Interaction of graphic polylines with the 2D polylines

When in the Polyline cursor mode the Edit > Save selection as polyline command saves the currently displayed polyline to the polylines module, giving the option to overwrite an existing polyline or create a new one.

Also, when in the polyline cursor mode the Edit > Select polyline menu command allows an existing polyline to be displayed as the current polyline.

On giving the Save selection as polyline or Select polyline command an association is formed between the current polyline and the saved polyline. This saved polyline is then offered as the default when calling these commands. The association is cleared when the current polyline is deleted.

Both Save selection as polyline and Select polyline are also available on the Graphic view right-click menu when in the Polyline cursor mode.
