Enter traverse data using a variety of formats and mathematical equations.

The Coordinate Geometry Editor enables you to enter and modify 2D traverse data. You can use a variety of formats and mathematical equations to quickly enter traverse data either numerically or from known COGO data.

General Guidelines for Entering Data

  • Use the Tab key to quickly navigate between cells.
  • If an entered value is red, it is invalid.
  • The values you enter in the Coordinate Geometry Editor are not affected if the traverse is adjusted, scaled, or rotated.
  • To use another unit of measure, enter either ‘ or m.

    For example, if you are working in a metric drawing and want to enter a value in feet, enter 200‘.

    NoteThe unit of measure calculation depends on the parameters specified on the Units and Zone tab of the Drawing Settings dialog box:
    If Drawing Units is set to: and Imperial to Metric Conversion is set to: and the suffix is: then the distance conversion is:
    Feet US Survey Foot m meters to US survey foot
    Feet International Foot m meters to international foot
    Meters US Survey Foot ‘ US survey foot to meters
    Meters International Foot ‘ international foot to meters

Data Formats

You can use the following formats to enter data into the Coordinate Geometry Editor:

Latitude and Longitude

Use the Latitude/Longitude format that is defined in the drawing settings to specify XY formatting of the point of beginning and point of closure.

Enter known degrees, minutes, and seconds in any of the following formats:

  • DDMMSS.ss
  • DD MM SS.ss
  • DD.MMSSss

Quadrant Location

Use compass quadrant location format to specify direction.

Enter known directions by quadrant number and then angle, in any of the following formats:

  • 1..45 = N 45 E
  • 3..30 = S 30 W

COGO Point Location

Use COGO points to specify direction, angle and distance values.

Click to select a COGO point in the drawing, or enter either PT1 to PT2 or 1 to 2, use the relative value between points 1 and 2, enter in any of the following cells:

  • Angle/Direction
  • Distance
  • Radius
  • D Angle

Drawing Location

Pick locations in the drawing to specify X/Y coordinates, directions, distance, radius, or D angle.

Click , and then click two points in the drawing.

Unknown Value

If a value is not known, enter U in the cell. The Coordinate Geometry Editor will calculate the value based on the other, known values.

Note

Up to two values per traverse may be unknown. Two unknown values can used in the same traverse side. If there are multiple solutions, the possible solutions are displayed in a dialog box and you can select one of them to use. Multiple solutions are possible when you have two sides with known lengths but unknown directions.

Using Mathematical Equations to Calculate Traverse Parameters

You can enter a variety of mathematical equations to calculate traverse parameter values. The equations enable you to enter known data, such as the relative location of COGO points, when you define a traverse.

The following operators are valid:

  • +
  • -
  • /
  • *
  • ( )

The following equations are simple examples of how to enter data in the Coordinate Geometry Editor:

Equation Result
(1 to 2)/2 Calculate the angle, direction, or distance between points 1 and 2, and then divide the result by 2.
100+200+150 Return the sum of multiple values.
Note

This type of equation is useful for calculating the total distance of several, contiguous lot lines.
