Detail Hierarchy
When the element is created in detail mode or converted from layout mode, below the SLADDR level in SLH hierarchy, the SLH specific elements are:
TOP EXTENSION (TOPEXT)
TOPEXT owns the PANEL element used to 3D 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 or each connected end of a Panel Linear Joint.
TREAD SET (TREADS)
The TREADS element is used to manage the ownership of individual TREAD elements.
TREAD (TREAD)
TREAD owns the elements used to 3D model the rise or tread in the STRFLT. 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 Catalogue elements can be used to 3D model the rise or tread in the SLADDR.
STAIR STRINGER (STRSTR)
STRSTR owns the two GENSEC elements used to 3D model the main supports of the Step Ladder. The GENSEC elements are automatically mitred by the application at the upper and lower elevations of the STRSTR, dependent upon the relevant selections.
