0 (inches), and 2000 for MEASUREMENT=1 (millimeters).

Automatically flip/quarter-turn
Toggles the stairs type.
Preferred tread length
Sets the preferred tread length of the stairs.
The default value is 11.5 for MEASUREMENT=0 (inches), and 290 for MEASUREMENT=1 (millimeters).
Preferred riser height
Sets the preferred riser height of the stairs.
The default value is 7 for MEASUREMENT=0 (inches), and 170 for MEASUREMENT=1 (millimeters).
Step thickness
Sets the thickness of the individual steps.
The default value is 2 for MEASUREMENT=0 (inches), and 50 for MEASUREMENT=1 (millimeters).
Nosing
Sets the horizontal distance of the overlap between subsequent treads.
The default value is 2 for MEASUREMENT=0 (inches), and 50 for MEASUREMENT=1 (millimeters).
Final tread
Controls the creation of a tread at the elevation of the top bounding slab.
Final tread length
Sets the length of the final tread.

The default value is 11.5 for MEASUREMENT=0 (inches), and 290 for MEASUREMENT=1 (millimeters).

Landing extension up
Sets the extension of the landings created with the BIMSTAIR command in the up direction. Default value is 0.
Landing extension down
Sets the extension of the landings created with the BIMSTAIR command in the down direction. The default value is 0.
Note: The last value for the above settings are remembered.

Options within the command

Quarter-turn
Turns the direction of the stair cursor by 90 degrees.
Note: Alternatively, you can press the Ctrl key once to turn the stair cursor by 90 degrees.
Flip
Turns the direction of the stair cursor by 180 degrees.
Note: Alternatively, you can press the Ctrl key twice to turn the stair cursor by 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 the Ctrl key to switch between the possible stair types with respect to the current position of the stair cursor.
  • To use the Ctrl key functions, the HOTKEYASSISTENT system variable must be set to On.
