Step Ladder (SLADDR) Hierarchy

The Step Ladder element (SLADDR) is a top level administrative element owned by a STRU element.

The SLADDR as a steelwork assembly enables the user to create a rule based linear step ladder and it introduces a middle tier hierarchy to enable the decomposition of the SLADDR assembly into its logical component parts, the existing lower level elements of GENSEC and PANEL are used to represent the detail of the 3D model.

Stair Stringer (STRSTR)

STRSTR owns the two GENSEC elements used to model the main supports of the Step Ladder. The GENSEC elements are automatically miterd by the application at the upper and lower elevations of the STRSTR, dependent upon the relevant selections.

Tread Set (TREADS)

The TREADS element is used to manage the ownership of individual TREAD elements.

Tread (TREAD)

TREAD owns the elements used to model the rise or tread in the SLADDR. The vertical position between the Tread is measured from Top of Plate to the next Top of Plate and represents the Rise attribute on the SLADDR.

PANEL, TMPL or Catalog elements can be used to model the rise or tread in the SLADDR.

Top Extension (TOPEXT)

TOPEXT owns the PANEL element used to model the physical representation of the top extension of the step ladder. It is defined by the extrusion of a profile representing the panel's shape (the Panel Loop. PLOOP) through a given distance (equivalent to the panel thickness). A PAVE element defines each vertex of a Panel Loop.

Step Ladder Rail (SLRAIL)

SLRAIL owns the GENSEC elements used to model the rails of the Step Ladder.
