COGO Expressions, Units, and Entry Formats
Mathematical expressions
You can enter numbers in many of the COGO controls. When a COGO control supports numeric entry, you can use basic mathematic expressions by including the operators as shown. The value is calculated when you leave the control.

Operator |
Example |
| Addition |
10+10 |
| Subtraction |
10-2 |
| Multiplication |
10*8 |
| Division |
8/4 |
| Power |
10^2 |
| Simple expressions
(for distance, bearing, and coordinate controls) |
5*(6+8) 052>054 (for distance or bearing between points) |
| Exponential notation
(for distance and coordinate controls) |
1.01E+6
|
| Separated formats
(for distance and coordinate controls) |
1,000,000 = 1000000 1.000.000 = 1000000 |
Units and data entry formats
The units, and entry and display formats, for data can be found and set in the Units section of the Project Settings dialog.
The current distance units, which are also used for the gridlines, display on the Status Bar. Distances that you enter are in these units. You can, however, enter other units in COGO controls by including a character for the type of unit. For example, if your project units are set to International foot, you can enter 3m in a COGO control to specify 3 meters. The unit you enter will be converted to the project units.
Entering point IDs
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.
