Polylines can be geometrically closed or logically closed. A geometrically closed polyline is essentially an open polyline for which the last node just happens to be at the same position as the first node. In a logically closed polyline with the same shape, the last node is omitted and the information that the polyline is closed is stored in the polyline instead. Logically closed polylines require one node less than geometrically closed ones. Logically closed polylines are often better suitable for further processing (CAM) than geometrically closed ones.

This tool converts all geometrically closed polylines into logically closed polylines.
