Description
TrackLine returns a geometry object that implements IPolyline.
Remarks
Use the TrackLine method within the IMapControlEvents2::OnMouseDown event to rubberband a user defined line. The IMapControlEvents2::OnMouseMove event will be triggered during the track, but no IMapControlEvents2::OnMouseUp event will occur. The ESC key on the keyboard can be used during the track to cancel the TrackLine.
Calling ITopologicalOperator::Simplify on the digitized line will ensure that it is topologically correct.
