Detail Hierarchy
When the STRFLT element is created in detail mode or converted from layout mode, below the STRFLT level in SLH hierarchy, the SLH specific elements are:
ROUTE PATH (RPATH)
The Routing Path element defines an open path or closed boundary using:
•
Free form sketching
•
Tracing existing profiles or boundaries.
ROUTE POINT (POINTR)
POINTR elements are significant point references which form the RPATH.
TOP EXTENSION (TOPEXT)
TOPEXT owns the PANEL element used to 3D model the physical representation of the top extension of the stair flight. 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.
BOTTOM EXTENSION (BOTEXT)
BOTEXT owns the PANEL and Stringer elements used to 3D model the physical representation of the bottom extension of the stair flight. 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.
INTERMEDIATE LANDING (INTLNG)
INTLNG owns the PANEL and Stringer elements used to 3D model the physical representation of the intermediate landing of the stair flight. 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 STRFLT.
PANEL, TMPL or Catalogue elements can be used to 3D model the rise or tread in the STRFLT.
STAIR STRINGER (STRSTR)
STRSTR owns the two GENSEC elements used to 3D model the main supports of the Stair Flight. The GENSEC elements are automatically mitred by the application at the upper and lower elevations of the STRSTR, dependent upon the relevant selections.
