Understanding COGO Controls

COGO (COordinate GeOmetry) controls are the boxes in various commands that help you calculate angles, bearings, coordinates, distances, elevations, and offsets in your project. They enable you to enter data in a variety of ways, including:

  • Typing values and point IDs in the box
  • Picking points in graphic views
  • Right-clicking in graphic views and selecting additional snap and COGO options from the context menu

COGO controls give you this flexibility so that you have many ways in which you can enter data within a single command, rather than forcing you to work through multiple commands.

Since COGO controls are used in many commands, once you understand how to use them, you will be able to apply your knowledge all to the commands that use them.

COGO cursors

Depending on the type of control you are in, the appearance of the cursor changes in graphic views. The name of the control also appears on the status bar, and the status line's tooltip tells how use the control.
