Snaps Modes and Commands

Snaps use geometric calculations to help you specify and select coordinates and points more easily and accurately. Snaps can either use existing geometry or values that you enter during the command. There are two types of snap functions:


Snaps
Running snap modes	These modes are similar to the snap commands, except that (when enabled) they are always active. The running snap modes establish the order of precedence for the point snap modes. They can be temporarily overridden by using a specific snap command. Note: Running snaps are available only for point (coordinate) snaps. There are no running snaps for angle, bearing, distance, offset, elevation, or station controls.
Snap commands	These commands enable you to enter angles, bearings, coordinates, distances, elevations, and offsets to calculate coordinates in your project. You can also select (or enter) applicable objects, such as breaklines, alignments, surfaces, and point IDs in snap commands.
