Breaking (Opening) Closed Objects

Breaks a closed object (polygon, closed polyline, rectangle, closed curve, etc.), turning it into a polyline.

1. Use the Edit Tool on the closed object you want to break.
2. Right-click on the node at which you want the break, and select Break from the local menu.
3. The object is now an open polyline, with two end nodes at the node where you broke the object.
