Move the Start and End Points for Areas
The start and end points for fill and satin areas are shown by circular markers. The start marker 
is on the inside of the object, and the end marker 
is on the outside of the object.
Click and drag the desired marker. Move the marker to the point that you wish to use as the new start or end point of the area. Drop at the desired point and the position of the marker will change.
The marker snaps to the nearest point on the edge of the object. If an area does not have a point in the desired position, use Insert Points
to add an extra point.
