Reference
Property description
Reference ID for this specified type in this project (e.g. type A-1 ), provided, if there is no classification reference to a recognized classification system used.
n/a
AcousticRating
Property description
Acoustic rating for this object. It is provided according to the national building code. It indicates the sound transmission resistance of this object by an index ratio (instead of providing full sound absorbtion values).
n/a
FireRating
Property description
n/a
Combustible
Property description
Indication whether the object is made from combustible material (TRUE) or not (FALSE).
false
SurfaceSpreadOfFlame
Property description
Indication on how the flames spread around the surface, It is given according to the national building code that governs the fire behaviour for materials.
n/a
ThermalTransmittance
Property description
Thermal transmittance coefficient (U-Value) of a material. Here the total thermal transmittance coefficient through the slab (including all materials).
0.
IsExternal
Property description
Indication whether the element is designed for use in the exterior (TRUE) or not (FALSE). If (TRUE) it is an external element and faces the outside of the building.
false
LoadBearing
Property description
Indicates whether the object is intended to carry loads (TRUE) or not (FALSE).
false
Compartmentation
Property description
Indication whether the object is designed to serve as a fire compartmentation (TRUE) or not (FALSE).
false
PitchAngle
Property description
Angle of the slab to the horizontal when used as a component for the roof (specified as 0 degrees or not asserted for cases where the slab is not used as a roof component). The shape information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the shape properties, provided in the attached property, the geometric parameters take precedence. For geometry editing applications, like CAD: this value should be write-only.
