Stairs, Ladders and Handrails : Handrails : Detail Handrails Hierarchy
Detail Handrails Hierarchy
When the Handrail element (HANDRA) is created in Detail, below the SLH administrative elements, the HANDRA specific elements are:
Post Set (POSTSE)
The POSTSE is responsible for the ownership and management of multiple HRPOST elements.
Handrail Post (HRPOST)
The HRPOST element represents the post detail which references the catalogue items or templates as it has a SPREF attribute. The position of the HRPOST is defined with respect to the owning HANDRA in terms of its position along the path and the offset from the path of the HANDRA.
Rail Set (RAILSE)
RAILSE is responsible for the ownership and management of multiple RAIL elements whose physical representation is 3D modelled using a RAIL element.
Handrail Rail (RAIL)
RAIL is used to 3D model the detail representation of the individual RAIL elements and follows the path of the HANDRA, the RAIL references the existing catalogue steel profiles via its SPREF attribute and the position of the RAIL is defined with respect to the owning HANDRA in terms of its position along the path and the offset from the path of the HANDRA.
The RAIL shares the same underlying attributes and behaviour as the KICKPL element.
Handrail Kickplate Set (HRKPSE)
HRKPSE is responsible for the ownership and management of multiple Kickplate elements whose physical representation is 3D modelled using a KICKPL element.
Kickplate (KICKPL)
KICKPL is used to 3D model the detail representation of a kickplate and follows the path of the HANDRA, the KICKPL references the existing catalogue steel profiles via its SPREF attribute and the position of the KICKPL is defined with respect to the owning HANDRA in terms of its position along the path and the offset from the path of the HANDRA.
The KICKPL shares the same underlying attributes and behaviour as RAIL element.
Handrail Panel Set (HRPNSE)
HRPNSE is responsible for the ownership and management of multiple HRPANE elements.
Handrail Panel (HRPANE)
HRPANE is the database element responsible for the representation of 'panelised' sections of Handrail where the Panel size is determined by its Panel Size attribute. The detail of the HRPANE is represented using the existing database functionality of TMPL and FIXING elements and the route of the HRPANE elements is defined using the RPATH routing object.
Handrail Feature (HRFEAT)
HRFEAT owns HRGATE elements. The HRFEAT also owns RATTA elements which at this hierarchical level provide a connectivity mechanism to/from the boundary of the HANDRA.
Handrail Gate (HRGATE)
HRGATE is an element used to represent access locations along the path of the HANDRA. There can be multiple HRGATE elements in any HANDRA and the position of the HRGATE is managed by the application as a position along the RPATH element. HRGATE elements are managed as negative geometry and penetrate only the HANDRA. Additional detail for the HRGATE is represented using the existing database functionality of TMPL and FIXING elements.
Terminations (HRTERM)
The Termination element represents, for example, Loops, End Plates or Posts.
