Feature Description

Auto-close Lines command is used to automatically close features when drawing polylines, curves, polylines, or free curves.

The drawn line feature must have at least three vertices. Therefore, features like polylines, elliptical arcs, three-point arcs, Cardinal curves, Bezier curves, and B-spline curves support the auto-close lines function, while straight lines do not support automatic closure.
