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 a link below to view

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:
A small green circle indicates the start end point of the selected line segment.
A small red circle indicates the last end point of the selected line segment.
The same spline with end points indicating a selected spline segment.
