Traverse Editor

Use the Traverse Editor to enter traverse data and then send the data to the Traverse Adjustment dialogue box where you can apply an adjustment method to the data.

Tools

New

Creates a new traverse.

Open

Opens an existing traverse file. You can open a TRV2 file (the current file format) or a TRVX file (an earlier file format created in the previous coordinate geometry editor tool). When the file is opened, the Traverse Editor is populated with the traverse data and a preview of the traverse is displayed in the drawing.

Load From Entity

Loads traverse data from a polyline, automatically creating traverse sides between each polyline vertex.

Save

Saves the traverse to a TRV2 file.

Save As

Saves a copy of the traverse to a TRV2 file.

Load Balance Tool

Saves the current traverse file, closes the Traverse Editor and opens the traverse file in the Traverse Adjustment dialogue box.

Draw List

Use these options to specify whether to create a polyline, COGO points, or both as you enter side data.

The points that are created in the drawing will use the default point style and point label style specified in the point feature settings unless you enter description keys in the Description column of the Traverse Editor. Polyline objects are created on the current layer. The temporary graphics that are displayed in the drawing use the colour of the current layer.

Lines

Creates a polyline in the drawing as you enter traverse data. Polyline vertices are created at the beginning and end of each traverse side.

Points

Creates COGO points at the beginning and end of each traverse side as you enter traverse data. These COGO points are dynamic to the traverse. If you edit data in the Traverse Editor so that the traverse is changed, the COGO points that are derived from the traverse will move accordingly.

Note: Points that are created are listed in the COGO Point column.

Points and Lines

Creates a polyline and points from the traverse.

Zoom List

Zoom Extents

Zooms to the extents of the traverse as you add new sides.

Zoom Current Row

Zooms to the current row of the traverse as you add a new side.

No Zoom

Does not zoom the view when adding new sides.

Draw Lines and Arcs List

Lines and Arcs

Displays the Arc columns in the table so you can enter arc data.

Lines

Hides the Arc columns in the table.

Settings

Opens the Traverse Editor Settings dialogue box.

Data Entry Table

Tip: Right-click in the Traverse Editor to access commands for inserting, deleting, or reordering the rows and copying data.

Side

Specifies the type of traverse side to create: Point, Line, Radial Arc, Chord Arc, or Side Shot.

The first side type of the traverse must be a point which represents the start point (SP). To specify the SP, select a point or a location in the drawing or enter a point number and then enter an optional angle to define the initial backsight line.

Occupied Point

Specifies the occupied point for the start point and any Point side type.

Point - Line - Chord

Use these columns to enter data for points, lines, and chords.

Note: To enter chord data, select Chord Arc as the Side type and enter the angle and distance in the Point - Line - Chord section of the Traverse Editor and enter the radius, Δ angle or length in the Arc section of the Traverse Editor.

• Angle: Specifies the angle for the traverse side.
  You can enter angles using several methods. Letters in entries may be capitalized or lower case.

  Angle Entry Types

  Angle Entry Type	Example/Description
  Directions	N S E or W Note: North, South, East, and West can also be used.
  Directions and angle	N30W (bearing) or N45 (whole circle bearing)
  Quadrant and angle	1..45, where 1 is the quadrant and 45 is the angle.
  Right or left turned angle	R45 or L45 Note: This angle is turned from the foresight.
  Degrees, minutes, and seconds	63 51 25 Tip: You can also enter DMS angles in decimal format such as 63.5125 if the Direction setting in the Traverse Editor Settings dialogue box is set to decimal DMS. Note: This angle is turned from the backsight. Entering minutes and seconds is optional.
  Decimal degrees	63.8569 Tip: You can enter angles as decimal degrees if the Direction setting in the Traverse Editor Settings dialogue box is set to Decimal.
  The angle between two COGO points	1...2 where 1 and 2 are the COGO point numbers or CP1...CP2 where CP1 and CP2 are COGO point names.
  Selected locations	Click . You can then select one point in the drawing to define the direction from the occupied point. Alternately, you can also enter P for Point at the command line and then pick two points to define the angle.
  Mathematical equations	100 + 200 Note: The following operators are valid: + - / *

• Distance: Specifies the distance of the traverse side.
  You can enter distances data using several methods.

  Distance Entry Types

  Distance Entry Type	Example/Description
  Numeric	100, 100m, 100' Note: For more information about entering numeric unit suffixes, see About the Traverse Editor.
  COGO points	1...2 where 1 and 2 are the COGO point numbers, or CP1...CP2 where CP1 and CP2 are COGO point names.
  Selected locations	Click . You can then select one point in the drawing to define the distance from the occupied point. Alternately, you can also enter P for Point at the command line and then pick two points to define the distance.
  Mathematical equations	100 + 25 Note: The following operators are valid: + - / *

Arc

Use these columns to enter data for arcs.

Data that you enter is shown in regular font. Data that is calculated is shown in italic font.

After you enter data into the arc fields, other arc data is calculated. You can change the way the arc is calculated by entering different data into a field that was calculated. That field will then be shown as regular font and the other fields that have been calculated will be updated and shown in italics. For more information, see To Input Traverse Data in the Traverse Editor.

• Radial: Specifies the radial direction (the angle to the radius point (centre point) of the curve) for a radial arc. For information about methods for entering angles, see the Angle Entry Types table above.
• Radius: Specifies the radius of the arc. For information about methods for entering radius data, see the Distance Entry Types table above.
• Δ Angle: For a straight curve or radial curve, specifies the central angle, measured from the center of the curve, from the beginning of the curve to the ending point of the curve. A positive delta angle indicates the arc goes clockwise while a negative delta angle indicates the arc goes counter-clockwise. For information about methods for entering angles, see the Angle Entry Types table above.
• Length: Specifies the length of the arc. For information about methods for entering length data, see the Distance Entry Types table above.

Coordinate

Displays the calculated coordinates of the end of the side.

COGO Point

Specifies the names (numbers or alpha-numeric names) and descriptions of the COGO points that are created as you enter data.

Name

Displays the alpha-numeric name of each point. The next available point number in the drawing is used as the first point name that is assigned.

You can change the alpha-numeric point name that has been generated and the next point will increment from that point.

For example, if you change point 1 to point 100, the next point created will be point 101.

If you change point 1 to point CP100, the next point created will be point CP101.

Description

Specifies the raw description for each point. You can use description keys when entering the description and the description key style will be applied to the point that is created in the drawing.
