What feature does AutoCAD use that is indicated by green dotted reference lines?

1. Dynamic input

2. Object snap tracking

3. Grips

4. Polar tracking

The correct answer is: Object snap tracking

The feature in AutoCAD that is indicated by green dotted reference lines is object snap tracking. This feature enhances object snapping by allowing users to track and create reference lines to existing objects in the drawing. When moving the cursor near the selected object, these green dotted lines appear, guiding the user to snap to specific points on that object. The purpose of object snap tracking is to provide precision when aligning and connecting different elements within the drawing. By using these reference lines, you can efficiently create geometries that are accurately positioned relative to other features, ultimately improving the drafting workflow and ensuring that designs are geometrically correct and aligned. In contrast, dynamic input displays information and prompts near the cursor for more interactive command input but does not involve reference lines. Grips are used to manipulate objects directly by displaying control points but do not produce any tracking lines. Polar tracking aids in creating angles based on specified increments or angles but is represented by different line styles, like the dashed lines associated with angle increments, rather than the green dotted lines associated with object snapping.
