Derived properties

The following properties are defined as extension methods in one of the BHoM_Engines

Name	Type	Description	Quantity	Engine
Description	string	Generates a default description for the Section as 'Concrete ProfileDescription - MaterialName'.	-	Structure_Engine
DescriptionOrName	string	Gets the name from a IProperty. If null or empty, a default description name is provided instead.	-	Structure_Engine
Geometry	IGeometry	Gets the geometry of a GeometricalSection as its profile outlines the global XY plane. Method required for automatic display in UI packages.	-	Structure_Engine
HasModifiers	bool	Checks if a SectionProperty has any modifiers by first checking if any modifiers has been assigned, and if any of them are set to a value different than 1.	-	Structure_Engine
HasReinforcement	bool	Returns true if the ConcreteSection has BarRebarIntent defined with at least one IBarReinforcement in it. False if the ConcreteSection or BarRebarIntent is null or the IBarReinforcement count is zero.	-	Structure_Engine
IDescription	string	Generates a default description for the SectionProperty, based on type, profile and material.	-	Structure_Engine
IDescription	string	Generates a default description for the IProperty, based on its properties.	-	Structure_Engine
IGeometry	IGeometry	Gets the geometry of a SectionProperty, generally as its profile outlines the global XY plane. Method required for automatic display in UI packages.	-	Structure_Engine
IMassPerMetre	double	Calculates the mass per length for the section, generally as its area mulitplied by the density. General dispatch method that calls the correct method based on type.	MassPerUnitLength [kg/m]	Structure_Engine
IMaterialComposition	MaterialComposition	Returns a SectionProperty's MaterialComposition.	-	Structure_Engine
InvalidSectionProfile	bool	-	-	Lusas_Engine
InvalidSectionProperty	bool	-	-	Lusas_Engine
IsNull	bool	Checks if a SectionProperty is null and outputs relevant error message.	-	Structure_Engine
IVolumePerLength	double	Calculates the volume per length for the section, generally as its area mulitplied by the density. General dispatch method that calls the correct method based on type.	MassPerUnitLength [kg/m]	Structure_Engine
LongitudinalReinforcementLayout	List<Point>	Gets the LongitudinalReinforcement positions in the ConcreteSection as a list of Points.	-	Structure_Engine
MassPerMetre	double	Calculates the mass per length for the section as its area times density. Does not take any reinforcement into acount.	MassPerUnitLength [kg/m]	Structure_Engine
MaterialComposition	MaterialComposition	Returns a ConcreteSection's MaterialComposition, taking into account any LongitudinalReinforcement.	-	Structure_Engine
Modifiers	double[]	Gets any modifiers from a section as an array of doubles. The modifiers are used to scale one or more of the section constants for analysis. Constants are multiplied with the modifiers, hence a modifier value of 1 means no change. The values returned are in the following order: Area, Iy, Iz, J, Asy, Asz. Method returns null if no modifiers are found.	-	Structure_Engine
ReinforcementLayout	List<IGeometry>	Gets the IBarReinforcement positions in the ConcreteSection as a list of points (centers) and curves (centerlines).	-	Structure_Engine
ReinforcementTransitionPoints	List<double>	Returns a list of the normalised locations (0 means start, 1 means end) in the cross section where the reinforcement changes. If section is null or does not contain any reinforcement, an empty list will be returned.	-	Structure_Engine
TransverseReinforcementLayout	List<ICurve>	Gets the TransverseReinforcement positions in the ConcreteSection as a list of Curves (centerlines).	-	Structure_Engine
