| Name | Target_Boundary_Segment |
|---|---|
| Entity Type | Table |
| 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 | Property / Storage Unit | Description | Required / Default | Type |
|---|---|---|---|---|---|
| Arc | double | Plane_Angle deg |
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 deg |
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. USAGE NOTES: There are two cases: 1) GUID is not populated or used; and 2) it is populated with a value that is globally unique. If the GUID is populated there are two means of doing so for a given project: 2a) Seabed automatically generates and populates the GUID when an instance is created (valid only on Oracle based systems); and 2b) the GUID is generated and populated by an application (other than Seabed) on instance creation. Whether Seabed automatically generates GUIDs for a project is determined by the Auto_GUID flag in SDS_Account. Note that techniques 2a and 2b can coexist in the same project. When GUIDs are automatically generated an application can override the automatically generated GUID with its own GUID by simply supplying the GUID value. Applications that generate their own GUIDs and populate the GUID column will function correctly on projects which have automatic GUID generation turned on. | No |
