Stair Configuration

The Stair Configuration part of the Create Stair Flight window, with Detail selected, has mostly the same functionality as that available from Layout with the exception of the Pitch Validation functionality.

From the Stair Configuration part of the Create Stair Flight window, you can use the X Offset and Nudge functionality to move the stair flight element along the upper reference edge.

X Offset

If required, you can offset the stair flight with respect to the centreline. Refer to Stair Configuration for further information.

Nudge

Used for positioning the stair flight along the upper reference edge. Refer to Stair Configuration for further information.

Pitch Validation

The Pitch Validation part of the Stair Configuration window, allows you to modify the desired pitch and as a result the number of rises. It also provides the obtained pitch and an overview of the rise, going and validation for each rise.

Validation formulae in the defaults file are selected by the administrator. Refer to Stair Flight for further information.

Desired Pitch

You can modify the desired pitch within the boundaries of the standard. However, you only modify the optimum pitch in the default for the currently selected configuration temporarily. The circle in the list of configurations stays green as long as the SLH application does not alter the pitch.

Select Display to display the Desired Pitch in the 3D view.

Note:
All the pitches within the boundaries set in the default are available for selection. The SLH application may not be able to build a stair with the selected pitch if the reference edge positions are too close.

Obtained Pitch

The Obtained Pitch field within the Pitch Validation part of the Stair Configuration window, displays the pitch that is obtained for the currently selected configuration.

You can, if required, select another number of rises (as long as they are available for selection), modifying the number of the rises impacts the pitch, rise, going and validation.

Modifying one value may alter others as well. Changing the desired pitch can produce a different subset of valid number rises. However, while changing the number of rises alters, for instance extension lengths, it does not change anything prior to the selection of number of rises.

To restore the optimum pitch (recalculate all configurations and remove any modifications), select the default.

Click Next to display the Extension and Landings part of the Create Stair Flight window. Refer to Extension and Landings for further information.

Click Back to return to the Reference Points part of the Create Stair Flight window.

Click Cancel to discard any inputs and close the Create Stair Flight window.
