Extension and Landings

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.

If required, you can crank the bottom of the stringers or extend them through the floor.

Cranked Bottom

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.

Extend Bottom Through Floor

Where the bottom of a stair flight is coming down to a plane which may be, for example a grated or plated platform, the stringers may need to be extended through the thickness of the grating/plating to support members below.

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.

Landing Floor Finish Level

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.

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

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

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