Name	Target_Boundary_Segment
Entity Type	Extension of Target_Shape
Description	This table describes a single segment of a drill target face boundary. It may be a line, arc, or point. It has a starting point usually defined by the position and orientation of the end of the previous boundary segment. The order in which boundary segments must be traversed is defined by the segment number. The meaningful dimensions of the segment are defined by the segment type.

Name	Value Domain / Measurement	Description	Required / Default	Type
Arc	double Plane_Angle	Angle of arc for continuous curve segment, measured from segment starting point location. Offset to center is to right if positive, to left if negative.	No	NUMBER
Azimuth	double Plane_Angle	Azimuth of straight line segment, or beginning azimuth of a curved segment, from starting point location using frame of reference of the target	No	NUMBER
Existence_Kind	REF_EXISTENCE_KIND NA	A reference value that describes the state of existence in the lifecycle of the entity, for example, Planned, Predicted, Required, Simulated, and Actual.	Yes Actual	VARCHAR2(64)
GUID	STRING128 NA	Globally Unique IDentifier for an instance of a class. This GUID is not generated by the database, but is the GUID used by the application on first access of this object. Use of this property is optional and completely under the control of application developers.	No	VARCHAR2(128)
Id	ID No_Unit	Unique identifier for this entity.	Yes	NUMBER(38)

Length	double Length	Length of straight line segment	No	NUMBER
Produced_By	STRING64 NA	ID of the activity that was executing when the entity was created, for data created programmatically.	No	VARCHAR2(64)
Radius	double Length	Radius of arc for continuous curve segment. Center assumed to be offset from start point normal to its beginning azimuth; positive value is to right, negative to left	No	NUMBER
Relative_Easting	double Length	Easting of the point (if type is Point) or the starting point (for other types), measured from target ref point location in target relative coordinates	No	NUMBER
Relative_Northing	double Length	Northing of the point (if type is Point) or the starting point (for other types), measured from target ref point location in target relative coordinates	No	NUMBER
SDAT_Label	int No_Unit	Label used by the security system for entitlements. SDAT is Secure Data Access Technology.	No	NUMBER(10)
Segment_Number	int No_Unit	Sequence number of segment, 1,2,3?	Yes	NUMBER(10)
TVT_Above	double Length	Vertical thickness of target above segment starting point	No	NUMBER
TVT_Below	double Length	Vertical thickness of target below segment starting point	No	NUMBER
Target_Shape_Id	Target_Shape	Defines a segment of a	Yes	NUMBER(38)
Thickness_Above	double Length	Thickness of target above segment starting point, measured normal to reference plane	No	NUMBER
Thickness_Below	double Length	Thickness of target below segment starting point, measured normal to reference plane	No	NUMBER
Type	CODE NA	Kind of target segment this is	Yes	VARCHAR2(64)
Update_Date	DATE NA	Date of the most-recent modification to the entity.	No	DATE
Update_User	STRING64 NA	The name of the user responsible for the last modification to this entity.	No	VARCHAR2(64)
