This application allows you to change the order of the vertices of the polyline.

The other properties polylines (coordinates, layer, color, thickness, etc.) are not changed after the change of this order.

Step 1. Select the polyline.
Step 2. Specify a point of the selected polyline, which should become the first vertex
Step 3: Specify a point of the selected polyline, which should become the second vertex
The order of vertices is changed.

If the polyline is closed, the first vertex can be any specified vertex of the selected polyline.
If the polyline is not closed, specify the vertices is not required.
