What feature does the SNAP command primarily control in AutoCAD?

The SNAP command in AutoCAD is primarily used to control cursor movement. It adjusts how the cursor interacts with the drawing grid, creating specific increment settings that help users make precise placements and alignments in their drawing environment. When SNAP is activated, the cursor snaps to defined interval points based on the current SNAP settings, allowing for more controlled and accurate drawing, especially when creating geometric shapes or aligning objects.

By using SNAP effectively, users can create and modify elements in their drawings with a greater degree of precision, reducing the risk of errors that could arise from freehand cursor movement. This feature is especially beneficial when working on designing components that require a high level of detail or when ensuring that components align correctly within a larger design.
