Drawing with Snapping and Constraints

SmartCursor snapping allows you to draw with precision. Used in conjunction with drawing tools, the SmartCursor uses snap indicators, hints, extension lines, text (SmartCursor cues), and sounds, and then precisely snaps the cursor based on the snapping categories enabled in the Constraints palette.

Parametric constraints ensure that a drawing maintains its original precision. Constraints preserve geometric relationships between an object and world space, between two objects, or within an object.
