The functionality of the ASL application provides the means to quickly create, modify and verify the suitability of particular designs or layouts of rule based assemblies for the ASL elements.
The ASL functionality is a sub application of the Structures application. To access ASL, select Design > Structures > Access, Stairs and Ladders from the main toolbar.


The specific forms for the creation of the following elements and their members are displayed either by selecting them from the Create, Modify or Toolbar options from the main toolbar.
-
Stair Tower (STRTWR)
-
Stair Flights (STRFLT)
-
Ladder (LADDER)
-
Platform (PLTFRM)
-
Handrail (HANDRA)


The modification functionality of the ASL application is accessed from the Modify > ASL element pull down.

The form shown below is typical of the layout of all the ASL forms. All can be docked and allows you to Create, Modify or Delete the ASL elements via 'link labels' that guide you through the main tasks associated with the purpose of the ASL elements and their sub elements.

The links are context sensitive to the current location in the hierarchy where they become active when situated below a STRU hierarchy; this is the owning element for all the ASL assemblies. When any of the ASL assemblies is the current element the relevant link will highlight for the appropriate Create, Modify or Delete task.
