Positioning and Orientating Primary Joints

Keywords

DELPOSITION OPDIRECTION  BANGLE

Description

The position and orientation of a Primary Joint are defined by the settings of the following three attributes:

• The Delta Position (DELP) is the offset between the Joint’s Origin Plane and the position of its owning Node (the NPOS of the PNOD), expressed in the coordinate system which applies to the FRMW or Subframe (SBFR). The default is a zero offset, so that the Joint’s Origin Plane passes through the owning Node.

• The Origin Plane Direction (OPDI) is the direction of the normal to the plane through the Joint’s origin, as defined in the Catalog representation of the Joint.

• The Beta Angle (BANG) is the angle of rotation of the Joint about its Origin Plane Direction, measured clockwise as viewed along that direction. The default setting is zero, so that the Joint’s orientation is as defined by its Catalog representation.
