Protection Modes
In addition to the modes used to create a polyline, two other modes are used to protect the
points from further changes after they have been created.
Modify Only
Modify Only mode allows existing points on the polyline to be modified, but new points may not
be added to the shape.
The Modify Only toolbar button (Shift-M).
TIP: Even with Modify Only selected, it is still possible to delete points from a polyline.
Done
The Done mode prohibits the creation of any new points, as well as further modification of any
existing points on the polyline.
The Done toolbar button (Shift-N).
Closing Polylines
There are several ways to close a polyline, which will connect the last point to the first.
To close a polyline, do one of the following:
 Hover the pointer over the first point created, and then click on the point.
 Press Shift-O on the keyboard.
 Click the Close button on the polyline toolbar.
 Draw a polyline until you are ready to close the shape, and then right-click and choose
Polygon:Polyline > Closed.
The Close toolbar button (Shift-O).
All these options are toggles that can also be used to open a closed polygon.
