Stairs, Ladders and Handrails : Stair Flight : Detail Mode
The functionality available in the General Attributes part of the Create Stair Flight window is identical to that in Layout mode. Refer to General Attributes for further information.
The Reference Points 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 connections in the Pick Support Element functionality. The functionality is also applicable to the ‘TO’ Reference Point.
Use to select a support element (GENSEC) in the 3D view, selecting a support element offsets the stringer so that the stringer top of steel is flush with the top of steel of the support element. It also establishes a connection between the stringers and the support element and for this reason, only GENSEC’s are valid for picking. The support element must be horizontal. Click Pick Support Element, you are prompted to SLH - Stair Flight - Pick FROM Support Element.
Select the Connect check box to establish the connections.
In the structural hierarchy, JLDATU, PLDATU and FIXING elements are created to represent the joints to the GENSEC when the stair flight is built. Refer to Section Connectivity for further information.
The functionality available is identical to that in Layout. Refer to Reference Points for further information.
Click Next to display the Stair Configuration part of the Create Stair Flight window. Refer to Stair Configuration for further information.
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.
If required, you can offset the stair flight with respect to the centreline. Refer to Offset for further information.
Used for positioning the stair flight along the upper reference edge. Refer to Nudge for further information.
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.

Note:
|
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.
Click Next to display the Extension and Landings part of the Create Stair Flight window. Refer to Extension and Landings for further information.
The Extension and Landings part of the Create Stair Flight window, with Detail mode selected, has mostly the same functionality as that available from the Layout mode with the exception of the Stringer functionality.
From the Stringer Options part of the Create Stair Flight window, select the Crank Bottom of Stringers check box (only for stairs to a plane). The stringers of the stair are cranked at the selected plane and displayed in the 3D view.
From the Stringer Options part of the Create Stair Flight window, select the Extend Bottom Through Floor check box. The stringers of the stair are cranked at the selected plane and displayed in the 3D view.
You can specify if the landing (represented as a PANE element) is on top of or flush with TOS of the stringers, from the Finished Floor Level part of the Extensions and Landings window, select Above TOS or Flush with TOS.

Unlike Layout mode, adding handrails to a stair flight element in detail mode is a separate task using the Create Handrails functionality. Refer to Handrails for further information.
The Stair Summary part of the Create Stair Flight window, is populated with the main attributes of the stair flight.
Click Build Stair Flight to create a new stair flight element.
