IJUAhsSteelSection::SteelName
Specifies the steel section name.
IJUAhsSteelSection::SteelType
Specifies steel section type name.
If SteelType is set to Pipe, then the section is placed in a vertical orientation. All other types place in a horizontal orientation.
IJUAhsSteelSection::SteelStandard
Specifies steel section standard.
IJUAhsSteelCPoint::SteelCpoint
Specifies the cardinal point of the steel section.
Cardinal points
Cardinal points specify anchor locations on a steel section. The following 15 cardinal positions are available. They are defined on the CrossSectionCardinalPoints codelist sheet in the Allcodelists.xls workbook.

Shear Center
The location of cardinal points 10 (center-of-gravity) and 15 (shear center) depend on the section shape. The local z-axis of the member and the center-of-gravity point of the section define cardinal points 11 and 14. The local y-axis of the member and the center-of-gravity point of the section define cardinal points 12 and 13. The locations of the cardinal points are shown below for the different steel sections. Because cardinal points 10 to 15 are specific to each section shape, only cardinal points 1 to 9 are shown in the images:
IJUAhssteelAngle::SteelAngle
Specifies the rotation angle of the steel section along its x-axis. The property determines the angle by which the steel section is rotated along its length. The steel section is anchored on the specified cardinal point when it is rotated. In the image shown below, the T-section is anchored at cardinal point 2. After the angle of the steel is rotated by 90 degrees, the steel section is positioned where the dotted line is located.
