What is a Draw Object?
Draw objects are those objects you add to a draw file with the tools provided
in the Draw tab. Draw objects consist of line, area, or point objects. You can
copy, move, delete, and add draw objects to other draw files and add them to
another map file.
• Line objects are those objects consisting of line segments and points,
such as:
• Routable Roads
• Tracks
• Lines
• Arcs
• Splines
• Area objects are those objects consisting of one or more closed line
objects, such as:
• Polygons
• Rectangles
• Circles
• Point objects consist of one anchor point attached to either a waypoint,
symbol, MapNote, image, or text label. The anchor point is the pixel
position on the symbol that corresponds to the geographic coordinate
of the point selected on the map when the symbol is placed.
• Draw objects added to a draw file contain points that give the object
its shape or allow you to snap one object to another object. Points
display and act in different ways within the various draw objects. Click

Points in Routable Roads, Tracks, Lines, Splines, and Polygons
Draw objects such as routable roads, tracks, lines, splines, and polygons
consist of shape points and end points.
Shape points are the points you place on the map when creating the object.
They give the object its shape. When you select a draw object on the map,
shape points display along the active object as small magenta squares.
The line object below was drawn with the spline tool.
End points are the first and last points of individual line segments on a draw
object. When you select a shape point of a line segment within an active line,
spline, or polygon:
