Enumeration definition

Constant	Description
CURTAIN_PANEL	A planar element within a curtain wall, often consisting of a frame with fixed glazing.
SHEET	A planar, flat and thin element, comes usually as metal sheet, and is often used as an additonal part within an assembly.
FLANGE_PLATE	A flange plate in linear members having box or I-profile (e.g. top or bottom flange plate in box-girder).
WEB_PLATE	A plate connecting flange plates in linear members having box or I-profile.
STIFFENER_PLATE	A transversal plate added to a flange or a web plate for local stiffening.
GUSSET_PLATE	a plate or bracket for strengthening an angle in framework (as in a building or bridge).
COVER_PLATE	A plate (underneath or above) a flange to provide additional load capacity.
SPLICE_PLATE	A plate connecting two members joined at ends.
LAGGING	Lagging is the structural material (most often wood) that spans the distance between spars at an excavation site. Lagging, and the steel spars they connect to, provides temporary ground support as a safety measure during tunneling. The lagging is installed horizontally between vertically installed spars.
BASE_PLATE	A plate used to spread load over a surface, such as underneath a bearing or column.
USERDEFINED	User-defined linear element.
NOTDEFINED	Undefined linear element.
