Use the deflection distance (DD) command to quickly create a point using a deflection angle and distance from an established line.

The term deflection angle refers to the angular direction turned from the extension of the previous course. Additionally, you can also use a vertical angle or vertical distance to locate the point.

DD (point) [angle] [distance] (description)

DD VA (point) [angle] [distance] [vertical angle] (description)

DD VD (point) [angle] [distance] [vertical distance] (description)

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. |

angle | The deflection angle as measured to the point. Type this value in the current angular units (DMS, grads, decimal degrees, radians, or mils). |

distance | The distance from the instrument point to the point being located. It is measured in the current units unless otherwise specified. 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. |
