Class structure

Implemented interfaces and base types

The PadFoundation is inheriting from the following base type(s) and implements the following interfaces:

Properties

Defining properties

The following properties are defined on the class

Name Type Description Quantity
Perimeter ICurve The edges used to define the outline of the pad at the top of the foundation. -
Property ISurfaceProperty Defines the thickness property and material of the PadFoundation. -
OrientationAngle double Defines the angle that the local x and y axes are rotated around the normal (i.e. local z) of the Panel.
The normal of the Panel is determined by the right hand curl rule dictated by the order of the edge list.
Local x is found by projecting the global X to the plane of the Panel and is then rotated with the OrientationAngle, except for the case when the Normal is parallel with the global X. For this case the local y is instead found by projecting global Y to the plane of the Panel and is then rotated with the OrientationAngle.
The remaining local axis is determined by the right hand rule.		 Angle [rad]
