Enter a Coordinate

Use the Coordinate control to specify X, Y, and Z, or latitude, longitude, and elevation coordinates of a point. If a Z or elevation coordinate is entered in the coordinate control, and there is also an elevation control for the same point, the value will be placed in the elevation control. "Coordinate" appears on the Status Bar when the command is active.

To specify a coordinate:

  • Pick a point in a graphic view. If no running snap modes are enabled, the default operation does not specify a Z coordinate. If running snaps are enabled, the cursor will potentially snap to a location and use its Z value based on the snap mode.
  • Type a point ID in the coordinate box using any of the standard entry formats. If there are multiple points with the same ID, then the one with the best quality is used. Check and set the entry format in the Project Settings by selecting Project Settings > Units > Coordinate.

    Note: If you enter a point ID for a single value, such as an elevation, type quotation marks around the point ID to distinguish it as the elevation of the point, not just an elevation value. For example, to use the elevation for point 1001, type "1001" in the control. In coordinate controls where you are entering a pair of coordinates, typing the point ID without quotes will suffice. The coordinates of the point are used.

  • Type two or three numbers separated by a space or comma to specify a coordinate pair or triplet, in the format N, E, (Z). The separator is user-definable in the Project Settings. Typically, spaces or commas are used to specify coordinate pairs or triplets.

    Examples:   27,42, (1)

                      27 42 1

                      27,42

                      27 42

In the Plan View, these normally represent N, E, (Z). In the Profile View these normally represent station and elevation. The control honors the ordering of the X and Y values as specified for the current view.

Although you will usually be entering grid based coordinates, you can also enter latitude and longitude coordinates in the format Latitude, Longitude, (Z). To do this, a coordinate system must be defined for the project. Do not use spaces to separate the coordinates because spaces are used to separate the angle components.

Examples:   N40°35’18.12345”, E120°23”12.32145”, 1000

                  N40 35 18.12345, E120 23 12.32145, 1000

                  N40 35 18.12345, E120 23 12.32145

To specify a relative coordinate:

Type an @ before a value to specify a relative distance from a previous point (when the cursor has an anchor point). The @ symbol must be used before each relative coordinate, but you can enter both relative and absolute coordinates in the same control. The relative distance separator is user-definable in the Project Settings, but typically, @ is used as shown.

Examples:   @27,@42

                  @27 @42

In any view with a vertical exaggeration you can substitute a grade (G) for the elevation when setting a point relative to a previous point. This can be used in conjunction with a relative (@S) station value. Valid entries for grade are: (%, or P) for percent of grade and (:, or R) for ratio grade, e.g. 2:1.

Examples:   @500,2%

                  @500 2P

In any view with a vertical exaggeration, you can substitute a Maximum (M) depth for the station and grade (G) for the elevation when setting a point relative to a previous point. The maximum depth will be the change in depth (elevation) from the previous point. Valid entries for grade are: (%, or P) for percent of grade and (:, or R) for ratio grade, e.g. 2:1. This type of entry is typically used in defining templates used with roads.

Examples:   5,2%

                  5 2%
