Class TIfcAxis2Placement3D

Fields

Unit

type TIfcAxis2Placement3D = class(TIfcPlacement)

Location and orientations to place items in a three-dimensional space.

	`function P(const AxisCoord: T3DAxis): TVector3;`
	`procedure GetTransform(out Translation: TVector3; out Rotation: TVector4); override;`

	`property Axis: TIfcDirection read FAxis write FAxis;`
	`property RefDirection: TIfcDirection read FRefDirection write FRefDirection;`

	`function P(const AxisCoord: T3DAxis): TVector3;`
Axes of the created coordinate system. Always normalized and orthogonal.

procedure GetTransform(out Translation: TVector3; out Rotation: TVector4); override;

This item has no description. Showing description inherited from TIfcPlacement.GetTransform.

Get translation and rotation defined here. Rotation is expressed just like TCastleTransform.Rotation and TTransformNode.Rotation, so it's axis and angle (in radians).

	`property Axis: TIfcDirection read FAxis write FAxis;`
Direction of the local Z axis. May be `Nil`.

	`property RefDirection: TIfcDirection read FRefDirection write FRefDirection;`
Direction of the local X axis. May be `Nil`. If necessary an adjustment is made to maintain orthogonality to the Axis direction. If Axis and/or `RefDirection` is omitted, these directions are taken from the geometric coordinate system.
