Final answer:
The Close option in CAD programs is used to connect the last point of a polyline with the first, creating an enclosed shape, not to remove the last segment added. The statement is false.
Step-by-step explanation:
The statement is false. When editing a polyline in CAD programs, the Close option is used to create a line or arc that closes the shape by connecting the last point with the first, not to remove a segment. This feature is designed to complete a given polyline to form an enclosed shape, which is particularly useful in various drafting, design, and engineering tasks.
