Question: Explain the difference between absolute and relative coordinates in AutoCAD.

Answer: Absolute coordinates are fixed points on the XY plane, while relative coordinates are measured from the last point specified. Absolute coordinates use a fixed origin point, usually (0,0), while relative coordinates are based on the current position.

Example:

Absolute coordinates: (5,10), Relative coordinates: @2,3 (moves 2 units along X and 3 units along Y from the last point).
