Use the bearing and distance command (BD) to create an observation in reference to the occupied point using bearing and distance.
BD (point) [bearing] [quadrant] [distance] (description)
BD VA (point) [bearing] [quadrant] [distance] [vertical angle] (description)
BD VD (point) [bearing] [quadrant] [distance] [vertical distance] (description)
The following example illustrates using the BD command when the units are set to feet:
NE 1 100 100
STN 1
BD 2 45 1 100 PT
! BEARING: N 45-00-00 E DISTANCE: 100.0000
! POINT 2 NORTH: 170.7107 EAST: 170.7107
! ELEV: <Null>
This creates point 2 at the bearing and distance specified.
Point created with the BD command:
Point 2 is located by turning a bearing of 45°0'0" (50 grads) in Quadrant 1 (NE) at a distance of 100 feet from the instrument point with the description PT.

Parameter | Definition |
---|---|
point | The point identifier of the new point. You do not need to assign a point number if auto point numbering is on. |
bearing | The bearing. Enter this value in the current angular units (DMS, grads, decimal degrees, mils, or radians). |
quadrant | The quadrant for the bearing. Specify the quadrant using one of the following numbers: 1 (for NE), 2 (for SE), 3 (for SW), or 4 (for NW). |
distance | The distance from the instrument point to the point being located. It is measured in the current distance units. The distance is assumed to be a horizontal distance unless VA is used. When VA is used, the distance is recognized as a slope distance. |
vertical angle | The direction of the vertical angle (zenith, horizontal, or nadir). Type this value in the current angular units (DMS, grads, decimal degrees, mils, or radians). |
vertical distance | The elevation difference from the instrument to the prism. If the prism is higher than the instrument, then this is a positive value. |
description | An optional description associated with the point. |
