Type
Sets the origin. A Standard origin has fixed coordinates in all directions (E/W, N/S, and U/D). When you select Partial, you must use the check boxes to specify which direction has a fixed coordinate.
Set as Start Point
Defines the 3D coordinate as the start point. This option is available only when the origin is placed at the open end of the pipe route.
Coordinates
Sets the units for each direction. To specify a West, South, or Down coordinate, type a negative value. For example, to specify 1000mm West, type -1000 in the East/West box.
Offset
Specifies how the software interprets the coordinates you enter. If you select Global Offset, the software determines the actual coordinates of the origin by adding the global offset defined for the pipeline to the Coordinates settings that you define. If you select Absolute, the Coordinates settings that you define are the actual values of the origin. The dialog box displays this option only if a global offset is defined for the pipeline.
