Object Snap, commonly referred to as OSNAP, is a crucial feature in AutoCAD that enhances precision during drafting and design work. It allows users to easily select specific geometry points on objects, such as endpoints, midpoints, and intersections. By using OSNAP, you can snap your cursor to these predefined points, ensuring that your lines and shapes are accurately placed relative to existing geometry.

This is particularly beneficial in workflows where precision is vital, such as architectural or engineering designs. The ability to snap to various object points saves time and reduces potential errors, as you are not relying on visual approximation but rather on exact alignment with the model's existing forms.

The other options do not capture the same functionality. While "Object Scale," "Object Layer," and "Object Path" might refer to different aspects of AutoCAD's capabilities, they do not pertain to the snapping feature that OSNAP provides. In summary, Object Snap is essential for creating accurate and efficient designs in AutoCAD.
