Use the COGO Editor to create and adjust 2D traverses.
Graphical Preview and Object Insertion
Temporary graphics, as shown in the following example, are displayed in the drawing when you enter traverse data in the COGO Editor.
These graphics disappear when you close the COGO Editor. You can use the Create Polyline From Traverse 
and Add COGO Points to Drawing 
options to insert objects into the drawing that are based on the traverse data.
When you select an adjustment method on the Balance tab, additional graphics are displayed in the drawing to show the effects of the adjustment.
General Guidelines for Entering Data
You can load data into the COGO Editor by selecting an existing polyline in the drawing or by manually entering known data. You can use a variety of formats and mathematical equations to quickly enter traverse data.
- Use the Tab, Enter, or arrow keys to navigate between cells.
- The values you enter in the COGO Editor are not affected if the traverse is adjusted.
- 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'.
Note: The 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
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 COGO 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.
