Material type

When a material is pushed to Lusas, a generic Isotropic Material will be created irrespective of the type provided. When the material object is pulled from Lusas, the type will default to Steel.

Section Properties

Steel Sections

BHoM Type	Lusas Type	Notes	Implementation
RectangleSection	Rectanglular Sections - Solid		Read Write
BoxSection	Rectangular Sections - Hollow Equal Thickness		Read Write
FabricatedBoxSection	Rectangular Sections - Hollow Unequal Thickness	1. Lusas does not support different flange thicknesses. When pushing the top flange thickness is used as the flange thickness. 2. Lusas does not support a weld size, assumed to be the inner radius.	Read Write
CircleSection	Circular Sections - Solid		Read Write
TubeSection	Circular Sections - Hollow		Read Write
ISection	I Sections - Equal Flanges		Read Write
TSection	TSection		Read Write
FabricatedISection	I Sections - Unequal Flanges	Lusas does not support a weld size, assumed to be the root radius.	Read Write
AngleSection	L Sections - Single		Read Write
ChannelSection	C Sections - Unlipped	1. Channel section implemented through section by profile 2.Toe radius not supported by Lusas	Read Write
ZSection	Z Sections - Unlipped	1. Unequal flange thickness is not supported by Lusas, the flange thickness is used as the thickness when pushed. 2. Toe radius is not supported by Lusas.	Read Write
