Stairs, Ladders and Handrails : Step Ladder : Create Step Ladder
All of the SLADDR creation tasks are initiated from a central Create Step Ladder window which acts as a task hub. The General Attributes part of the window is always initially displayed, regardless of the selected SLH element or representation mode, further windows are presented (progressive disclosure) prompting for input.
 |
By default the Representation Mode is Layout and the General Attributes part of the Create Step Ladder window displays.
From the General Attributes part of the Create Step Ladder window, select a default standard from the drop-down list of available defaults. if there are no defaults, refer to the administrator, the default is Select.
The selected standard to which the default relates and the default tread width are automatically displayed in the General Attributes part of the Create Step Ladder window.
In the Name: field, type the name for the new SLADDR element, or select Autoname Step Ladder. The default is Unset.
If required, type in a description for the step ladder in the Description box. The default is Unset.
The Tread Width field specifies the tread width of the SLADDR element, it is automatically populated with the default of the selected standard (if set up by the administrator). If required, you can amend the tread width of the SLADDR element within the minimum and maximum defaults.
The Pitch field specifies the incline of the step ladder, it is automatically populated with the default of the selected standard (if set up by the administrator). If required, you can amend the pitch of the SLADDR element within the minimum and maximum defaults.
Select the Use Top Stringer Gap check box to create a stringer gap from the top edge to the top of the step ladder stringer (if edge to edge is used).
Select the Use Bottom Stringer Gap check box to create a stringer gap from the bottom edge to the bottom of the step ladder stringer (if edge to edge is used).
Click Next to display the Reference Points part of the Create Step Ladder window. Refer to Reference Points for further information.
The Step Ladder Summary part of the Create Step Ladder window is populated with the Pitch angle and Tread Width dimension of the SLADDR element.
To create a new SLADDR element, you must select a start (FROM Reference Point) and end (TO Reference Point) from the Reference Points part of the Create Step Ladder window. By default no reference points are selected.
The functionality available in the Reference Points part of the Create Step Ladder window is identical to the Reference Points part of the Create Stair Flight window (with the exception of the Edge to Calculated Position functionality). Refer to Reference Points for further information.
Click Next to display the Step Ladder Configuration part of the Create Step Ladder window. Refer to Step Ladder Configuration for further information
By default, the Step Ladder Configuration part of the Create Step Ladder window is populated with all the allowable configurations.
The configurations that display in the Step Ladder Configuration part of the Create Step Ladder window is dependent upon which defaults are set by the administrator.
